Tomatoes (Solanum lycopersicum) plant were provided with bio-fertilizers issued from anaerobic digestion of olive mill wastewater without and with 1%, 5% of phosphate residues in mesophilic conditions for 25 days. 1% of raw substrates (OMW raw; OMW\u2009+\u20091%PR raw; olive mill wastewater\u2009+\u20095%phosphate residues raw; and phosphate residues) and digestates (olive mill wastewater digestate, olive mill wastewater\u2009+\u20091%phosphate residues digestate and olive mill wastewater\u2009+\u20095%phosphate residues digestate) was provided fortnightly to the plants. Reclaimed water from a wastewater treatment plant located in the study site was used for automatically controlled irrigation. It contained a low level of chemical fertilizers to compare tomato plant growth, leaf analysis, steam water potential, production yield and fruit quality results to plants fed with bio-fertilizers. Generally, parameters and results were progressively increased during the growing and harvesting stage, which refer to the essential elements that cover the plant\u2019s needs. Plants fed with bio-fertilizers showed the most extended plant height (olive mill wastewater\u2009+\u20095% phosphate residues raw), and the best accumulation of essential elements in leaves (olive mill wastewater\u2009+\u20091% phosphate residues digestate and olive mill wastewater\u2009+\u20095%phosphate residues digestate). The maximum average fruit weight per treatment (35.5 g) was obtained when applying the digestates mixture of olive mill wastewater raw and olive mill wastewater\u2009+\u20095% phosphate residues. The maximum yield production per plant was obtained when applying phosphates residues. Bio-fertilizers (digestates) showed good performances, high fruit quality and perfect tomato yield production compared to the control plants. Results obtained during this study are considered promising regarding environmental framework. However, this study was done in a laboratory scale and needs to be applied in a large scale to provide more data on the effectiveness of the digestates application. It is also recommended to apply these bio-fertilizers on different crops and various soils for a better evaluation.

This work investigated biological attributes in a gold mining area with different arsenic contents at different sites under two types of extant revegetation associated with cover layers of the soil: BS, Brachiaria sp. and Stizolobium sp., and LEGS, Acacia crassicarpa, A. holosericea, A. mangium, Sesbania virgata, Albizia lebbeck and Pseudosamanea guachapele. References were also evaluated, comprising the following three sites: B1, weathered sulfide substrate without revegetation; BM, barren material after gold extraction and PRNH (private reserve of natural heritage), an uncontaminated forest site near the mining area. The organic and microbial biomass carbon contents and substrate-induced respiration rates for these sites from highest to lowest were: PRNH > LEGS > BS > B1 and BM. These attributes were negatively correlated with soluble and total arsenic concentration in the soil. The sites that have undergone revegetation (LEGS and BS) had higher densities of bacteria, fungi, phosphate solubilizers and ammonium oxidizers than the sites without vegetation. Principal component analysis showed that the LEGS site grouped with PRNH, indicating that the use of leguminous species associated with an uncontaminated soil cover layer contributed to the improvement of the biological attributes. With the exception of acid phosphatase, all the biological attributes were indicators of soil recovery, particularly the following: microbial carbon, substrate-induced respiration, density of culturable bacteria, fungi and actinobacteria, phosphate solubilizers and metabolic quotient.", "keywords": ["Arsenic - Contamination", "Microbial biomass", "Quociente microbial", "01 natural sciences", "Mining", "Arsenic", "Photometry", "Respira\u00e7\u00e3o induzida por substrato", "Soil", "Substrate-induced respiration", "Soil Pollutants", "Biomass", "Microbial quotient", "Soil Microbiology", "0105 earth and related environmental sciences", "Ars\u00eanico - Contamina\u00e7\u00e3o", "Spectrophotometry", " Atomic", "Biomassa microbiana", "Phosphate solubilizers", "Solubilizantes de fosfato", "04 agricultural and veterinary sciences", "15.

Quantitative PCR was applied to evaluate the abundance of relevant microbial groups. Phosphorus availability and microbial biomass systematically increased in the rhizosphere compared to bulk soil. P-fertilization resulted in higher abundance of targeted bacterial phyla, whole bacterial and fungal communities, and depressed mycorrhizal colonization of durum wheat, but not faba bean. Microbial biomass carbon significantly increased in the rhizosphere only in P-fertilized treatments, pointing to P limitation of microbial communities. Intercropping yielded a significant effect on rhizosphere microbial properties only at High P. Microbial biomass P increased in the rhizosphere of intercropped faba bean only at No P level, and was thus the sole finding supporting the stress-gradient hypothesis.

Biochemistry is an essential yet often undervalued aspect of soil ecology, especially in soil C cycling. We assume based on tradition, intuition or hope that the complexity of biochemistry is confined to the microscopic world, and can be ignored when dealing with whole soil systems. This opinion paper draws attention to patterns caused by basic biochemical processes that permeate the world of ecosystem processes. From these patterns, we can estimate activities of the biochemical reactions of the central C metabolic network and gain insights into the ecophysiology of microbial biosynthesis and growth and maintenance energy requirements; important components of Carbon Use Efficiency (CUE).The biochemical pathways used to metabolize glucose vary from soil to soil, with mostly glycolysis in some soils, and pentose phosphate or Entner-Doudoroff pathways in others. However, notwithstanding this metabolic diversity, glucose use efficiency is high and thus substrate use for maintenance energy and overflow respiration is low in these three soils. These results contradict current dogma based on four decades of research in soil ecology. We identify three main shortcomings in our current understanding of substrate use efficiency: 1) in numeric and conceptual models, we lack appreciation of the strategies that microbes employ to quickly reduce energy needs in response to starvation; 2) production of exudates and microbial turnover affect whole-soil CUE more than variation in maintenance energy demand; and 3) whether tracer experiments can be used to measure the long-term substrate use efficiency of soil microbial communities depends critically on the ability of non-growing cells to take up tracer substrates, how biosynthesis responds to these substrates, as well as on how cellular activities scale to the community level.To move the field of soil ecology forward, future research must consider the details of microbial ecophysiology and develop new tools that enable direct measurement of microbial functioning in intact soils. We submit that 13C metabolic flux analysis is one of those new tools.

Increasing food demand coupled with climate change pose a great challenge to agricultural systems. In this review we summarize recent advances in our knowledge of how plants, together with their associated microbiota, shape rhizosphere processes. We address (molecular) mechanisms operating at the plant\uffe2\uff80\uff93microbe-soil interface and aim to link this knowledge with actual and potential avenues for intensifying agricultural systems, while at the same time reducing irrigation water, fertilizer inputs and pesticide use. Combining in-depth knowledge about above and belowground plant traits will not only significantly advance our mechanistic understanding of involved processes but also allow for more informed decisions regarding agricultural practices and plant breeding. Including belowground plant-soil-microbe interactions in our breeding efforts will help to select crops resilient to abiotic and biotic environmental stresses and ultimately enable us to produce sufficient food in a more sustainable agriculture in the upcoming decades.90% DW.

However, some agroforestry tree species adapted to P-fixing soils may be able to utilize less available P sources and concurrently increase P availability to adjacent crops. Adaptations for enhanced P acquisition from P-fixing soils include exudation of low molecular weight (LMW) organic anions (OA) and phosphatase enzymes. We identified major organic anions, and measured acid phosphatase activity and P fractions in the rhizosphere soil of maize (Zea mays\u00a0L.), as well as in the perennial species Grevillea robusta A. Cunn., Cassia spectabilis DC. (syn. Senna spectabilis (DC.) H.S. Irwin and R.C. Barneby), Tithonia diversifolia (Hemsl.) A. Gray, Eucalyptus grandis W. Hill ex Maiden and Cedrella serrata Royle. Maize and trees were grown simultaneously at field sites and in large pots. Rhizosphere soil of C.\u00a0spectabilis contained at least 29\u00a0\u03bcmol oxalate\u00a0g\u22121 soil, derived from a high exudation rate in the range of at least 5\u201310\u00a0\u03bcmol oxalate\u00a0m\u22121 root day\u22121. Incubation of Ferralsols with much lower concentrations of citrate increased labile P fractions, but there was no clear relation between OA concentration and an increase in labile P fractions in rhizosphere soils, where P mobilization and P uptake occur at the same time. Acid phosphatase activity in rhizosphere soil of all species was two to five times greater in rhizosphere soil compared with bulk soil, and correlated in rhizosphere soil of G.\u00a0robusta with a shift from organic P to inorganic P in soil P fractions. We conclude that organic anion exudation and acid phosphatase activity of tree roots may increase mobilization of P in the rhizosphere, the extent of which depends on the species, the organic anion and pH. However, it is unlikely that the extent of P mobilization will benefit adjacent crop plants unless crop roots exert insufficient P-mobilization effects themselves, and grow in the rhizosphere of tree roots.", "keywords": ["0106 biological sciences", "2.

Crops have different strategies to acquire poorly-available soil phosphorus (P) which are dependent on their architectural, morphological, and physiological root traits, but their capacity to enhance P acquisition varies with the type of fertilizer applied. The objective of this study was to examine how P-acquisition strategies of three main crops are affected by the application of sewage sludges, compared with a mineral P fertilizer. We carried out a 3-months greenhouse pot experiment and compared the response of P-acquisition traits among wheat, barley and canola in a soil amended with three sludges or a mineral P fertilizer. Results showed that the P-acquisition strategy differed among crops. Compared with canola, wheat and barley had a higher specific root length and a greater root carboxylate release and they acquired as much P from sludge as from mineral P. By contrast, canola shoot P content was greater with sludge than with mineral P. This was attributed to a higher root-released acid phosphatase activity which promoted the mineralization of sludge-derived P-organic. This study showed that contrasted P-acquisition strategies of crops allows increased use of renewable P resources by optimizing combinations of crop and the type of P fertilizer applied within the cropping system.Elevated nitrogen (N) deposition may aggravate phosphorus (P) deficiency in forests in the warm humid regions of China. To our knowledge, the interactive effects of long-term N deposition and P availability on soil microorganisms in tropical replanted forests remain unclear. We conducted an N and P manipulation experiment with four treatments: control, N addition (15\uffe2\uff80\uff89g N m\uffe2\uff88\uff922\uffc2\uffb7yr\uffe2\uff88\uff921), P addition (15\uffe2\uff80\uff89g P m\uffe2\uff88\uff922\uffc2\uffb7yr\uffe2\uff88\uff921) and N and P addition (15\uffe2\uff80\uff89+\uffe2\uff80\uff8915\uffe2\uff80\uff89g N and P m\uffe2\uff88\uff922\uffc2\uffb7yr\uffe2\uff88\uff921, respectively) in disturbed (planted pine forest with recent harvests of understory vegetation and litter) and rehabilitated (planted with pine, but mixed with broadleaf returning by natural succession) forests in southern China. Nitrogen addition did not significantly affect soil microbial biomass, but significantly decreased the abundance of gram-negative bacteria PLFAs in both forest types. Microbial biomass increased significantly after P addition in the disturbed forest but not in the rehabilitated forest. No interactions between N and P additions on soil microorganisms were observed in either forest type. Our results suggest that microbial growth in replanted forests of southern China may be limited by P rather than by N and this P limitation may be greater in disturbed forests.

Stable Ca isotopes are fractionated between bones, urine and blood of animals and between soils, roots and leaves of plants by >1000\uffe2\uff80\uff89ppm for the 44Ca/40Ca ratio. These isotopic variations have important implications to understand Ca transport and fluxes in living organisms; however, the mechanisms of isotopic fractionation are unclear. Here we present ab initio calculations for the isotopic fractionation between various aqueous species of Ca and show that this fractionation can be up to 3000\uffe2\uff80\uff89ppm. We show that the Ca isotopic fractionation between soil solutions and plant roots can be explained by the difference of isotopic fractionation between the different first shell hydration degree of Ca2+ and that the isotopic fractionation between roots and leaves is controlled by the precipitation of Ca-oxalates. The isotopic fractionation between blood and urine is due to the complexation of heavy Ca with citrate and oxalates in urine. Calculations are presented for additional Ca species that may be useful to interpret future Ca isotopic measurements.

Providing architectural surfaces with self-cleaning ability is one of the most promising routes of preventive conservation. To this aim, several methods have been proposed in the literature, based on the use of photocatalytic TiO2 nanoparticles, either directly applied onto the surfaces or incorporated in protective coatings. However, when nano-TiO2 is directly applied onto architectural surfaces, the particles are easily removed by rain. When TiO2 is incorporated in polymeric coatings, durability issues arise as well, because the photoactivity of TiO2 nanoparticles can promote degradation of the polymer. Here, we present an innovative alternative method, based on combination of TiO2 nanoparticles and hydroxyapatite (HAP). The incorporation of nano-TiO2 into an HAP coating protects the nanoparticles from leaching by rain, thanks to the chemical bonding between TiO2 and HAP, without diminishing their photoactivity. As a result, marble treated with HAP-TiO2 composites exhibits high self-cleaning ability and high durability, with results superior to those achieve by direct application of nano-TiO2 onto the surface, as frequently performed on site.", "keywords": ["Durability; Hydroxyapatite; Marble; Nanoparticles; Protective coatings; Rain", "02 engineering and technology", "ING-IND/22 Scienza e tecnologia dei materiali", "Soiling; Photocatalytic activity; Selfcleaning; Titanium dioxide; Hydroxyapatite; Calcium phosphate; Durability; Leaching", "IOP Conference Series: Materials Science and Engineering", "0210 nano-technology", "01 natural sciences", "0104 chemical sciences"]}, "links": [{"href": "https://cris.unibo.it/bitstream/11585/643036/1/Sassoni%20et%20al%20%282018%29%20Photocatalytic%20HAP-TiO2%20nano-composites.pdf"}, {"href": "https://doi.org/10.1088/1757-899X/364/1/012073"}, {"rel": "related", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/IOP%20Conference%20Series%3A%20Materials%20Science%20and%20Engineering", "name": "related record", "description": "related record", "type": "application/json"}, {"rel": "self", "type": "application/geo+json", "title": "10.1088/1757-899X/364/1/012073", "name": "item", "description": "10.1088/1757-899X/364/1/012073", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.1088/1757-899X/364/1/012073"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2018-06-01T00:00:00Z"}}, {"id": "10.1088/1757-899X/364/1/012092", "type": "Feature", "geometry": null, "properties": {"updated": "2026-07-27T16:19:02Z", "type": "Journal Article", "created": "2018-06-18", "title": "New insights on protective treatments for marble by FIB-SEM", "description": "In this study, we investigated by FIB-SEM the microstructure of protective coatings formed by two inorganic treatments (namely, ammonium oxalate and ammonium phosphate solutions), with the aim of identifying the factors limiting the protective efficacy of the coatings and outlining possible improvement strategies.

In this study, nodulated alfalfa plants were exposed to drought conditions. The study determined the physiological, metabolic, and proteomic processes involved in photosynthetic inhibition in relation to the decrease in nitrogenase (N(ase)) activity. The deleterious effect of drought on alfalfa performance was targeted towards photosynthesis and N(ase) activity. At the leaf level, photosynthetic inhibition was mainly caused by the inhibition of Rubisco. The proteomic profile and physiological measurements revealed that the reduced carboxylation capacity of droughted plants was related to limitations in Rubisco protein content, activation state, and RuBP regeneration. Drought also decreased amino acid content such as asparagine, and glutamic acid, and Rubisco protein content indicating that N availability limitations were caused by N(ase) activity inhibition. In this context, drought induced the decrease in Rubisco binding protein content at the leaf level and proteases were up-regulated so as to degrade Rubisco protein. This degradation enabled the reallocation of the Rubisco-derived N to the synthesis of amino acids with osmoregulant capacity. Rubisco degradation under drought conditions was induced so as to remobilize Rubisco-derived N to compensate for the decrease in N associated with N(ase) inhibition. Metabolic analyses showed that droughted plants increased amino acid (proline, a major compound involved in osmotic regulation) and soluble sugar (D-pinitol) levels to contribute towards the decrease in osmotic potential (\u03a8(s)). At the nodule level, drought had an inhibitory effect on N(ase) activity. This decrease in N(ase) activity was not induced by substrate shortage, as reflected by an increase in total soluble sugars (TSS) in the nodules. Proline accumulation in the nodule could also be associated with an osmoregulatory response to drought and might function as a protective agent against ROS. In droughted nodules, the decrease in N(2) fixation was caused by an increase in oxygen resistance that was induced in the nodule. This was a mechanism to avoid oxidative damage associated with reduced respiration activity and the consequent increase in oxygen content. This study highlighted that even though drought had a direct effect on leaves, the deleterious effects of drought on nodules also conditioned leaf responsiveness.", "keywords": ["Proteomics", "0301 basic medicine", "570", "Rubisco", "Proteome", "[SDV]Life Sciences [q-bio]", "proteome", "N-2 FIXATION RESPONSE", "drought", "N2 fixation", "03 medical and health sciences", "XANTHOPHYLL CYCLE", "N-2 fixation", "2-CYSTEINE PEROXIREDOXIN", "Nitrogenase", "oxidative stress", "AMINO-ACIDS", "Photosynthesis", "climate", "agriculture", "Plant Proteins", "580", "N remobilization", "2.

Copper (Cu) is a cofactor of around 300 Arabidopsis proteins, including photosynthetic and mitochondrial electron transfer chain enzymes critical for adenosine triphosphate (ATP) production and carbon fixation. Plant acclimation to Cu deficiency requires the transcription factor SQUAMOSA PROMOTER-BINDING PROTEIN-LIKE7 (SPL7). We report that in the wild type (WT) and in the spl7-1 mutant, respiratory electron flux via Cu-dependent cytochrome c oxidase is unaffected under both normal and low-Cu cultivation conditions. Supplementing Cu-deficient medium with exogenous sugar stimulated growth of the WT, but not of spl7 mutants. Instead, these mutants accumulated carbohydrates, including the signaling sugar trehalose 6-phosphate, as well as ATP and NADH, even under normal Cu supply and without sugar supplementation. Delayed spl7-1 development was in agreement with its attenuated sugar responsiveness. Functional TARGET OF RAPAMYCIN and SNF1-RELATED KINASE1 signaling in spl7-1 argued against fundamental defects in these energy-signaling hubs. Sequencing of chromatin immunoprecipitates combined with transcriptome profiling identified direct targets of SPL7-mediated positive regulation, including Fe SUPEROXIDE DISMUTASE1 (FSD1), COPPER-DEFICIENCY-INDUCED TRANSCRIPTION FACTOR1 (CITF1), and the uncharacterized bHLH23 (CITF2), as well as an enriched upstream GTACTRC motif. In summary, transducing energy availability into growth and reproductive development requires the function of SPL7. Our results could help increase crop yields, especially on Cu-deficient soils.We investigated whether the degree of light inhibition of leaf respiration (R) differs among large Eucalyptus saligna grown in whole\uffe2\uff80\uff90tree chambers and exposed to present and future atmospheric [CO2] and summer drought. Associated with month\uffe2\uff80\uff90to\uffe2\uff80\uff90month changes in temperature were concomitant changes in R in the light (Rlight) and darkness (Rdark), with both processes being more temperature dependent in well\uffe2\uff80\uff90watered trees than under drought. Overall rates of Rlight and Rdark were not significantly affected by [CO2]. By contrast, overall rates of Rdark (averaged across both [CO2]) were ca. 25% lower under drought than in well\uffe2\uff80\uff90watered trees. During summer, the degree of light inhibition of leaf R was greater in droughted (ca. 80% inhibition) than well\uffe2\uff80\uff90watered trees (ca. 50% inhibition). Notwithstanding these treatment differences, an overall positive relationship was observed between Rlight and Rdark when data from all months/treatments were combined (R2\uffe2\uff80\uff83=\uffe2\uff80\uff830.8). Variations in Rlight were also positively correlated with rates of Rubisco activity and nitrogen concentration. Light inhibition resulted in a marked decrease in the proportion of light\uffe2\uff80\uff90saturated photosynthesis respired (i.e. reduced R/Asat). Collectively, these results highlight the need to account for light inhibition when assessing impacts of global change drivers on the carbon economy of tree canopies.

The drought\uffe2\uff80\uff90 and thermo\uffe2\uff80\uff90tolerant Quercus pubescens, a tree species growing on both acidic and calcareous soils in the sub\uffe2\uff80\uff90Mediterranean region, was exposed to soil drought (\uffe2\uff88\uff9260% to \uffe2\uff88\uff9280% soil water content) and air warming (+1.2\uffe2\uff80\uff83\uffc2\uffb0C daytime temperature), singly and in combination. The experiment was conducted on two natural forest soils with similar texture but different pH (acidic and calcareous soils). The physiological (photosynthesis) and biochemical (antioxidant system) responses of Q.\uffc2\uffa0pubescens were investigated. On acidic soil, Q.\uffc2\uffa0pubescens had a higher reactive oxygen species (ROS) content than on calcareous soil, confirming that this species is better adapted to the latter soil type. A down\uffe2\uff80\uff90regulation of ascorbate\uffe2\uff80\uff90glutathione cycle enzymes suggests that ROS were used as signalling molecules. Air warming stimulated stomatal opening, while soil drought induced stomatal closure in the late afternoon and reduced Rubisco carboxylation efficiency. Photosynthetic performance in the combined treatment was higher than under single drought stress and similar to control and air warming. Q.\uffc2\uffa0pubescens biochemical responses depended on soil pH. On acidic soil, Q.\uffc2\uffa0pubescens trees exposed to air warming used ROS as signalling molecules. On calcareous soil, these trees were able to balance both soil drought and air warming stress, avoiding ROS toxic effects by increasing antioxidant enzyme activitiy and maintaining a high enzymatic antioxidant defence. When combined, drought and air warming induced either more severe (higher oxidative pressure and impairment of the light\uffe2\uff80\uff90harvesting complex) or different responses (decline of the thermal energy dissipation capacity) relative to the single stressors. Overall, however, Q.\uffc2\uffa0pubescens preserved the functionality of the photosynthetic apparatus and controlled the antioxidant system response, thus confirming its drought and thermo\uffe2\uff80\uff90tolerance and therefore its potential to adapt to the ongoing climate change.

Research is needed on novel consolidants to restore weathered marble, because the available products exhibit limitations. To test new consolidants, samples with features similar to naturally weathered marble (i.e., near\uffe2\uff80\uff90surface damage) are recommended. We developed a novel method that produces decayed samples with a gradient in properties that can be tuned to any desired level, in terms of depth from the surface and decrease in dynamic elastic modulus. The idea is to produce near\uffe2\uff80\uff90surface damage by putting a marble sample in contact with a plate at a certain temperature for a certain time, calculated by a mathematical model. The model was used to predict the heating conditions to produce a certain decrease in dynamic elastic modulus in the first 1\uffc2\uffa0cm from the surface, comparable to naturally weathered marble. Good confirmation of the model predictions was found experimentally. The suitability of using thermally \uffe2\uff80\uff9cweathered\uffe2\uff80\uff9d samples for testing consolidants was demonstrated in the case of a hydroxyapatite\uffe2\uff80\uff90based treatment. The mathematical model can be tailored to other lithotypes or ceramics, using the relevant property data.

The imbalance between nitrogen (N) and phosphorus (P) deposition may shift temperate ecosystems from N\uffe2\uff80\uff90 to P\uffe2\uff80\uff90limitation. However, it is unclear how the imbalanced N\uffc2\uffa0:\uffc2\uffa0P input affects the strategies of plants to acquire P and, therefore, the growth of plants and the competition among species.

We conducted a 4\uffe2\uff80\uff90yr N\uffe2\uff80\uff90addition experiment in young and mature larch (Larix principis\uffe2\uff80\uff90rupprechtii) stands. Plant growth and P acquisition strategies were assessed for larch and understorey vegetation.

N addition stimulated the aboveground productivity of understorey vegetation in the young stand and larch in the mature stand, with other species unaffected. The competitive advantages of understorey vegetation in the young stand and larch in the mature stand were associated with their high stoichiometric homoeostasis. To maintain the N\uffc2\uffa0:\uffc2\uffa0P homoeostasis of these species, an increase in phosphatase activity but not P resorption efficiency increased the supply of P. Additionally, N addition accelerated P mineralization by decreasing the fungal\uffe2\uff80\uff90to\uffe2\uff80\uff90bacterial ratios and improved uptake of soil P by increasing the arbuscular mycorrhizas\uffe2\uff80\uff90to\uffe2\uff80\uff90ectomycorrhizas ratios.

Our results suggest that plants with high stoichiometric homoeostasis could better cope with N deposition\uffe2\uff80\uff90induced P\uffe2\uff80\uff90deficiency.

Summary

The evolutionary and ecological success of the arbuscular mycorrhizal (AM) symbiosis relies on an efficient and multifactorial communication system for partner recognition, and on a fine\uffe2\uff80\uff90tuned and reciprocal metabolic regulation of each symbiont to reach an optimal functional integration. Besides strigolactones, N\uffe2\uff80\uff90acetylglucosamine\uffe2\uff80\uff90derivatives released by the plant were recently suggested to trigger fungal reprogramming at the pre\uffe2\uff80\uff90contact stage. Remarkably, N\uffe2\uff80\uff90acetylglucosamine\uffe2\uff80\uff90based diffusible molecules also are symbiotic signals produced by AM fungi (AMF) and clues on the mechanisms of their perception by the plant are emerging. AMF genomes and transcriptomes contain a battery of putative effector genes that may have conserved and AMF\uffe2\uff80\uff90 or host plant\uffe2\uff80\uff90specific functions. Nutrient exchange is the key feature of AM symbiosis. A mechanism of phosphate transport inside fungal hyphae has been suggested, and first insights into the regulatory mechanisms of root colonization in accordance with nutrient transfer and status were obtained. The recent discovery of the dependency of AMF on fatty acid transfer from the host has offered a convincing explanation for their obligate biotrophism. Novel studies highlighted the importance of plant and fungal genotypes for the outcome of the symbiosis. These findings open new perspectives for fundamental research and application of AMF in agriculture.

Root citrate exudation is thought to be important for phosphate solubilization. Previous research has concluded that cluster\uffe2\uff80\uff90like roots benefit most from this exudation in terms of increased phosphate uptake, suggesting that root structure plays an important role in citrate\uffe2\uff80\uff90enhanced uptake (additional phosphate uptake due to citrate exudation).

Time\uffe2\uff80\uff90resolved computed tomography images of wheat root systems were used as the geometry for 3D citrate\uffe2\uff80\uff90phosphate solubilization models. Citrate\uffe2\uff80\uff90enhanced uptake was correlated with morphological measures of the root systems to determine which had the most benefit.

A large variation of citrate\uffe2\uff80\uff90enhanced uptake over 11 root structures was observed. Root surface area dominated absolute phosphate uptake, but did not explain citrate\uffe2\uff80\uff90enhanced uptake. Number of exuding root tips correlated well with citrate\uffe2\uff80\uff90enhanced uptake. Root tips in close proximity could collectively exude high amounts of citrate, resulting in a delayed spike in citrate\uffe2\uff80\uff90enhanced uptake.

Root system architecture plays an important role in citrate\uffe2\uff80\uff90enhanced uptake. Singular morphological measurements of the root systems cannot entirely explain variations in citrate\uffe2\uff80\uff90enhanced uptake. Root systems with many tips would benefit greatly from citrate exudation. Quantifying citrate\uffe2\uff80\uff90enhanced uptake experimentally is difficult as variations in root surface area would overwhelm citrate benefits.

Cluster root (CR) is one of the most spectacular plant developmental adaptations to hostile environment. It can be found in a few species from a dozen botanical families, including white lupin (Lupinus albus) in the Fabaceae family. These amazing structures are produced in phosphate\uffe2\uff80\uff90deprived conditions and are made of hundreds of short roots also known as rootlets. White lupin is the only crop bearing CRs and is considered as the model species for CR studies. However, little information is available on CRs atypical development, including the molecular events that trigger their formation. To provide insights on CR formation, we performed an anatomical and cellular description of rootlet development in white lupin. Starting with a classic histological approach, we described rootlet primordium development and defined eight developmental stages from rootlet initiation to their emergence. Due to the major role of hormones in the developmental program of root system, we next focussed on auxin\uffe2\uff80\uff90related mechanisms. We observed the establishment of an auxin maximum through rootlet development in transgenic roots expressing the DR5:GUS auxin reporter. Expression analysis of the main auxin\uffe2\uff80\uff90related genes [TIR, Auxin Response Factor (ARF) and AUX/IAA] during a detailed time course revealed specific expression associated with the formation of the rootlet primordium. We showed that L. albus TRANSPORT INHIBITOR RESPONSE 1b is expressed during rootlet primordium formation and that L. albus AUXIN RESPONSE FACTOR 5 is expressed in the vasculature but absent in the primordium itself. Altogether, our results describe the very early cellular events leading to CR formation and reveal some of the auxin\uffe2\uff80\uff90related mechanisms.

N & P fertilization is widely accepted to recover degraded pastures in other regions all over the world. However, it is not clear how alpine steppe communities respond to N & P fertilization, and what is the optimal application rate, in the perspective of forage production. To attempt to explore these questions, in July 2013, two fencing sites were designed in Baingoin County with 12 treatments of different levels of nitrogen (N0: 0; N1: 7.5 g m(-2) yr(-1); N2: 15 g m(-2) yr(-1)) & phosphate (P0: 0; P1: 7.5 gP2O5 m(-2) yr(-1); P2: 15 gP2O5 m(-2) yr(-1); P3: 30 gP2O5 m(-2) yr(-1)). The results indicated N&P addition was capable to ameliorate the quality of the two sites in the Tibetan Plateau steppe. Increasing N application level resulted in significant increment in Gramineae and total biomass in the two sites. P addition significantly improved the quantity of Compositae, total biomass and the biomasss of other species in site II, while it only significantly improved the total biomass in site I. Gramineae was much more sensitive to N-induced changes than P-induced changes, and this indicated N addition was better to ameliorate the quality of plateau steppe than P-induced changes. No strong evidence was found for critical threshold within 15 g N m(-2) yr(-1), and there was decreasing tendency when P addition rate was above 15 g m(-2) yr(-1). N&P has the potential to accelerate soil acidification, which improved the content of available K, likely as a result of nonsignificant correlation between biomass and soil moisture.

Wie P in Sedimenten gebunden ist, wirkt sich auf dessen Bioverf\u00fcgbarkeit aus. Unter reduzierenden, sulfid-freien Bedingungen kann das eisenhaltige Phosphatmineral Vivianit eine wesentliche Rolle bei der P-Bindung in K\u00fcstensedimenten spielen und somit die Wasserqualit\u00e4t positiv beeinflussen. Trotz der Bedeutung von Vivianit f\u00fcr die Regulierung der P-Verf\u00fcgbarkeit in K\u00fcstensedimenten sind die in-situ Bildung, Zusammensetzung und Stabilit\u00e4t von Vivianit nur unzureichend untersucht. In dieser Doktorarbeit wurden Feldexperimente mit einer Laborstudie kombiniert, um die Bildungs- und Umwandlungsprozesse von Vivianit in gezeitenbeeinflussten Sedimenten und den Einfluss der isomorphen Substitution auf diese Prozesse aufzudecken. Diese Erkenntnisse bieten wertvolle Einblicke in die Prozesse des P-Kreislaufs in K\u00fcstensedimenten und sind bedeutend f\u00fcr die Entwicklung industrieller Anwendungen, die darauf abzielen, den anthropogenen P-Kreislauf zu schlie\u00dfen. Im ersten Teil der Arbeit wurde eine Methode entwickelt, bei der isotopisch 57Fe-markiertes Ferrihydrit mit dem Sediment vermischt wurde, um die Vivianitbildung in-situ in gezeitenbeeinflussten Sedimenten zu verfolgen. Mit dieser Methode konnte gezeigt werden, dass sich Vivianit innerhalb von sieben Wochen in gezeitenbeeinflussten Sedimenten mit g\u00fcnstigen geochemischen Bedingungen bilden kann. Die Adsorption von Phosphat an Ferrihydrit war ein wesentlicher Vorl\u00e4ufer f\u00fcr die Bildung von Vivianit. Die reduktive Aufl\u00f6sung des Ferrihydrits bildete wahrscheinlich lokale Bedingen, welche n\u00f6tig waren, um die Vivianitbildung auszul\u00f6sen. W\u00e4hrend das gebildete Vivianit nur ein kleiner Teil des Eisen (Fe)-Pools war (bis zu 15%), machte es bis zu 72% des P-Pools aus basierend auf st\u00f6chiometrischen Berechnungen. Diese Ergebnisse zeigen, dass Vivianit eine entscheidende Rolle bei der Regulierung der P-Retention in K\u00fcstensedimenten spielen kann. In der Umwelt enth\u00e4lt Vivianit h\u00e4ufig andere zweiwertige Kationen, wie Mangan (Mn) und Magnesium (Mg), die in der Kristallstruktur Fe ersetzen. Im zweiten Experiment wurde untersucht, ob Mn oder Mg bei unterschiedlichen Salzgehalten bevorzugt eingebaut wird und wie die isomorphe Substitution die Kristallstruktur und Morphologie ver\u00e4ndert. Die Synthese von neunzehn Vivianiten mit unterschiedlichen Mn- und/oder Mg-Konzentrationen bei verschiedenen Salzgehalten ergab, dass bei niedriger Ionenst\u00e4rke sowohl Mn als auch Mg Fe in der Kristallstruktur gleichwertig ersetzen k\u00f6nnen, wobei Mn bei h\u00f6herer Ionenst\u00e4rke bevorzugt wurde. Vivianit weist zwei unterschiedliche Fe-Atompositionen auf. Die Substitution von Fe durch Mn und/oder Mg fand vorzugsweise an der Atomposition statt, welche Elektronentransfer ausf\u00fchren kann, wodurch Vivianit gegen Oxidation stabilisiert wird. Somit kann sich die isomorphe Substitution wahrscheinlich direkt auf das Oxidationsverhalten von Vivianit auswirken. Au\u00dferdem f\u00fchrte die isomorphe Substitution zu kleineren, raueren Kristallen mit geringerer Kristallinit\u00e4t. Diese beobachteten Ver\u00e4nderungen k\u00f6nnten sich auf die Reaktivit\u00e4t von Vivianit in der Umwelt auswirken, weshalb die isomorphe Substitution bei der Untersuchung der Reaktivit\u00e4t von Vivianit ber\u00fccksichtigt werden sollte. Umweltver\u00e4nderungen, einschlie\u00dflich des Anstiegs des Meeresspiegels, k\u00f6nnten die Bildung von Sulfid in derzeit nicht sulfidischen Sedimenten, die Vivianit enthalten, verst\u00e4rken und zu thermodynamisch instabilen Bedingungen f\u00fcr Vivianit f\u00fchren. Das letzte Experiment untersuchte die in-situ Stabilit\u00e4t von unsubstituiertem und Mn-Mg-substituiertem Vivianit, gemischt mit Meeressand und mit oder ohne die Zugabe von Kalziumkarbonat. Die Mischungen wurden 56 Tage lang in zwei Gezeitenzonen inkubiert, von denen ein Standort eine niedrige und der andere eine hohe Sulfidkonzentration aufwies. Die Inkubation von unsubstituiertem und Mn-Mg-substituiertem Vivianit bei unterschiedlichen Sulfidkonzentrationen ergab eine teilweise Aufl\u00f6sung von Vivianit, die durch die isomorphe Substitution deutlich verst\u00e4rkt wurde. Der gr\u00f6\u00dfte Teil der verbleibenden Mineralphase wurde weiterhin als Vivianit charakterisiert, was darauf hindeutet, dass ein Teil des Vivianits \u00fcber die Versuchsdauer erhalten blieb. Bei niedrigen Sulfidkonzentrationen war Gr\u00fcner Rost das Hauptumwandlungsprodukt, das wahrscheinlich einen Teil des freigesetzten Phosphats adsorbierte. Bei hohem Sulfidgehalt dominierte die Bildung von Fe-Sulfidmineralen, welche aufgrund der geringen Sorptionskapazit\u00e4t f\u00fcr Phosphat zu einem erh\u00f6hten P-Verlust f\u00fchrte. Ein erh\u00f6htes Sorptionspotenzial f\u00fcr Phosphat durch die Zugabe von Kalziumkarbonat k\u00f6nnte den Phosphatverlust geringf\u00fcgig verringern. Diese Ergebnisse zeigen, dass vivianithaltige Sedimente als Quelle f\u00fcr bioverf\u00fcgbares Phosphat dienen k\u00f6nnen, wenn sich die geochemischen Bedingungen \u00e4ndern. Diese Arbeit liefert neue experimentelle Ans\u00e4tze zur Untersuchung und Quantifizierung von Umwandlungs- und Bildungsprozessen von Vivianit. Die Ergebnisse zeigen eine schnelle in-situ Bildungskinetik, w\u00e4hrend die Aufl\u00f6sung von Vivianit unter den untersuchten Bedingungen langsam verl\u00e4uft. Die schnelle in-situ Bildungskinetik deutet darauf hin, dass die Vivianitbildung die P-Retention in Umgebungen mit sowohl schwankenden als auch stabilen geochemischen Bedingungen regulieren kann. Die Ver\u00e4nderungen der Kristallstruktur und -morphologie durch isomorphe Substitution erh\u00f6hten das Ausma\u00df der Aufl\u00f6sung und Umwandlung des Vivianits. Aufgrund der langsamen in-situ Aufl\u00f6sung k\u00f6nnte Vivianit bei kurzfristigen Umweltst\u00f6rungen eine stabile P-Retentionsphase darstellen. Langfristig destabilisierende Bedingungen k\u00f6nnten jedoch zu einer vollst\u00e4ndigen Aufl\u00f6sung f\u00fchren und die P-Retentionskapazit\u00e4t des Sediments schw\u00e4chen. Die Ergebnisse unterstreichen die Bedeutung von Vivianit als P-Retentionsphase in salzarmen K\u00fcstensedimenten, k\u00f6nnten aber auch f\u00fcr das Verst\u00e4ndnis von Bildungs- und Umwandlungsprozessen von Vivianit in anderen Umweltsystemen, wie limnischen Sedimenten und B\u00f6den in Feuchtgebieten, von Bedeutung sein.

Biochemistry is an essential yet often undervalued aspect of soil ecology, especially in soil C cycling. We assume based on tradition, intuition or hope that the complexity of biochemistry is confined to the microscopic world, and can be ignored when dealing with whole soil systems. This opinion paper draws attention to patterns caused by basic biochemical processes that permeate the world of ecosystem processes. From these patterns, we can estimate activities of the biochemical reactions of the central C metabolic network and gain insights into the ecophysiology of microbial biosynthesis and growth and maintenance energy requirements; important components of Carbon Use Efficiency (CUE).The biochemical pathways used to metabolize glucose vary from soil to soil, with mostly glycolysis in some soils, and pentose phosphate or Entner-Doudoroff pathways in others. However, notwithstanding this metabolic diversity, glucose use efficiency is high and thus substrate use for maintenance energy and overflow respiration is low in these three soils. These results contradict current dogma based on four decades of research in soil ecology. We identify three main shortcomings in our current understanding of substrate use efficiency: 1) in numeric and conceptual models, we lack appreciation of the strategies that microbes employ to quickly reduce energy needs in response to starvation; 2) production of exudates and microbial turnover affect whole-soil CUE more than variation in maintenance energy demand; and 3) whether tracer experiments can be used to measure the long-term substrate use efficiency of soil microbial communities depends critically on the ability of non-growing cells to take up tracer substrates, how biosynthesis responds to these substrates, as well as on how cellular activities scale to the community level.To move the field of soil ecology forward, future research must consider the details of microbial ecophysiology and develop new tools that enable direct measurement of microbial functioning in intact soils. We submit that 13C metabolic flux analysis is one of those new tools.To prevent soiling of marble exposed outdoors, the use of TiO2 nano-particles has been proposed in the literature by two main routes, both raising durability issues: (i) direct application to marble surface, with the risk of particle leaching by rainfall; (ii) particle incorporation into inorganic or organic coatings, with the risk of organic coating degradation catalyzed by TiO2 photoactivity. Here, we investigated the combination of nano-TiO2 and hydroxyapatite (HAP), previously developed for marble protection against dissolution in rain and mechanical consolidation. HAP-TiO2 combination was investigated by two routes: (i) sequential application of HAP followed by nano-TiO2 (\uffe2\uff80\uff9cH+T\uffe2\uff80\uff9d); (ii) simultaneous application by introducing nano-TiO2 into the phosphate solution used to form HAP (\uffe2\uff80\uff9cHT\uffe2\uff80\uff9d). The self-cleaning ability was evaluated before and after prolonged exposure to simulated rain. \uffe2\uff80\uff9cH+T\uffe2\uff80\uff9d and \uffe2\uff80\uff9cHT\uffe2\uff80\uff9d coatings exhibited much better resistance to nano-TiO2 leaching by rain, compared to TiO2 alone. In \uffe2\uff80\uff9cH+T\uffe2\uff80\uff9d samples, TiO2 nano-particles adhere better to HAP (having flower-like morphology and high specific surface area) than to marble. In \uffe2\uff80\uff9cHT\uffe2\uff80\uff9d samples, thanks to chemical bonds between nano-TiO2 and HAP, the particles are firmly incorporated in the HAP coating, which protects them from leaching by rain, without diminishing their photoactivity and without being degraded by them.

The present paper reviews the methods and the performance of in situ formation of calcium phosphates (CaP) for the conservation of materials belonging to cultural heritage. The core idea is to form CaP (ideally hydroxyapatite, HAP, the most stable CaP at pH > 4) by reaction between the substrate and an aqueous solution of a phosphate salt. Initially proposed for the conservation of marble and limestone, the treatment has been explored for a variety of different substrates, including sandstones, sulphated stones, gypsum stuccoes, concrete, wall paintings, archaeological bones and paper. First, the studies aimed at identifying the best treatment conditions (e.g., nature and concentration of the phosphate precursor, solution pH, treatment duration, ionic and organic additions to the phosphate solution, mineralogical composition of the new CaP phases) are summarized. Then, the treatment performance on marble and limestone is reviewed, in terms of protective and consolidating effectiveness, compatibility (aesthetic, microstructural and physical) and durability. Some pilot applications in real case studies are also reported. Recent research aimed at extending the phosphate treatment to other substrates is then illustrated. Finally, the strengths of the phosphate treatment are summarized, in comparison with alternative products, and some aspects needing future research are outlined.

Crops have different strategies to acquire poorly-available soil phosphorus (P) which are dependent on their architectural, morphological, and physiological root traits, but their capacity to enhance P acquisition varies with the type of fertilizer applied. The objective of this study was to examine how P-acquisition strategies of three main crops are affected by the application of sewage sludges, compared with a mineral P fertilizer. We carried out a 3-months greenhouse pot experiment and compared the response of P-acquisition traits among wheat, barley and canola in a soil amended with three sludges or a mineral P fertilizer. Results showed that the P-acquisition strategy differed among crops. Compared with canola, wheat and barley had a higher specific root length and a greater root carboxylate release and they acquired as much P from sludge as from mineral P. By contrast, canola shoot P content was greater with sludge than with mineral P. This was attributed to a higher root-released acid phosphatase activity which promoted the mineralization of sludge-derived P-organic. This study showed that contrasted P-acquisition strategies of crops allows increased use of renewable P resources by optimizing combinations of crop and the type of P fertilizer applied within the cropping system.
