Boreal forests are ecosystems with low nitrogen (N) availability that store globally significant amounts of carbon (C), mainly in plant biomass and soil organic matter (SOM). Although crucial for future climate change predictions, the mechanisms controlling boreal C and N pools are not well understood. Here, using a three-year field experiment, we compare SOM decomposition and stabilization in the presence of roots, with exclusion of roots but presence of fungal hyphae and with exclusion of both roots and fungal hyphae. Roots accelerate SOM decomposition compared to the root exclusion treatments, but also promote a different soil N economy with higher concentrations of organic soil N compared to inorganic soil N accompanied with the build-up of stable SOM-N. In contrast, root exclusion leads to an inorganic soil N economy (i.e., high level of inorganic N) with reduced stable SOM-N build-up. Based on our findings, we provide a framework on how plant roots affect SOM decomposition and stabilization.

To gain insight into the impact of various soil conditions on nutritional and phytochemical properties, aerial parts of caper bush (C. spinosa) were collected from gypsum and non-gypsum soils in southern Iran. Colorimetric analyses of antioxidant compounds (total phenolics and flavonoids) and antioxidant capacity tests (DPPH, FRAP, ABTS) were carried out, and intact aliphatic and indolic glucosinolates (predominant aliphatic glucocapparin) were analyzed by HPLC-DAD method. Based on the findings, plant parts and sites significantly impacted most parameters. The highest TPC values were observed in the petals in gypsum soil and the lowest in the non-gypsum soil seeds by 2317.78 and 635.06\u00a0mg/kg FW, respectively. Likewise, the highest TFC was recorded in the non-gypsum soil leaves and the lowest in the non-gypsum soil seeds by 401.06 and 55.61 Qu mg/kg FW, respectively. The highest and lowest FRAP values were observed in the leaves in gypsum (0.94) and the pistils in gypsum soil (0.80), respectively. Regarding ABTS values, the flags in the non-gypsum and gypsum sites showed the highest and lowest values of 89.51 and 78.40%, respectively. High DPPH values were recorded for most parts. The highest amount of glucocapparin was found in the pistils in gypsum, and the lowest was in the petals in gypsum soil by 35.81 and 21.65 \u00b5mol/g DW, respectively. The gypsum sites showed higher values for most of the studied parameters. The PCA results showed that pistils were associated with glucocapparin, petals with DPPH, and the leaves and sepals with TPC, FRAP, ABTS, and TFC. The majority of studied factors correlated well with TPC.

Yet the impact of grazing disturbance on crust properties and soil CO 2 efflux remain poorly studied, particularly in African ecosystems. The effects of burial under wind-blown sand, disaggregation and removal of BSCs on seasonal variations in soil CO 2 efflux, soil organic carbon, chlorophyll a and scytonemin were investigated at two sites in the Kalahari of southern Botswana. Field experiments were employed to isolate CO 2 efflux originating from BSCs in order to estimate the C exchange within the crust. Organic carbon was not evenly distributed through the soil profile but concentrated in the BSC. Soil CO 2 efflux was higher in Kalahari Sand than in calcrete soils, but rates varied significantly with seasonal changes in moisture and temperature. BSCs at both sites were a small net sink of C to the soil. Soil CO 2 efflux was significantly higher in sand soils where the BSC was removed, and on calcrete where the BSC was buried under sand. The BSC removal and burial under sand also significantly reduced chlorophyll a , organic carbon and scytonemin . Disaggregation of the soil crust, however, led to increases in chlorophyll a and organic carbon. The data confirm the importance of BSCs for C cycling in drylands and indicate intensive grazing, which destroys BSCs through trampling and burial, will adversely affect C sequestration and storage. Managed grazing, where soil surfaces are only lightly disturbed, would help maintain a positive carbon balance in African drylands.

Warming can alter above\uffe2\uff80\uff90 and belowground linkages that regulate soil organic carbon dynamics and C\uffe2\uff80\uff90balance in peatlands. Here we examine the multiyear impact of in situ experimental warming on the microbial food web, vegetation, and their feedbacks with soil chemistry. We provide evidence of both positive and negative impacts of warming on specific microbial functional groups, leading to destabilization of the microbial food web. We observed a strong reduction (70%) in the biomass of top\uffe2\uff80\uff90predators (testate amoebae) in warmed plots. Such a loss caused a shortening of microbial food chains, which in turn stimulated microbial activity, leading to slight increases in levels of nutrients and labile C in water. We further show that warming altered the regulatory role of Sphagnum\uffe2\uff80\uff90polyphenols on microbial community structure with a potential inhibition of top predators. In addition, warming caused a decrease in Sphagnum cover and an increase in vascular plant cover. Using structural equation modelling, we show that changes in the microbial food web affected the relationships between plants, soil water chemistry, and microbial communities. These results suggest that warming will destabilize C and nutrient recycling of peatlands via changes in above\uffe2\uff80\uff90 and belowground linkages, and therefore, the microbial food web associated with mosses will feedback positively to global warming by destabilizing the carbon cycle. This study confirms that microbial food webs thus constitute a key element in the functioning of peatland ecosystems. Their study can help understand how mosses, as ecosystem engineers, tightly regulate biogeochemical cycling and climate feedback in peatlands

In this perspective, the present research was aimed at the complete valorisation of Garganega grape pomace by recovering bioactive phenol extracts and by testing the solid fibre extract residues in composite formulation for packaging applications. The pomace was derived from white wine production, therefore, respect to red pomace, it was promptly removed from must after pressing, and its exploitation can be particularly interesting and valuable as still rich in active compounds. Phenol extracts were obtained both via solvent-based and pressurised liquid extractions and their phytochemical compositions were compared in terms of total amount of phenols, flavonoids, flavanols, anthocyanins, hydroxycinnamic acids, and reducing sugars. Antioxidant activity and detailed phenol profiles were also achieved. The highest phenol yield was obtained via solvent-based extraction with 75% acetone (v/v), solid/liquid ratio 1:5, 2h incubation at 50\u00b0C (77.9 gGAeq/kgDW). The fibrous solid residue of the extraction was characterized via thermogravimetric analysis and used for composite preparation by melt mixing with the renewable and biodegradable PHBV polymer through a green approach (solvent-less process). The composites resulted thermally stable at high temperatures, showing initial degradation processes only at temperatures higher than 250\u00b0C. Differential scanning calorimetry analyses were carried out to study melting and crystallization phenomena, while mechanical properties were investigated by tensile tests. The materials finally showed properties similar to those of the matrix.

In addition to being an interesting source of polyphenols, they can be used as fillers in a poly(3-hydroxybutyrate-3-hydroxyvalerate) (PHBV) matrix to decrease the overall cost and to propose an alternative to non-biodegradable fossil-based materials. The objective of the present work was to investigate how the incorporation of vine shoots fillers and a preliminary polyphenol extraction step could impact the biodegradability of biocomposites. Biocomposites (20 wt %) were produced by microcompounding. The biodegradation of materials was assessed by respirometric tests in soil. The negative impact of polyphenols on the biodegradability of vine shoots was confirmed. This was supported by crystallinity measurements and scanning electron microscopy (SEM) observations, which showed no difference in structure nor morphology between virgin and exhausted vine shoots particles. The incorporation of vine shoots fillers in PHBV slightly accelerated the overall biodegradation kinetics. All the biocomposites produced were considered fully biodegradable according to the French and European standard NF EN 17033, allowing the conclusion that up-cycling vine shoots for the production of lignocellulosic fillers is a promising strategy to provide biodegradable materials in natural conditions. Moreover, in a biorefinery context, polyphenol extraction from vine shoots has the advantage of improving their biodegradability.

We found high intrapopulation variability through the wild populations that make it hard to differentiate them only on the base of morphology. We analyzed the biochemical profile of those populations based on the analysis of freeze-dried samples of leaves and stems. We identified and quantified twelve different phenolic compounds by the HPLC-diode array detector (DAD) technique. Six phenolic acids and flavonoids were identified in the leaves and stems of the wild and cultivated populations. Sinapic acid and myricetin are the majors identified compounds through our samples. The results were significantly different in relation to the plant organs and to the geographic origin for most of the compounds.

The content of the main water-soluble antioxidants (phenolics, ascorbic acid, and total biothiols) and the in vitro antioxidant potential (1,1-diphenyl-2-picrylhydrazil (DPPH) and superoxide anion scavenging capacity) were investigated. A total of 28 polyphenolic compounds were identified by LC/MS and quantitated by HPLC/DAD analysis. Kaempferol and quercetin derivatives were the most abundant phenolics compared to hydroxycinnamoyl gentiobiosides. In the ten populations, phenolics ranged from 163.9 to 533.9 mg/100 g dry weight (d.w.), ascorbic acid from 7.6 to 375.8 mg/100 g d.w., and total biothiols from 0.59 to 5.13 mg/100 g d.w. The different classes of phytochemicals were separated using solid-phase extraction at increasing methanol concentrations, and the antioxidant power of fractionated extracts was evaluated. The superoxide anion scavenging activity was significantly correlated to phenolics, particularly to flavonol derivatives, while DPPH was mainly related to ascorbic acid content. The present findings improve the knowledge of the phytochemical composition of Italian Brassica wild species by showing the great diversity of phytochemicals among populations and highlighting their importance as a valuable genetic resource for developing new cultivars with improved bioactive content.

Introduced, invasive plants can alter local soil chemistry and microbial communities, but the underlying mechanisms and extent of these changes are largely unknown. Based on characteristics associated with invasiveness in plants, it was hypothesized that introduced species that produce large amounts of litter with distinctive secondary compounds can a) alter the chemistry of both extractable and bulk carbon in the soil, b) shift microbial communities towards microbes better able to metabolize the compounds in the litter, and c) cause soil carbon chemistry and microbial communities to shift to relatively uniform, novel states at multiple sites. 2. Composition of phenolics in senescent tissues (leaves and roots) of Polygonum cuspidatum was compared to the composition of extractable phenolics and non-extractable bulk organic carbon in soils under and adjacent to large, long-established stands of P. cuspidatum at four sites in the eastern U.S. Rates of degradation of phenolics, activities of enzymes associated with the breakdown of phenolics, and shifts in microbial community composition were also measured at the sites. 3. Soils under P. cuspidatum stands contained twice as much phenolics as adjacent soils, but the composition of phenolics differed greatly between soils under stands and senescent tissues of P. cuspidatum. Flavonoids and proanthocyanidins constituted >90% of the identified phenolics in P. cuspidatum tissues, whereas monophenolic compounds accounted for > 90% of the phenolics in soils under stands. Soils under and adjacent to stands also exhibited distinctive compositions of relatively persistent bulk organic carbon; composition differed less between soils under stands at different sites than between soils under and adjacent to stands at the same site. 4. Soils under P. cuspidatum had 2.8 times greater abundance of fungi than soils adjacent to stands, and fungal markers showed clear separation of soils under and adjacent to P. cuspidatum. However, the potential activity of enzymes that degrade polyphenols was lower in soils under stands. Exogenously applied chemically complex polyphenols persisted in both P. cuspidatum invaded and adjacent non-invaded soils, whereas less complex compounds rapidly disappeared from both soils. 5. Synthesis. Results suggest that interactions between plant inputs, abiotic reactions, and biotic transformations may create and maintain new states in invaded soils that are chemically and biologically less diverse. In the case of polyphenol rich, fast growing invasive species, these interactions may alter the composition of bulk soil organic matter that has slower turnover rates, resulting in legacy effects. Restoration could thus require, not just removal of the species, but also post-removal interventions such as soil amendments.", "keywords": ["Flavonoids", "Peroxidases", "Mass spectrometry", "tannins", "Fallopia japonica", "Japanese knotweed", "Reynoutria japonica", "Polyphenols", "home-field advantage", "Legacy effect", "15.

In this work, a factorial field experiment was established, where three climatic treatments (W, warming; D, drought; W\u00a0+\u00a0D, warming + drought), mimicking future climate change scenarios were installed over five years in a Mediterranean savannah 'dehesa', accounting for its landscape diversity (under the tree canopy and in open grassland). A combination of analytical pyrolysis (Py-GC/MS) and the study of biogeochemical proxies based on lignin monomers is used for the direct detection of lignin-derived phenols and to infer possible shifts in lignin dynamics in soil. A total of 27 main lignin-derived methoxyphenols were identified, exhibiting different patterns and proportions, mainly driven by the effect of habitat, hence biomass inputs to SOM. An accelerated decomposition of lignin moieties -(exhibited by higher LG/LS and Al/K\u00a0+\u00a0Ac ratios)- is particularly exacerbated by the effect of all climatic treatments. There is also an overall effect on increasing lignin oxidation of side chain in syringyl units, especially under the tree canopy due to the alteration in biomass degradation and potential stimulation of enzyme activities. Conversely, in open grassland these effects are slower since the microbial community is expected to be already adapted to harsher conditions.

The rice conventional cropping system exhibited greater protein, lipids, and ash levels, and a head rice yield. However, organic rice presented greater total carbohydrates, soluble protein, amylose content, 33% greater free phenolics, and phenolic acids, but exhibited a greater percentage of stained grains during the storage period. The free phenolic content of cooked rice was lower than the free phenolic content of the raw rice. By Liquid chromatography with mass spectrometer (LC\uffe2\uff80\uff90MS) were identified p \uffe2\uff80\uff90coumaric and ferulic acids in both fractions (free and bound). The content of p \uffe2\uff80\uff90coumaric acid and ferulic acid in bound fraction was higher in organic brown rice than in conventional brown rice. At 6 and 12 mo of storage, the main fungi found were Aspergillus sp . and Penicillium sp . Prior to storage, the Bipolaris sp . fungi was identified only in organic rice. For conventional rice, the infestation level by Aspergillus sp. increased from 3% to 70% at the 6th mo of storage. In addition to the advantage of organic rice being free of agrochemicals, this study revealed that natural plant defense compounds could be produced when the rice was subjected to more biotic and abiotic stresses. However, some disadvantages were observed, such as lower protein content and a greater percentage of soluble protein, which favored the breaking of rice in processing, and a greater percentage of grain stained before and during storage.
Practical ApplicationThe organic and conventional cropping systems affect the physicochemical and technological properties of rice grains, which is one of the main cereals grown and consumed in the world. This study shows the advantages and disadvantages of the cropping system in grain properties that are in the interest of both consumers and processing industries.

In this regard, properties such as the antioxidant ability to extend food shelf life and light resistance, are of great interest in the production of packaging and mulching films, respectively. These features are obtained by developing blends with pure chemicals and/or natural products as additives. In the present work blend formulations of PLA/PBAT with a walnut shell extract rich in antioxidants were developed and evaluated for their properties in comparison with classic PLA/PBAT. Specifically, natural additives, and most importantly the production process were purposely selected to i) be green and cost-effective; ii) confer antioxidant properties; and iii) improve material performance. To this aim, a walnut shell extract (EWS) with high antioxidant activity was obtained thanks to a novel green and cost-effective microwave-assisted extraction (MAE) procedure. A response surface methodology was utilized to explore how the total phenolic content (TPC) and antioxidant activity are influenced by varying aqueous ethanol concentration, extraction time, and microwave power. The highest predicted TPC and antioxidant activity were achieved when employing the ideal conditions for Microwave-Assisted Extraction (MAE): using a mixture of 30\u00a0% ethanol in water, an irradiation time of 120\u00a0s, and a microwave power of 670\u00a0W. The optimized EWS was characterized by HPLC-MS determining qualitative and quantitative data with the identification of flavonoids, fatty acids, and anacardic acids among the main components, responsible for antioxidant activity. The resulting EWS powder was melt-mixed at 140C\u00b0 and 20 RPM with the bio-based PLA/PBAT bioplastic at two different concentrations (0.5 and 1.5 w/w) by forming film specimens. All EWS-based bioplastic films showed increased antioxidant features determined by the DPPH bleaching test, TEAC, and ORAC assays.

Colorimetric analyses of antioxidant compounds (total phenolics and flavonoids) and antioxidant capacity tests (DPPH, FRAP, ABTS) were carried out, and intact aliphatic and indolic glucosinolates (predominant aliphatic glucocapparin) were analyzed by HPLC-DAD method.

Likewise, the highest TFC was recorded in the non-gypsum soil leaves and the lowest in the non-gypsum soil seeds by 401.06 and 55.61 Qu mg/kg FW, respectively. The highest and lowest FRAP values were observed in the leaves in gypsum (0.94) and the pistils in gypsum soil (0.80), respectively. Regarding ABTS values, the flags in the non-gypsum and gypsum sites showed the highest and lowest values of 89.51 and 78.40%, respectively. High DPPH values were recorded for most parts.

Our results supported the potential of caper bush (C. spinosa) as a underexploited food rich in bioactivephytochemicals adapted to harsh soil conditions, with the potential for implementation in agroecosystems with adverse environmental conditions with the potential of better adaptation for securing the access to plant-derived foods.", "keywords": ["Flavonoids", "Science", "Q", "Phytochemicals", "Glucosinolates", "R", "Iran", "Gypsum soil", "Adaptation", " Physiological", "Calcium Sulfate", "Article", "Antioxidants", "Antioxidant capacity", "Soil", "Capparis", "Phenols", "Caper Bush", "Medicine", "Reducing capacity"]}, "links": [{"href": "https://doi.org/PMC11977014"}, {"rel": "related", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/Scientific%20Reports", "name": "related record", "description": "related record", "type": "application/json"}, {"rel": "self", "type": "application/geo+json", "title": "PMC11977014", "name": "item", "description": "PMC11977014", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/PMC11977014"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2025-04-07T00:00:00Z"}}], "links": [{"rel": "self", "type": "application/geo+json", "title": "This document as GeoJSON", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=Phenols&f=json", "hreflang": "en-US"}, {"rel": "alternate", "type": "text/html", "title": "This document as HTML", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=Phenols&f=html", "hreflang": "en-US"}, {"rel": "collection", "type": "application/json", "title": "Collection URL", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main", "hreflang": "en-US"}, {"type": "application/geo+json", "rel": "first", "title": "items (first)", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=Phenols&", "hreflang": "en-US"}, {"rel": "last", "type": "application/geo+json", "title": "items (last)", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=Phenols&offset=27", "hreflang": "en-US"}], "numberMatched": 27, "numberReturned": 27, "distributedFeatures": [], "timeStamp": "2026-07-26T16:57:21.137547Z"}
