It was hypothesized that cultivar mixtures may increase yields over a monoculture if disease pressure or nitrogen (N) availability is affected by the previous cover crop. The monoculture (1-cv) of the grower\u2019s preferred cultivar was compared with mixtures of it and other high-yielding cultivars in the region. Soil nitrogen, soil microbial biomass carbon (MBC), soil emissions of carbon dioxide (CO2) and nitrous oxide (N2O), crop nutrient uptake, biomass, fruit quality, intercepted photosynthetically active radiation (PAR), and disease symptoms were measured. The MCC reduced soil N leaching potential during winter and immobilized soil N early in the tomato season as suggested by higher soil MBC and CO2 emissions. Tomatoes had higher PAR, aboveground biomass, fruit yields, and harvest index in the winter fallow than in the winter MCC, likely due to higher N availability in the fallow plots after transplanting. All cultivar mixtures had fairly similar yield and shoot biomass within fallow and MCC, probably explained by the low genetic diversity among California modern tomato cultivars. However, at mid-season (75\u00a0days after planting (DAP)), the 3-cv mixture had higher shoot and fruit biomass, by 46% and 63%, than the monoculture in the MCC, indicating some plasticity under lower N availability. In the fallow treatment, soil CO2 emissions were lower in the 3-cv mixture than the monoculture at 77 and 100 DAP. Tomatoes in the 3-cv mixture were redder than the monoculture. The 3-cv mixture thus had some minor advantages compared with the monoculture, but overall, there was little evidence of higher ecosystem functions from mixtures vs. monoculture. Further research on mixtures of processing tomatoes may only be warranted for conditions of higher environmental stress than occur in California organic farms or if specific genotypic traits become available such as for disease resistance or improved nutrient uptake.", "keywords": ["Life Sciences", " general", "0106 biological sciences", "2.

The grafting is a vegetative multiplication method that induces or improves some qualities of the plants (vigor, resistance to soil diseases and pests, resistance to abiotic factors, quantity and quality of fruit production). The research aim has been to establish the technological stages for producing of Dutch scion and Romanian rootstock seedlings from Solanum lycopersicum L. species, to obtain some compatible phenotypes for grafting. This research has been conducted in a greenhouse of the Horting Institute Bucharest. The experience was carried out on a tomato cultivar collection consisting from a Dutch scion (\uffe2\uff80\uff98Abellus\uffe2\uff80\uff99 F1 hybrid) and three Romanian rootstocks (\uffe2\uff80\uff98L542\uffe2\uff80\uff99, \uffe2\uff80\uff98L543\uffe2\uff80\uff99, \uffe2\uff80\uff98L544\uffe2\uff80\uff99). The scion and rootstock diameters have been correlated for manual grafting, cutting at 45 degrees and using the method of splice in silicone tube. The technological stages for obtaining grafted tomatoes have been established for the researched genotypes. These tomato combinations have been compatible for vegetable crops in protected spaces in the south area of Romania.</p>", "keywords": ["2.

However, studies on the effect of AMF on viral infection, still limited and not conclusive, indicate that AMF colonization may have a detrimental effect on plant defenses against viruses, so that the term \uffe2\uff80\uff9cmycorrhiza-induced susceptibility\uffe2\uff80\uff9d (MIS) has been proposed for these cases. To expand the case studies to a not yet tested viral family, that is, Bromoviridae, we investigated the effect of the colonization by the AMF Funneliformis mosseae on cucumber mosaic virus (CMV) infection in tomato by phenotypic, physiological, biochemical, and transcriptional analyses. Our results showed that the establishment of a functional AM symbiosis is able to limit symptoms development. Physiological and transcriptomic data highlighted that AMF mitigates the drastic downregulation of photosynthesis-related genes and the reduction of photosynthetic CO2 assimilation rate caused by CMV infection. In parallel, an increase of salicylic acid level and a modulation of reactive oxygen species (ROS)-related genes, toward a limitation of ROS accumulation, was specifically observed in CMV-infected mycorrhizal plants. Overall, our data indicate that the AM symbiosis influences the development of CMV infection in tomato plants and exerts a priming effect able to enhance tolerance to viral infection.</p>", "keywords": ["0301 basic medicine", "plant\u2013virus interaction", "arbuscular mycorrhizal symbiosis", "Microbiology", "Cucumovirus", "Plant Roots", "Article", "03 medical and health sciences", "Solanum lycopersicum", "Gene Expression Regulation", " Plant", "Mycorrhizae", "arbuscular mycorrhizal symbiosis", " cucumber mosaic virus", " Funneliformis mosseae", " gene expression", " priming tolerance", " plant-virus interaction", " RNA sequencing", " Solanum lycopersicum L.", "Photosynthesis", "Symbiosis", "<i>Funneliformis mosseae</i>", "Plant Diseases", "2.
