Summary: Systems genetics uses comprehensive multi-omics data to decode complex traits by constructing context-specific regulatory networks and integrating them with genome-wide association studies (GWAS). SpecVar method improves heritability enrichment by associating SNPs with regulatory elements and prioritizes gene regulations underlying relevant tissues. Experimental validation shows that SpecVar enhances heritability enrichment, accurately detects relevant tissues, and reveals causal regulations. It also outperforms existing methods in revealing shared SNP-associated regulations of phenotypes.

Summary: This study investigated the impact of different parameters on the contents and dynamics of free amino acids (FAAs) in greengage wine. The results showed that higher glucose proportion, lower yeast inoculation, higher temperature, and higher initial pH led to increased total and essential amino acid (EAA) content. The optimum conditions for a 14.9-fold increase of EAAs in fermented greengage wine were found to be 22.4°C, pH 4.5, and 3% inoculation.

Summary: This study investigates the variation and genetic influence on the metabolite profiles of oats, specifically the seed metabolites with antioxidant properties. The research finds reduced genetic variation in modern oat germplasm compared to diverse germplasm, mainly due to increased seed size from intensive breeding. The abundance of avenanthramides, one of the specialized metabolites, increases with seed size, while avenacoside abundance decreases. The study highlights the importance of understanding how plant breeding influences plant traits and the genetic basis behind these changes.

Summary: Food production strategies and patterns are being altered in response to climate change. Enhancing the adaptation of important food crops to novel climate regimes will be critical to maintaining world food supplies. Climate change is altering the suitability of production areas for crops such as potato (Solanum tuberosum L.) making future productivity, resilience, and sustainability of this crop dependent on breeding for climate adaptation, including through the introgression of novel traits from its wild relatives. In doing so, researchers have developed a prioritization value system to locate potentially beneficial species possessing local adaptability, climatic plasticity, and interspecific crossability. The study found significant shifts in potato production areas by 2070 and varying degrees of climate overlap between potato and its wild relatives. This research highlights the importance of utilizing unique species with local adaptability to adapt potato to changing local climates.

Summary: In this study, we tested the applicability of genomic prediction methods based on biochemical pathways for oat seed metabolites. The results showed that metabolite kernels developed from the discovery panel significantly improved the prediction accuracy of the same metabolites in the validation panel. However, this method did not improve the prediction accuracy for GC-MS metabolites.

Summary: The tocopherol biosynthetic pathway in plants is encoded by VTE genes, but many quantitative trait loci for seed total tocopherols do not have VTE genes, suggesting other activities are involved. A study on Arabidopsis seed tocopherols found a significant interval without VTE genes, which mapped to an uncharacterized, seed-specific, envelope-localized, alpha/beta hydrolase. Mutations in AtVTE7 and its maize ortholog ZmVTE7 significantly decreased seed and leaf total tocopherols, while overexpression of these genes increased leaf totaltocopherols. These findings suggest a model where VTE7 releases prenyl alcohols from chlorophyll biosynthetic intermediates for tocopherol biosynthesis.

Summary: Grafting can improve melon fruit yield and quality, but lack of compatibility between rootstock and scion hampers its effect. We studied melon-pumpkin graft combinations with different compatibility levels to assess the impact of rootstock identity on melon fruit yield and quality. Our results showed that rootstock identity (and compatibility level with scion) was associated with increased fruit nutritional values, including high concentrations of organic acids and soluble carbohydrates.

Summary: A study on the petioles of perennial desert shrub Zygophyllum dumosum Boiss revealed a consistent seasonal pattern in petiole metabolism, involving organic acids, polyols, phenylpropanoids, sulfate conjugates, and piperazines. The metabolic changes were primarily related to the plant's development stage and its interaction with the environment, rather than specific environmental conditions.

Summary: Continuously increasing global temperature could have a significant impact on grape berry metabolite accumulation, wine polyphenol concentration, and color intensity. Field trials were conducted to explore the effect of late shoot pruning on grape berry and wine metabolite composition. The results showed that late pruning treatments had a significant effect on must and wine metabolites, with higher metabolite content observed in the late shoot pruning treatments for Syrah grapes, but not consistently for Malbec grapes. This suggests that late shoot pruning can impact must and wine quality-related metabolites, which may be related to enhanced photosynthetic efficiency, especially in warm climates.
