摘要: Grape (Vitis vinifera) accumulates various polyphenolic compounds, which protect against environmental stresses, including ultraviolet-C (UV-C) light and pathogens. In this study, we looked at the transcriptome metabolome in grape berry skin after UV-C irradiation, demonstrated effectiveness of omics approaches to clarify important traits grape. We performed analysis using a genome-wide microarray, revealed 238 genes up-regulated more than 5-fold by light. Enrichment Gene Ontology terms showed that encoding stilbene synthase, key enzyme for resveratrol synthesis, were enriched genes. liquid chromatography-quadrupole time-of-flight mass spectrometry, 2,012 metabolite peaks, unidentified detected. Principal component peaks only one peak, identified as resveratrol, was highly induced updated metabolic pathway map Kyoto Encyclopedia Genes Genomes (KEGG) database KaPPA-View 4 KEGG system, then projected data on map. The specific induction synthetic Our results multiomics is powerful tool elucidate accumulation mechanisms secondary metabolites, systems, such grape, can support studies.
