Abstract
UGT (uridine diphosphate glycos-yltransferase) is involved in the process of glycosylation modification and plays an important role in plant growth and development, secondary metabolism and stress response. The aim of this study was to investigate the role of UGT in the biosynthesis of grape secondary metabolites based on the genome-wide identification of grape UGT gene family. Gene family identification, bioinformatics analysis, gene mapping, phylogenetic tree analysis, conservative motif prediction, gene structure and cis-element analysis were performed by using the software. Combined with transcriptome data and KEGG enrichment analysis, genes related to secondary metabolic processes were screened. We identified 181 UGT genes in the grape genome and divided them into 18 subfamilies. Comprehensive analysis showed that fragment duplication events had significant effects on the evolution of VvUGT gene family, and the motif distribution of proteins in the same subfamily was similar Developmental, hormonal, and stress-related cis-elements are enriched in the promoter region. We identified 14 genes in the VvUGT family that may be involved in anthocyanin synthesis. These results provide a theoretical basis for further study on the mechanism of VvUGT gene family regulating the synthesis of plant secondary metabolites.
