BackgroundPomelo is one of the three major species of citrus. The fruit accumulates a variety of abundant secondary metabolites that affect the flavor. UDP-glycosyltransferases (UGTs) are involved in the glycosylation of secondary metabolites.ResultsIn the present study, we performed a genome-wide analysis of pomeloUGTfamily, a total of 145 UGTs was identified based on the conserved plant secondary product glycosyltransferase (PSPG) motif. TheseUGTgenes were clustered into 16 major groups through phylogenetic analysis of these genes with other plant UGTs (A-P). Pomelo UGTs were distributed unevenly among the chromosomes. At least 10 intron insertion events were observed in theseUGTgenome sequences, and I-5 was identified to be the highest conserved one. The expression profile analysis of pomeloUGTgenes in different fruit tissues during development and ripening was carried out by RNA-seq.ConclusionsWe identified 145 UGTs in pomelo fruit through transcriptome data and citrus genome database. Our research provides available information on UGTs studies in pomelo, and provides an important research foundation for screening and identification of functionalUGTgenes.
