Genome-wide identification of the UGT genes family in Acer rubrum and role of ArUGT52 in anthocyanin biosynthesis under cold stress.

ABSTRACT: Acer rubrum is a widespread Acer species valued for its vibrant autumn foliage. The UGT (UDP-glycosyltransferase) gene family is integral to the biosynthesis of anthocyanins, the pigments responsible for leaf coloration. This study aimed to comprehensively identify and characterize the UGT gene family in the A. rubrum genome. The results of the phylogenetic analysis of 249 ArUGTs revealed 18 distinct subgroups. Conserved motif analysis demonstrated structural similarities within subgroups. Gene duplication analysis identified 21 tandem and 66 segmental duplication events across chromosomes. Transcriptomic data from autumn leaves of different colours and under low-temperature stress were analyzed for ArUGT expression patterns. Compared to controls, 44 UGTs were upregulated and 99 downregula
