Genome-wide characterization of the UDP-glycosyltransferases (UGT) family and functional analysis of VcUGT160 involved in dihydrozeatin glycosylation during blueberry fruits development.

ABSTRACT:

Background

Blueberry (Vaccinium spp.) celebrated for its rich nutritional content and significant health benefits, was referred to as the 'Queen of Fruits' and the 'King of Berries'. The development of blueberry fruits is closely related to plant hormones. Glycosylation mediated by UDP-glycosyltransferases (UGTs) is a key step in plant hormones homeostasis. However, the UGT members has not been reported in blueberry to date.

Results

A total of 361 VcUGT genes were identified and classified into 11 groups. Whole-genome and segmental duplications drove VcUGT expansion, with structural analysis revealing conservation within subgroups but divergence among them. Group G members were associated with cytokinin glycosylation, particularly dihydrozeatin, which promotes fruit enlargem
