physiological function
-
isoform UGT706D1 and UGT707A2 are the two major flavone UGTs responsible for glucosylation 7-OH and 5-OH groups of rice flavones, respectively. UGT706D1-overexpression plants display increased accumulation of flavone 7-O-glucosides and flavone 7-O-rutinoside. Flavone O-glucoside content correlates with UV-B tolerance. O-glycosylated flavones play a positive role in plant UV-B protection and flavone 5-O-glucosides are more effective UV-B protectants than flavone 7-O-glucosides
