Subgenome-Resolved Analysis and Regulatory Divergence of UDP-Glycosyltransferases in Allotetraploid Panax ginseng
Background: Polyploidization generates extensive gene redundancy, but how duplicated metabolic genes are retained and subsequently diversified remains poorly understood. UDP-glycosyltransferases (UGTs) provide a suitable system for examining this process because they participate in specialized metabolism, plant develop...
