Research Advances in UDP-Glycosyltransferases of Ornamental Plants
Glycosylation modification plays a crucial role in the growth and development of plants.The core enzyme that catalyzes the synthesis of glycosylation products is glycosyltransferase(GT),which includes the UGT family members.The UGT family primarily utilizes uridine diphosphate(UDP)as the glycosyl donor.Plant glycosylation reactions play a crucial role in regulating the solubility,stability and bioactivity of various plant metabolites.Furthermore,they are closely associated with plant quality traits,the storage of volatile compounds and respond to abiotic and biotic stresses.This study reviews the structural and catalytic features,reaction types,and functional classifications of glycosyltransferases in ornamental plants.It summarizes current research progress on modifications of hormones,terpenoids,and flavonoids in ornamental plants via UDP-glycosyltransferases,eventually affecting flower color,leaf color,leaf morphology,plant adversity,and functional compounds.By reviewing and summarizing the relevant studies,this study will help to understand the role of glycosyltransferases in the metabolic regulation of ornamental plants.Furthermore,this will also lay a foundation for future innovation in ornamental plant germplasm improvement and the development of functional components.
