Abstract: | Glycosyltransferases are members of the multigene superfamily in plants that can transfer single or multiple activated sugars
to a range of plant molecules, resulting in the glycosylation of plant compounds. Although the activities of many glycosyltransferases
and their products have been recognized for a long time, only in recent years were some glycosyltransferase genes identified
and a few functionally characterized in detail. Glycosylation is thought to be one of the most important modification reactions
towards plant secondary metabolites, and plays a key role in maintaining cell homeostasis, thus likely participating in the
regulation of plant growth, development and in defense responses to stress environments. With advances in plant genome projects
and the development of novel technologies in analyzing gene function, significant progress could be made in gaining new insights
into the properties and precise biological roles of plant secondary product glycosyltransferases, and the new knowledge will
have extensive application prospects in the catalytic synthesis of glycoconjugates and metabolic engineering of crops. In
this review, we summarize the current research, highlighting the possible biological roles, of plant secondary metabolite
glycosyltransferases and discuss their potential applications as well as aspects to be further studied in the near future. |
