Abstract

Abstract:

As one of the main products of photosynthesis,sucrose has a variety of physiological functions in plants.As a group of glycosyltransferase enzymes,sucrose synthase plays an important role in the process of sucrose metabolism.In plants,sucrose synthase reversibly catalyzes the decomposition of sucrose and nucleoside diphosphate(NDP)to produce nucleoside diphosphate glucose(NDPG)and fructose.This reaction is the most important rate-limiting step in sugar metabolism.Sucrose synthase exists in the form of a gene family in plants.Phylogeny shows that there are three subgroups of sucrose synthase,and different subgroups have different expression patterns.Recent studies have shown that sucrose synthase has several major physiological functions in plants,such as participating in the synthesis of macromolecular sugars,response to adversity,participating in reproductive growth and regulating fruit quality.This article reviews the research progress of sucrose synthase in recent years,and looks forward to future research directions in order to provide a reference for future research.
