植物糖基转移酶的分类、分布及在果实发育中作用研究进展

Classification and Distribution of Glycosyltransferases in Plant and its Roles in the Fruit Development

糖基转移酶是一种可以催化特定的糖基供体转移到受体分子,并形成糖苷键的活性蛋白质。其广泛存在于各种生物体中,特别是在植物的生长发育、开花结果等不同生命阶段中发挥不可或缺的作用。果实成熟是果实发育过程中品质形成的关键阶段。为了进一步探究糖基转移酶对果实软化、色泽、香气、风味等成熟品质的形成所产生的影响,文章概述了糖基转移酶在不同种类果实中的分类、分布及其在果实成熟过程中作用的研究进展,并对今后相关糖基转移酶的研究方向加以展望。通过进一步深入了解各类果实的成熟与品质形成机制,丰富果实成熟的调控网络,从而为水果的品质改变和采后贮藏、保鲜、加工提供重要的理论依据。

Glycosyltransferases are active protein that catalyze the transfer of specific glycosyl donors to acceptor molecules,which form glycosidic bonds.They can be found in a wide variety of organisms and play relatively important roles in different life stages of plants,such as growth and development,flowering and fruiting.Fruiting ripening is a key stage in fruit quality formation.In order to further explore the effect of glycosyltransferases on the formation of fruit qualities,such as softening,color,aroma and flavor,the paper reviewed the classification and distribution of glycosyltransferases in different kinds of fruit,as well as their roles in fruit ripening.The prospect for future research has also been discussed.Thus,it brings a deeper understanding of the ripening and quality formation mechanism of various types of fruits and provides a reference of changes in fruit quality,storage,preservation and processing.
