摘　　要：小麦是我国主要的粮食作物之一,籽粒中的低分子量麦谷蛋白对于小麦面包的加工品质具有重要的作用。近年来,利用分子标记技术检测小麦低分子量麦谷蛋白亚基(low molecular weight glutenin subunit,LMW-GS)的类型和组成已成为小麦品质改良的研究热点之一。主要综述了小麦低分子量麦谷蛋白亚基基因和蛋白质的结构特征、分类以及功能标记的研究进展,讨论了开发利用小麦Glu-A3、Glu-B3、Glu-D3位点LMW-GS功能标记的意义及存在的问题,并强调了LMW-GS分子标记检测技术的革新及亚基类型的完善对小麦品质改良的重要性,以期加速LMW-GS功能标记在优质小麦育种工作中的应用进程。Wheat is one of the major grain crops in China. Low molecular weight glutenin subunit（ LMW-GS） plays a crucial role in determining the unique baking quality of wheat. In recent years,detecting the type and composition of LMW-GS by molecular markers technique has become one of the hotspots in the study of wheat quality improvement. The latest research progress on the structure of LMW-GS gene and protein,and its classification and functional markers were summarized in this paper,and then the significance of exploitation and utilization as well as the existing problems of the LMW-GS functional markers for the Glu-A3,GluB3,Glu-D3 loci in wheat were also discussed. Finally,it was pointed out that the importance of innovation of LMW-GS marker technology and supplement of subunit types to the improvement of wheat quality,which was expected to accelerate the application of LMW-GS functional markers in wheat breeding with high quality.
