Abstract: 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, Glu-B3, 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.
