Abstract:

Sweetness is an important aspect of vegetable soybean, and it is one of the distinguishing characteristics of vegetable soybean from ordinary grain-type soybean. It is generally believed that the sweetness of vegetable soybean is mainly attributed to the soluble sugar content. Sucrose accounts for 71% of the total soluble sugar, which is the key factor determining the sweetness and taste quality score of vegetable soybean. Understanding the genetic and regulatory mechanism of sucrose in vegetable soybean seeds is of great significance for accelerating the genetic improvement of taste quality and enhancing the competitiveness of Chinese vegetable soybean in the international market. This article reviewed the research progress on the metabolism and regulation of sucrose in vegetable soybean grains, mainly on the genetic mechanism of soybean sucrose content, the regulation mechanism of key enzymes in the process of sucrose metabolism and the cloning of their homologous genes. Finally, the future research directions and goals of vegetable soybean sucrose content were prospected in order to provide reference for improving the eating quality of vegetable soybean.

Key words: soybean [Glycine max(L.) Merri.], sucrose content, taste quality, genetic basis, metabolic regulation
