大豆籽粒蛋白代谢途径及相关调控机制研究进展

Research Progress on Metabolic Pathways of Seed Protein and Related Regulation Mechanism in Soybean

氮是大豆生长发育不可缺少的一种元素,主要通过大豆根部-根瘤体系等一系列途径转化为籽粒蛋白。大豆籽粒蛋白含量远高于其它作物,因其独特的营养价值和保健功能被广泛应用。本文介绍了大豆籽粒蛋白的特性和分类、综述了其主要代谢途径和调控机制等方面的研究进展,并提出以高蛋白大豆为主要育种目标的有效途径,以期为大豆的营养改良提供参考。

Nitrogen is an indispensable nutrient for soybean. The nitrogen in the air can be transformed to protein in seed through Root-Rhizoma system and various pathway. Soybeans is an important food because of its nutritional qualities and func-tional properties, which contain considerably more protein content than other crops. This paper summarizes publications on the characteristics and classifications of soybean protein, discusses research progress of protein metabolism pathway and regulation mechanism in soybean. And we addressed effective way of breeding for high protein content soybean, which can provide the reference for soybean quality improvement.
