Clone And Study On Transforming Tobacco Of Glycinin Gy7 Gene

Soybean seeds are nutritive source of proteins to people or animals andalso fine natural resources used in improving nutritive qualities of major crops that areshort of proteins, for there are plentiful protein contents. The 11S glycinin is one ofthe most important components of storage proteins in soybean seeds. Six kinds offunctional glycinin were discovered, they are G1,G2,G3,G4,G5 and G7, codedby the corresponding genes of Gy1,Gy2,Gy3,Gy4,Gy5 and Gy7.This papersummarizes the studies on glycinin including components,structure and gene families.The homogeneity of the glycinin gene sequences was compared by bioinformatics.Heredity Distances of the six glycinin genes were analyzed. Special emphasis is laidupon comparing the sequences and components of amino acids in the glycinin. Thecontents of major amino acids in the intact glycinin and in the acid and basic peptideswere analyzed. In view of others and our researches, we advance some new thinkingand tactics of improving rice nutritional quality by using glycinin genes.
