Improvement of the Nutritional Value of Soybean [Glycine max (L) Merr.] Seed with Alteration in Protein Subunits of Glycinin (11S Globulin) and β-conglycinin (7S Globulin)
Protein quality in soybean seeds is strongly influenced by nutritional conditions. Glycinin (11S globulin) and β-conglycinin (7S globulin) are the 2 main proteins in soybean seeds. Protein quality of glycinin (11S) is higher than that of β-conglycinin (7S), due to the presence of higher amounts of s-containing amino acids (methionine and cysteine) in glycinin than β-conglycinin. Of the amino ac...
متن کاملSoybean [Glycine max (L.) Merr].
In this chapter we describe an Agrobacterium tumefaciens transformation method of soybean that utilizes mature half seeds and regeneration from the cotyledonary node region. This method results in fertile transformed soybean plants and transgenic seed in approximately 9 months. Using mature half seeds as starting material has proven to be a reliable method that does not require additional wound...
متن کاملInheritance and Organization of Glycinin Genes in Soybean.
Five genes (Gy1, through Gy5) encode most of the subunits that are assembled into glycinin, a predominant seed storage protein found in soybeans. Restriction fragment length polymorphisms are described that identify four of these five genes (Gy1/Gy2, Gy3, and Gy5). The fifth gene (Gy4) is characterized by two alleles, one of which (gy4) causes absence of the subunit. Genetic segregation studies...
متن کاملThe biosynthesis and processing of high molecular weight precursors of soybean glycinin subunits.
The predominant storage protein of soybean seed, glycinin, is composed of two heterogeneous classes of related subunits, the acidics (Mr approximately 38,000) and the basics (Mr approximately 22,000). Immunoreaction of polypeptides translated in vitro from isolated seed mRNA using antibodies prepared against either purified acidic or basic subunit groups precipitated precursor polypeptides of M...
متن کاملProteomic and genetic analysis of glycinin subunits of sixteen soybean genotypes.
We investigated proteomic and genomic profiles of glycinin, a family of major storage proteins in 16 different soybean genotypes consisting of four groups including wild soybean (Glycine soja), unimproved cultivated soybean landraces from Asia (G. max), ancestors of N. American soybean (G. max), and modern soybean (G. max) genotypes. We observed considerable variation in all five glycinin subun...
