Inheritance 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 کاملbeta-Conglycinin and glycinin in high-protein soybean seeds.
The agronomic performance and storage proteins of high seed protein lines of soybeans [Glycine max L. (Merr.)] were investigated to determine if the two major storage proteins, beta-conglycinin and glycinin, contribute to the increased protein content of high seed protein lines. Subunits of these two major storage proteins were estimated by scanning SDS-PAGE gels by scanning densitometry. The r...
متن کاملGlycinin composition of several perennial species related to soybean.
The 7S and 11S seed storage proteins from four perennials related to soybean (Glycine canescens, G. tomentella, G. tabacina, and G. clandestina) were analyzed by sodium dodecyl sulfate-gel electrophoresis. Each species yielded a unique electrophoretic pattern that varied in the total number of bands and their relative mobilities. In every case, the electrophoretic patterns were substantially di...
متن کاملCrystal structure of soybean 11S globulin: glycinin A3B4 homohexamer.
Most plant seeds contain 11S globulins as major storage proteins for their nutrition. Soybean glycinin belongs to the 11S globulin family and consists of five kinds of subunits. We determined the crystal structure of a homohexamer of the glycinin A3B4 subunit at 2.1-A resolution. The crystal structure shows that the hexamer has 32-point group symmetry formed by face-to-face stacking of two trim...
متن کاملCharacterization of the glycinin gene family in soybean.
We characterized the structure, organization, and expression of genes that encode the soybean glycinins, a family of storage proteins synthesized exclusively in seeds during embryogenesis. Five genes encode the predominant glycinin subunits found in soybeans, and they have each been cloned, sequenced, and compared. The five genes have diverged into two subfamilies that are designated as Group-I...
