Genetic Variation and Relationships among Cultivated, Wild, and Semiwild Soybean

Fukuda (1933) proposed that G. gracilis is an intermediate evolutionary type between G. soja to G. max, but Some annual Glycine accessions are intermediate between the Hymowitz (1970) suggested that G. gracilis is a hybridstandard phenotypes of Glycine max (L.) Merr. and Glycine soja Sieb. & Zucc. and have been labeled semiwild. Few studies have ization product of G. max and G. soja. The latter...

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...

Glycinin 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...

Investigation of Genetic Variations among Crested Wheatgrass Species Base of Agronomical Traits and Total Leaf Protein

Genetic variations within the species of Agropyron desertorum and 2 varieties of A. cristatum subsp. pectinatum var. imbricatum and A. cristatum subsp. pectinatum var. pectinatum were studied using morphological traits and total protein profiles (with sodium dodecylsulphate polyacrylamide gel electrophoresis). An experiment was conducted in Research Institute of Forests and Rangelands (2012-201...
