attempt to elucidate the origin of cultivated soybean via comparison of nucleotide sequences encoding glycinin B4 polypeptide of cultivated soybean, Glycine max, and its presumed wild progenitor, Glycine soja

Nucleotide sequences of cDNAs encoding soybean glycinin B4 polypeptide were compared for three soybean cultivars and two introductions of wild soybean, G. soja. For three G. max cultivars, only two nucleotide substitutions were found, while G. max and G. soja nucleotide sequences had four substituti...

Summary:Nucleotide sequences of cDNAs encoding soybean glycinin B4 polypeptide were compared for three soybean cultivars and two introductions of wild soybean, G. soja. For three G. max cultivars, only two nucleotide substitutions were found, while G. max and G. soja nucleotide sequences had four substitutions. These data give added proof that G. max originated from G. soja. On the other hand, the time required for the accumulation of four nucleotide substitutions (calculated from the parameters of 11S globulin molecular evolution) appeared to be longer than the duration of the soybean domestication period.
