Yic. Hsing et al., THE RELATIONSHIPS OF CULTIVATED SOYBEANS AND THEIR WILD RELATIVES COLLECTED FROM TAIWAN - REVEALED BY SEED PROTEINS, Zhongyang yanjiuyuan. zhiwuxue huikan, 36(2), 1995, pp. 65-72
We conducted molecular studies of the taxonomic relationships between
cultivated soybean, Glycine max, and its wild relatives, G. soja, G. t
omentella, and G. tabacina, collected in Taiwan and the nearby islands
. The G. max and G. soja are annual and the others are perennial. We u
sed protein gels and Western blot to study their seed proteins-includi
ng two major storage proteins, lectin, and several seed maturation pro
teins. We performed RFLP analysis using soybean seed maturation protei
n cDNA clones as the probes. The data were used to assess the degree o
f genetic variability and similarity existing between and within diffe
rent species of Glycine collected in Taiwan. The results confirm and e
xtend the present model of the taxonomic relationships. Seed maturatio
n proteins may serve as a marker that reveals relationships between th
e member species of the Glycine taxon.
