Abstract

The nucleotide sequences of four intergenic spacer regions of chloroplast DNA, atpB-rbcL, trnS-trnG, rps11-rpl36, and rps3-rpl16, were analyzed in the genus Glycine. Phylogenetic analysis based on the sequence data using Neonotonia wightii as the outgroup generated trees supporting the classification of two subgenera, Soja and Glycine, and three plastome groups in the subgenus Glycine. The results were consistent with the presence of diversified chloroplast genomes within tetraploid plants of G. tabacina and G. tomentella, as well as with a close relationship between G. tomentella and G. dolichocarpa that had been suggested based on morphological analyses. Little sequence variation was found in the subgenus Soja, suggesting that G. soja rapidly expanded its distribution in East Asia. The analysis also showed that the differentiation into three plastome groups in the subgenus Glycine occurred in the early stages of its evolution, after the two subgenera diverged.
