“…The results obtained suggest that (1) genetically different groups of wild soybean have active development, (2) level of polymorphism was significantly higher than in the cultivated soybean and (3) geographically isolated subpopulations showed maximum distance from the main population of wild soybean. The high level of polymorphism between the wild and cultivated soybean accessions was also reported by Kanazawa et al (1998) in their study on soybean accessions from the Far East using RAPD profiles of mitochondrial and chloroplast DNA. Xu & Gai (2003), Pham Thi Be Tu et al (2003, confirmed the results of Kanazawa et al (1998) and Seitova et al (2004) in terms of the high genetic variation between the wild and cultivated soybean accessions.…”

They also found that the diversity of G. soja was higher than that of G. max; and environmental factors may play important roles in soybean evolution.…”

Evolutionary changes in the structures of the cox2 and atp6 loci in the mitochondrial genome of soybean involving recombination across small interspersed sequences

et al. 1998

Mitochondrial DNA (mtDNA) fragments that contained cox2 or atp6 loci were cloned from three accessions of wild soybean (Glycine soja) in order to understand the evolutionary changes of mitochondrial genomes in the genus Glycine subgenus Soja. Cox2 was cloned as a single configuration, while atp6 was cloned as either one or two configurations from each accession. Structural variations were detected in the 5' upstream region of cox2 and in both the 5' upstream and 3' downstream regions of atp6. These variations appeared to be the results of recombination events. A comparison of the mtDNA fragments previously cloned from a cultivated soybean (G. max) and a wild soybean revealed various sites of recombination, as well as various combinations of the 5' and 3' regions, at the cox2 and atp6 loci. Some of the cloned fragments were found to contain a set of repeated sequences, namely 299-bp and 23-bp repeats in the 5' region of cox2 or atp6, which were interspersed in the mitochondrial genome in the subgenus Soja. Recombination events involving the 299-bp or 23-bp repeated sequences were shown to account for the generation of structural variations in the 5' regions of these loci.

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
