Genetic diversity and its geographical patterns play a very important role in species conservation and exploitation. Here, nucleotide polymorphism patterns of four single copy nuclear gene loci in wild ( Glycine soja ) and cultivated soybean ( Glycine max ) populations from different geographical regions as well as their demographic history were analyzed. The results showed that: (1) Southern subpopulation has the highest, while central subpopulation revealed the lowest genetic diversity among three Chinese G . soja subpopulations. (2) Northern Chinese G . max subpopulation depicted higher genetic diversity than other two Chinese, Korean, Japanese and American G . max subpopulations. (3) Significant genetic differentiation ( P < 0.001) was observed among Chinese G . soja subpopulations from three ecological zones. There was also a significant genetic differentiation（ P < 0.01）between three Chinese and Japanese subpopulations of G . max . (4) The demographic dynamics revealed that effective population size of G . soja is expanding, while it was constant in G . max . G . soja is a useful germplasm resource to widen the genetic diversity of G . max . This study suggests that native populations of G . soja from different geo-ecological regions should be protected to conserve the genetic diversity. [ABSTRACT FROM AUTHOR]
