Study of interactions between wild soybean subpopulations (Glycine soja) in the valley of the Tsukanovka river in the south of Russia’s Far East

Comparative analysis of the genetic structure of natural and anthropogenic populations of G. soja gives significant information about the formation of different populations and allows for the developing of measures for the preservation of the unique natural gene bank of wild soybean, which is a species closely related to cultivated soybean. In this study, ISSR-markers were used to carry out a comparative analysis of the genetic structure of natural and anthropogenic subpopulations of G. soja for studying the possible mutual influence of subpopulations of anthropogenic and natural phytocenosis on the formation of their genetic diversity and studying the genetic structure of natural subpopulations of wild soybean in the contact places between the two types of cenoses. As a result, the characteristics that describe the genetic diversity of the studied populations have been identified, and the important role of interaction between subpopulations of different phytocenoses in the formation of the spatial genetic structure of the population in the Tsukanovka river valley have been demonstrated.
