Abstract—
The legume–rhizobia symbiosis is a unique natural phenomenon, which supplies the plant with the necessary mineral nitrogen via fixation of atmospheric dinitrogen. This interaction involves two partners: the legume plant and root nodule bacteria (rhizobia). In the wild, members of the Fabaceae family enter into symbiosis with a polymorphic group of rhizobia specific to them; the mechanism and reasons for the formation of heterogeneity of rhizobia are currently the subject of active research. In the present work, a Rhizobium leguminosarum strain strictly specific to Phaseolus vulgaris L. was used to show that within 30 days upon its introduction into soil, genetic rearrangements occurred in the cells, as was revealed by changes in the pattern of its genetic profile. It was also found that recombination activity of the cells was also affected by the root exudates produced during seed germination, which may indicate involvement of the plant in the formation of polymorphism of its microsymbionts. These findings suggest interpretation of this process not as a spontaneous event, but rather as an event controlled by the plant.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
