title: Do soybeans select specific species of Bradyrhizobium during growth?
abstract: Soybean is an important crop, with processed soybeans being the second largest source of vegetable oil and the largest source of animal protein feed in the world. Nodules on soybean roots are responsible for symbiotic nitrogen fixation, enabling soybean plants to obtain sufficient nitrogen for growth and seed production. Because nitrogen is an essential, but often limiting, nutrient for plant growth, improvements in nitrogen fixation are highly required in agriculture. We recently reported a comprehensive analysis of rhizosphere bacterial communities during soybean growth in a field in Kyoto prefecture, Japan. The bacterial communities of the rhizosphere changed significantly during growth, with potential plant growth-promoting rhizobacteria, including Bacillus, Bradyrhizobium, and Rhizobium, increasing in a stage-specific manner. In this addendum, we focus on changes in Bradyrhizobium during soybean growth, suggesting that soybean plants select for symbiotic partners.
