Abstract
Changes in the structural diversity of bacterial communities in soybean rhizospheres play important roles in plant growth and crop productivity. However, there are only a few studies on different soybean growth stages. Here, we investigated the changes in the bacterial community of soybean rhizosphere soil at two stages using Illumina high-throughput sequencing. The results showed that the bacterial abundance and diversity in the seeding stage were higher than those in the mature stage and that the diversity changed significantly. Actinobacteria, Acidobacteria, and Proteobacteria were the dominant bacteria in the soybean rhizosphere soil. Additionally, changes in Actinobacteria and Proteobacteria abundances showed opposite trends.
