Study Shows Impact of GM Soybeans on the Structure of Rhizosphere Soil Microbial Communities
February 5, 2025| |
A study conducted by researchers from the Ministry of Ecology and Environment, Nanjing China showed that the cultivation of genetically modified (GM) soybean did not alter the overall structure of rhizosphere soil microbial communities.
High-throughput sequencing revealed that, while GM soybeans slightly altered bacterial and fungal composition, these changes were insignificant across all growth stages. While GM soybean rhizosphere soil showed a higher bacterial Shannon index during flowering, the analysis showed that there were no significant differences in community structure between GM and non-GM soybeans.
The research also revealed that major functional microbial groups remained stable, and the number of root nodules in GM soybeans was unaffected, with no significant impact on nitrogen-fixing bacteria throughout the growing stage. However, the authors suggest continuous monitoring of the abundance and ecological functions of Bradyrhizobium, Frankia, and Thelebolus.
