Effects of Salt Stress on Root and Rhizosphere Fungal Communities of Wild Soybean
As a second-class nationally protected wild plant in China, the response mechanism of wild soybean to salt stress holds significant research value. In this study, hydroponic experiments with varying salt gradients were conducted, and high-throughput sequencing technology was employed to investigate the effects of salt stress on fungal communities in the roots and rhizosphere of wild soybean. The aim was to elucidate the reconfiguration rules of plant-fungal interactions under salt stress and to explore the development and utilization of beneficial microbial resources within its root and rhizosphere systems. The results indicated that the fungal communities in the roots (including the root system and rhizosphere) of wild soybean did not show substantial differences in biodiversity across different salinity levels. However, these communities could enhance adaptability to adverse conditions by restructuring their composition, thereby maintaining a relatively stable ecological system.
