The Application Potential of the Rhizobacteria of the Native Leguminous Plants in the Arid Regions of China

Leguminous plants in arid regions are crucial for maintaining ecological balance and promoting sustainable agricultural development. The classification and characterization of the plant growth promoting rhizobacteria (PGPR) originated from these legumes is of great value for their application in enhancing plant stress resistance and facilitating ecological restoration in arid areas. However, systematic research on the functional diversity of the PGPR of leguminous plants in arid zones remains insufficient. This review focuses on the PGPR of the leguminous plants in arid regions of China, clarifies their geographical distribution and ecological advantages in arid environments, and elucidates the stress resistance and growth promoting mechanisms of the PGPR, along with their application prospects in enhancing plant stress tolerance. Furthermore, we suggest that future research should focus on in-depth exploration of microbial resources, clarifying the adaptability of legumes to different soil types in arid regions, and promoting the application of PGPR for legumes in arid areas. This study provides valuable clues and guidance for the precise construction and application of synthetic microbial communities to enhance plant stress resistance and ensure ecological and agricultural sustainability in arid regions.
