Abstract:

Abstract: Recently，some research reports showed varied endophytic bacteria in the root nodules of some legumes，which attracts great interest in research field of rhizobia． Here，we reviewed the discovery，identification of some endophytic bacteria ( Agrobacterium，non-symbiotic rhizobia，and other bacteria) in root nodules and their influence on symbiosis or plant growth，to understand the microecosystem of root nodule and to extend the field of rhizobia research．
