Abstract: The review discussed the symbiosis microorganisms on environmental adaptability for plants on three terms, including the factors affecting endophytic communities, the ways that microbes interact with each other, and the exogenous strains affecting the endophytic diversity. We introduced how the symbiosis with microorganisms was important for plant surviving on extremely environment, and what were the factors that affecting on the group structure of endophytes. The plants can recruit the required microbial by regulating the rhizosphere microbial communities through root exudates. And some unique groups of endophytes were established based on species and developmental stages. The successes of symbiotic of plant and microbe were the balance based on the competition and coordination among taxa, or their metabolite interactions. The inoculation of growth-promoting strains artificially or pathogen infection could also changes the structure of the groups. The emphasis is to provide reference for improving plant adaptability to adversity by using friendly microbial strains.
