Research advances in functional processes and factors of rhizosphere microorganisms in regulating forest growth
Rhizosphere is the interface between roots and soils in forests,within which the micro-ecosystem is formed by the interaction of root metabolites,organisms and edaphic physicochemical factors.Due to root activities,rhizosphere has specific microbial community and function,with complex effects on forest growth and development and soil ecological processes.Development of high-throughput sequencing technology has advanced our understan-ding on the mechanism of rhizosphere microorganisms in plant growth promotion and stress resistance beyond the limitation of culture difficulties.Microbial community,function and interactions with forests were progressed well,but there are still gaps in the mechanism of rhizosphere microbial assembly regulated by plant metabolism and the development of synthetic microbial communities.We first summarized the functions of rhizosphere microorganisms in plant growth and stress resistance of forests,and addressed the application of synthetic microbial communities.Then,we discussed the effects of biotic and abiotic factors on rhizosphere microorganisms.Finally,we put forward the research on omics and community of forest rhizosphere microorganisms under the background of global climate changes,aiming to provide a theoretical support for the application of microbial resources in forest health mainte-nance and sustainable development of forestry.
