Advances in Research on Phyllosphere Microorganisms and Their Interaction with Plants

There are abundant and diverse microbial communities in the phyllosphere of plants. Plants provide necessary living places and nutrients for the phyllosphere microorganisms, while the phyllosphere microorganisms affect the growth, development and metabolism of plants; both are in a process of dynamic balance. With the continuous exploration of the functions of phyllosphere microorganisms, more and more studies on the relationship between phyllosphere microorganisms and plants have been carried out. In order to better understand and apply the phyllosphere microorganisms, and combined with the relevant literature in recent years, this paper summarized the isolation and identification methods of the phyllosphere microorganisms, the sources and components of the phyllosphere microorganisms, and the interaction between the phyllosphere microorganisms and plants, which is helpful for a comprehensive understanding of the phyllosphere microorganisms. The research direction and emphasis of the phyllosphere microorganisms were discussed, providing a reference for future research.
