Abstract:Ectomycorrhizal occupies an important position in the forest symbiosis system, and plays a role in improving the resistance of plants. In the field of mycorrhizology, the research on the interaction between ectomycorrhizal and abiotic stress is far less than other types of mycorrhizal. In particular, it lacks comprehensive summary comments. This article summarizes the research in the past 5 years, and elaborates the relationship between mycorrhizal symbiotes and plant resistance under abiotic stress (drought, cold, high temperature, saline-alkali, heavy metals and toxic substances); it elaborates that other factors and ectotrophic mycorrhiza have a kind of ability that they can cooperate to improve the plant resistance to abiotic stress; it elaborates how exogenous mycorrhiza alleviates abiotic stress by physiological and genetic means. This paper combines three aspects of research on contaminated soil remediation, functional protein expression, and microbial ecosystems. This paper analyzes current research hotspots and existing deficiencies, and looks forward to future research directions to provide useful ideas for forest ecological restoration and mycorrhizal research.
