外生菌根对植物非生物胁迫的缓解作用及作用机理研究进展

外生菌根在林木共生系统中占据重要的地位,具有提高宿主植物抗逆性的作用.在菌根学领域中,外生菌根与非生物胁迫互作的研究要远少于其他类型的菌根,尤其是缺乏综合、全面的总结性评述.文中总结了近5年来的相关研究,阐述了非生物胁迫(干旱、寒冷、高温、盐碱、重金属和有毒物质)下菌根共生体与植物抗逆性的关系,其他因子与外生菌根协同提...

Mitigation effect and regulation mechanism of ectomycorrhizal on plant under abiotic stress: a review

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.
