摘 要:
丛枝菌根(arbuscular mycorrhizal, AM)真菌是土壤中重要的生物成员之一, 对植物具有多种有益效应。AM真菌的基 本功能之一是增强植物的抗逆性, 在全球气候变化的今天尤其重要。本文总结了AM真菌降低温度胁迫、水分胁迫、盐胁 迫、重金属胁迫、病虫害、以及杂草对植物造成的危害和提高植物抗逆性的效应; 阐述了AM真菌提高植物抗逆性的作用 机制; 并讨论了当前该领域研究存在的难题及今后的展望。旨在为探讨提高植物抗逆性策略与途径提供参考。关键词:丛枝菌根真菌; 逆境; 抗逆性

Abstract:
Arbuscular mycorrhizal (AM) fungi are an important inhabitant member in rhizosphere soil, having many beneficial effects on plants. Increased plant stress resistance is one of essential functions of AM fungi which is especially important under modern global climate changes. Effects of AM fungi on reducing the damages caused by lower temperature, water, salt, heavy metal stresses, disease, pests and weed threatening, and on increased stress resistance are summarized in this paper. The mechanisms of increased stress resistance of plants by AM fungi are documented, and problems in present researches, research trends and prospects in the future investigation are also discussed in order to provide idea and foundation in probing strategies and pathways of improved stress resistance of plants.Key words: AM fungi; stressed environments; stress resistance
