综述了内生真菌通过产生植物生长物质、活化养分等促进寄主生长，并通过降低活性氧危害，帮助寄主获得诱导系统抗性，分泌有毒物质遏制草食动物取食等提高寄主植物抗逆性的机理。内生真菌还可能演化为其他植物的病原菌，通过抑制别的植物生长而为寄主获得更多有效环境资源，提出外来植物入侵性的获得可能与内生菌的促进作用有关。

Plant endophytes are microorganisms that live within the healthy host plant tissues without cau-sing any visible symptoms.Plant endophytes improve growth of host plant by producing growth substance and increase mineral nutrient use efficiency.They enhanced stress tolerance of host plant by reducing the harm of ac-tive oxygen,helping to gain induced systemic resistance,secreting toxic substances to herbivores.Plant endo-phytes are likely to develop into pathogen and suppress the growth of other species and then gain more environ-mental resources for their host plants.The invesiveness of introduced plants may benefit from above characteris-tics of plant endophytes.This paper reviewed elaborated action mechanism of that endophytes improve growth and enhance adversity resistance of host plants,speculated that plant endophytes may contribute to alien plant invasion.
