摘　　要：植物与真菌的共生关联表现出有利于植物对矿物质和水分等营养物质的吸收并减少非生物和生物胁迫,而植物为丛枝菌根真菌(AMF)提供碳源等物质。据报道,从被子植物到裸子植物大约有90%具有菌根真菌。在生命周期中,丛枝菌根真菌必须具有植物根系作为宿主,并且这种共生关系是相互良性的,其中AM为植物吸收养分提供了帮助,而植物为真菌提供了碳源。AM真菌已被小规模用作生物防治剂,以代替农药抵抗各种土壤传播的植物病原体的威胁作用。该文主要介绍了AM真菌对植物致病真菌、细菌的生物防治作用,及其与植物致病病毒间的相互作用。The symbiotic association of plants with fungus exhibited arbuscular mycorrhizal(AM)association that favour mineral and water nutrition and decrease abiotic and biotic stresses.It has been reported that approximately 90%of plants are colonized by the mycorrhizal fungi species ranging from angiosperms to gymnospermic plants,while several of them are devoid of AM fungi.During its life cycle,the arbuscular mycorrhizal fungi must have a host and this symbiotic association is reciprocally benign,where the AM provides help to the plant in nutrients uptake,and in return,the plant provides the fungus with carbon.The AM fungi have been used as a biocontrol agent in lieu of their antagonistic interaction with various soilborne plant pathogens.This paper mainly introduced the biological control effect of AM fungi on plant pathogenic fungi and bacteria,and the interaction between AM fungi and plant pathogenic viruses.
