摘要:
植物内生真菌可以通过多样化途径来增强植物体的营养生理和抗性机能，本文从内生真菌的定义、分类及内生真菌与植物防御调控的关系进行阐述，重点分析内生真菌诱导植物体内防御酶系，促进植物次生代谢产物合成及增强植物抗逆性的重要功能与特性，同时对内生真菌诱导植物体内激素合成、防御基因表达及防御信号传导途径的作用机理进行探讨，进一步明确了内生真菌与植物防御互作关系，并提出了未来内生真菌在农业生产中应用前景及科研任务，以期为深入揭示植物抗逆机制及改良植物品种抗性提供重要的参考依据。Plants endogenous fungi can be through diversified path to enhance plant nutrition physiological and defence functions. definition, classification of endogenous fungi and regulation relationship of endoge- nous fungi and plant defense control expounded in this paper, focus analysis for endogenous fungi important functional and characteristics of the induced defense enzymes, promote plant secondary metabolic product synthetic and enhance resist adversity, at the same time, those endogenous fungi induced plant intimate hor- mone synthesize, defense gene expression and mechanisms of signal transmission channels of defense were explore. This has clearly defined reciprocity relations of endogenous fungi and plant defense. And application prospects of endogenous fungi in agricultural production and scientific research mission in the future were advance, in order to further reveal pant defence mechanisms and improve the plants resistant to provide im- portant reference information.
