印度梨形孢(Piriformospora indica)增强植物抗逆境胁迫能力的研究进展

Research progress of Piriformospora indica in enhancing stress resistance of plant

印度梨形孢是一种可在多种植物根部定殖的内生真菌,能与多种植物形成共生体,提高植物对外界营养的吸收能力,促进次生代谢产物的积累,提高植物对生物及非生物胁迫的抵抗能力,同时可增加植物的生物产量,对宿主植物产生许多有益影响。因此,印度梨形孢作为优良的生物防治和土壤改良因子,在农业生产方面显示出巨大的应用前景。本文结合本课题组近年研究结果及近10年间相关科学工作者的研究,系统总结了印度梨形孢在增强植物抗生物胁迫与非生物胁迫方面的研究进展,旨在为更好地发挥其潜在价值提供参考。

Piriformospora indica, an endophytic fungus, colonizes the roots of various plant species to promote their growth, nutrient absorption, accumulation of secondary metabolites, and tolerance to biotic and abiotic stresses and increase their biomass. Therefore, P. indica has great potential for biocontrol and soil improvement and thus can be applied in agricultural production. In this paper, we summarized the research progress of P. indica in improving the resistance of plants to biotic and abiotic stresses in recent 10 years, hoping to enhance the understanding P. indica-plant interaction and bring into full play its functions.
