摘　　要：菌根是自然界普遍存在的一种植物共生体,菌根真菌与植物的互惠共生关系可促进土壤中矿质养分的活化与释放,提高土壤养分生物有效性,从而改善植物营养状况。本文分别从菌丝结构、生理生化、分子生物学等几个方面对菌根真菌如何摄取氮、磷元素,氮、磷代谢转运的分子机理,以及菌根真菌对植物吸收氮、磷的影响等方面的研究进展进行综述,并探讨了目前存在的主要问题与未来的研究重点。Mycorrhizal fungi are a kind of plant symbiont ubiquitous in nature.The mutual-symbiotic relationship between mycorrhizal fungi and plants can promote the activation and release of mineral nutrients in soil,improve the biological availability of soil nutrients,and thus improve the nutritional status of plants.In this paper,the research progress of how mycorrhizal fungi take up nitrogen and phosphorus,the molecular mechanism of nitrogen and phosphorus metabolism and transport,and the influence of mycorrhizal fungi on plant uptake of nitrogen and phosphorus fro m the aspects of mycelial structure,physiology,biochemistry and molecular biology were introduced.And the main proble ms and future research priorities were also analyzed.
