丛枝菌根真菌的生理生态功能研究进展

rbuscular mycorrhizal (AM) fungi can form mutualistic associations with the roots of most terrestrial plants. Plants supply AM fungi with carbohydrates, and in return, fungi increase phosphorus and nitrogen caputure of their hosts. It has been well accepted that AM fungi play key roles in enhancing the nutrient caputure and stress tolerance of their hosts, influencing the communities of plant and soil microbes, and in regulating the biochemical cycles of most nutrient elements. In recent years, AM symbioses have fascinated many researchers from different reasearch fields, and the increasing works on the AM have greatly facilitated our understanding of the fungal eco-physiological propoerties as well as their key roles in maintaining ecosystem stability. In this review, the research progress of AM fungal eco-physiological functions has been well summaried, and we propose that the future researches on AM fungi should take the global change and anthropogenic activities into account.
