Arbuscular mycorrhizal fungi (AMF),are widely distributed in the soil and plant roots of almost all agricultural ecosystems.In this symbiosis,AMF consumes carbohydrates produced by the host plant using the hyphae associated with the roots for growth and reproduction;at the same time arbuscular mycorrhizal hyphae enhance the capacity for root absorption,which provides nutrients needed for growth (such as phosphorus and nitrogen).Legumes can form symbiosis with arbuscular mycorrhizal fungi.Numerous studies indicate that ar-buscular mycorrhizal fungi can improve legume growth,promote the absorption of mineral nutrients and wa-ter,and enhance biological nitrogen fixation capacity and stress resistance.The aim of this study was to enable better use of mycorrhizal fungi to promote legume production;the signal transduction mechanisms that may exist during the establishment of symbiosis were analyzed and the responses of legume yield and nutritional val-ue to arbuscular mycorrhizal are discussed.The internal mechanisms of increased stress resistance due to ar-buscular mycorrhizal are clarified,potential mechanisms of the interactions between arbuscular mycorrhizal and rhizobia are explored and the prospects for arbuscular mycorrhizal and legumes symbiosis studies in the future are addressed.

基于全球气候变化和能源危机的趋势,寻找新的替代能源已经成为应对气候变化的一种创新策略.柳枝稷(Panicum virgatum L.)是原产于北美的一种多年生C4能源植物,能够增加土壤碳固存,并且可用于提取和生产纤维素乙醇减少能源消耗.上世纪90年代初,柳枝稷在我国西北地区种植成功并表现出了良好的生态适应性.丛枝菌根真菌(Arbuscular Mycorrhizal Fungi,AMF)是一类广泛分布在土壤中与植物根系共生的真菌.这类微生物不但能够促进植物生长、提高其抗逆性,还能在植物—土壤系统碳转移和陆地生态系统碳氮循环过程中发挥重要作用.本文重点围绕丛枝菌根真菌的固碳机理、柳枝稷的作用与固碳机理、丛枝菌根真菌与柳枝稷的协同固碳机理及丛枝菌根真菌参与土壤碳氮循环等方面的内容做了详尽的综述,并为进一步开展有关丛枝菌根真菌与柳枝稷协同固碳机制的研究提出了建议.
