摘要 丛枝菌根(AM)真菌与80%以上的陆地植物形成共生关系,可以与土壤中寄主植物根或者离体根器官组织共生.AM真菌的根外菌丝(ERM)可以吸收各种形态的氮源,然后传递给寄主植物根部.然而,关于AM真菌吸收、同化各种氮源,并且传递给寄主植物的机制尚未清楚,这导致了缺乏描述AM真菌菌丝内氮移动的总体模型.最近用15N标记实验、关键酶活性检测和基因表达等研究了AM真菌与RiT-DNA转基因胡萝卜根共生系统中N同化、运转和传递的总体途径.本文根据最近大量的实验进展综述了AM真菌吸收、同化、运转和传递给寄主植物的N形态及其机制.并且讨论了萌发孢子对氮和碳源利用的形态,以及他们对氨基酸代谢的影响.最后绘出了AM真菌N代谢的总体途径模型.
