摘要
本综述着重讨论根瘤菌及其豆科植物宿主在共生固氮作用中的几个重要问题。根瘤菌和豆科植物在根瘤发育过程中的相互作用。根瘤菌在根瘤的植物细胞中分化成类菌体,使空气中的 N_2还原成 NH_4^+用作宿主植物的营养来源。文中还介绍了几种适用于根瘤菌基因操作以进行共生固氮研究的分子遗传学技术。
This review was focused on some aspect of nitrogen fixation by rhi- zobia in symbiosis with their legume host.The interaction of Rhizobium and legume plant results in the development of nodules.Inside these nodules the rhizobia inhabit plant cells and differentiate into"bacteriods",which re- duce dinitrogen to ammonia,that is used by the legume host as a nutrient source.The molecular genetic techniques of Rhizobium genetics pertaining to studies described in this paper.
