作者主要就这一早期结瘤过程中结瘤因子的结构和功能作一综述。
The phylogenetic studies on nod genes have promulgated that the host range of rhizobia appeared to have a higher interrelationship to the common nod genes than other genes.
结瘤基因的系统发育揭示出根瘤菌宿主范围与共同性结瘤基因间比其它基荫的相关性更高。
Rhizobia establish a symbiotic relationship with their host plant ― exchanging nitrogen for nutrients ― by forming nodules, which penetrate the roots and sometimes stems of the plant.
根瘤菌通过形成根瘤和它们的宿主建立了一种共生关系——用氮换取营养。 根瘤通常会渗透进植物的根，有时候还会渗透进植物的茎。
