However, there's a lot of acid soil in South of China, and acid-tolerant rhizobia are in short.

然而，我国南方酸性土壤分布广、面积大，耐酸苜蓿根瘤菌资源缺乏。

This article means to give a brief review on the structure and function of the nod factors in the early steps of the interaction between Rhizobia and Legumes.

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。
