Two recent reports described the isolation of derivatives of a Rhizobium trifolii strain that had gained the ability to nodulate Glycine max and Vigna radiata and that had demonstrated altered patterns of carbon source utilization, free-living nitrogen fixation, and hydrogen uptake. More extensive characterization of these strains now supports the conclusion that these strains are R. japonicum and are not derived from the putative parent R. trifolii.
最近的两份报告描述了从三叶草根瘤菌菌株中分离出的衍生物,这些衍生物获得了对大豆和绿豆进行结瘤的能力,并且在碳源利用、自生固氮和氢气摄取方面表现出改变的模式。现在对这些菌株更广泛的特性分析支持了这样的结论,即这些菌株是日本根瘤菌,并非源自假定的亲本三叶草根瘤菌。
