16S rDNA Sequence Analysis of Representative Strains of Two Rhizobial New Groups Isolated from Astragalus spp.
两个黄芪根瘤菌新类群代表菌株的16S rDNA序列分析

The full-length 16S rDNA sequences of representative strain CA8561 and JL84 of two Rhizobial new groups isolated from Astragalus spp. were sequenced. An unrooted tree was produced to determine their phylogenetic relationship. The result showed that CA8561 fell into Rhizobium branch and JL84 fell into Sinorhizobium branch.
