摘　　要：对黄芪根瘤菌两个新类群中心菌株CA85 6 1和JL84进行了 1 6SrDNA全序列测定 ,并进行了系统发育学分析。结果表明 ,CA85 6 1位于Rhizobium分支中 。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.
