摘　　要：为研究和利用华东地区豆科植物根瘤菌的种质资源多样性,对从华东地区豆科木本植物根瘤分离获得的23个菌株进行了16S rDNA全序列分析,并与相关参比菌株的16S rDNA序列进行了比较及聚类分析,建立了23株华东地区豆科木本植物根瘤菌的发育树状图,这一分析结果与来自形态学的鉴别结果吻合,初步确定了23株豆科木本植物根瘤菌分类地位。To study and make full use of Rhizobium diversity in east-area of China, the full length 16S rDNA sequences of 23 Rhizobium strains isolated from leguminosae woody plants in east China area were Lested. At the same time, those of selected strains downloaded from GenBank were compared. The phylogenetic tree was therefore constructed. The analysis result was consistent with those from morphology. The taxonomic position of 23 Rhizobium strains was determined.
