Genetic diversity of peanut rhizobia isolated from Jianghan Plain and the adjacent area
江汉平原及其周边地区花生根瘤菌的遗传多样性

Genetic diversity of rhizobia from peanut on Jiangh an Plain and adjacent area was studied by the methods of Randomly Amplified Poly morphic DNA (RAPD) and 16S-23S rRNA Intergenic Spacer (IGS) PCR RFLP. The resul ts showed that all strains were divided into 2 groups at the similarity 48% or 5 0% respectively. Peanut rhizobia and representatives of B.japonicum and B. elkanii were clustered into group I and the reference strains of Rhizobium, Sinorhizobium, Mesorhizobium and Agrobacterium were clustered into...
