DNA-DNA hybridization study of Bradyrhizobium strains.
DNA-DNA hybridizations were performed between Bradyrhizobium strains, isolated mainly from Faidherbia albida and Aeschynomene species, as well as Bradyrhizobium reference strains. Results indicated that the genus Bradyrhizobium consists of at least 11 genospecies, I to XI. The genospecies formed four subgeneric groups that were more closely related to each other (>40% DNA hybridization) than to...
متن کاملSCREENING SOYBEAN GENOTYPES FOR PROMISCUOUS SYMBIOTIC ASSOCIATION WITH Bradyrhizobium STRAINS
The current low soybean (Glycine max L. Merrill) yields in Sub-Saharan Africa can be alleviated by developing promiscuous genotypes. The research trend in Africa is towards developing promiscuous varieties for less labour and high yields in soybean production. A greenhouse experiment was conducted at Makerere University Agricultural Research Institute, Kabanyolo (MUARIK) with the aim of screeni...
متن کاملDiversification of lupine Bradyrhizobium strains: evidence from nodulation gene trees.
Bradyrhizobium strains isolated in Europe from Genisteae and serradella legumes form a distinct lineage, designated clade II, on nodulation gene trees. Clade II bradyrhizobia appear to prevail also in the soils of Western Australia and South Africa following probably accidental introduction with seeds of their lupine and serradella hosts. Given this potential for dispersal, we investigated Brad...
متن کاملA Selective Medium for the Isolation and Quantification of Bradyrhizobium japonicum and Bradyrhizobium elkanii Strains from Soils and Inoculants.
The ecological examination of members of the family Rhizobiaceae has been hampered by the lack of a selective medium for isolation of root nodule bacteria from soil. A novel non-antibiotic-containing medium has been developed which allows selective isolation of Bradyrhizobium japonicum and B. elkanii strains from soil and inoculants. The medium, BJSM, is based on the resistance of B.japonicum a...
متن کاملCommon soybean inoculant strains in Brazil are members of Bradyrhizobium elkanii.
The Brazilian inoculant strains 29W and 587 were found to be members of Bradyrhizobium elkanii primarily on the basis of 16S rRNA gene sequences identical to that of B. elkanii USDA76 and on the basis of reactivity with antibodies against serogroups 76 and 31, respectively. The agronomic consequences of using strains of B. elkanii as soybean inoculants are discussed.
