Common soybean inoculant strains in Brazil are members of Bradyrhizobium elkanii.

چکیده
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.

Genetic diversity of symbiotic Bradyrhizobium elkanii populations recovered from inoculated and non-inoculated Acacia mangium field trials in Brazil.
Acacia mangium is a legume tree native to Australasia. Since the eighties, it has been introduced into many tropical countries, especially in a context of industrial plantations. Many field trials have been set up to test the effects of controlled inoculation with selected symbiotic bacteria versus natural colonization with indigenous strains. In the introduction areas, A. mangium trees spontan...
متن کاملDraft Genome Sequences of Bradyrhizobium elkanii Strains BLY3-8 and BLY6-1, Which Are Incompatible with Rj3 Genotype Soybean Cultivars
We report here the draft genome sequences of Bradyrhizobium elkanii strains BLY3-8 and BLY6-1, which are incompatible with Rj3 genotype soybean cultivars. The genome sequences of these strains will be useful to identify a causal gene for this incompatibility.
متن کاملIdentification of Bradyrhizobium elkanii Genes Involved in Incompatibility with Vigna radiata
The establishment of a root nodule symbiosis between a leguminous plant and a rhizobium requires complex molecular interactions between the two partners. Compatible interactions lead to the formation of nitrogen-fixing nodules, however, some legumes exhibit incompatibility with specific rhizobial strains and restrict nodulation by the strains. Bradyrhizobium elkanii USDA61 is incompatible with ...
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 کاملApplication of representational difference analysis to identify genomic differences between Bradyrhizobium elkanii and B. Japonicum species
Bradyrhizobium elkanii is successfully used in the formulation of commercial inoculants and, together with B. japonicum, it fully supplies the plant nitrogen demands. Despite the similarity between B. japonicum and B. elkanii species, several works demonstrated genetic and physiological differences between them. In this work Representational Difference Analysis (RDA) was used for genomic compar...
