| bradyrhizobium vignae sp. nov., a nitrogen-fixing symbiont isolated from effective nodules of vigna and arachis. | twenty one strains of symbiotic bacteria from root nodules of local races of cowpea (vigna unguiculata), bambara groundnut (vigna subterranea) and peanuts (arachis hypogaea) grown on subsistence farmers' fields in the kavango region of namibia, were previously characterized as a novel group within the genus bradyrhizobium. to verify their taxonomic position, the strains were further analysed using a polyphasic approach. 16s rrna gene sequences were most similar to bradyrhizobium manausense br 33 ... | 2016 | 26463703 |
