bradyrhizobium pachyrhizi sp. nov. and bradyrhizobium jicamae sp. nov., isolated from effective nodules of pachyrhizus erosus.	several strains isolated from the legume pachyrhizus erosus were characterized on the basis of diverse genetic, phenotypic and symbiotic approaches. these novel strains formed two groups closely related to bradyrhizobium elkanii according to their 16s rrna gene sequences. strains pac48t and pac68t, designated as the type strains of these two groups, presented 99.8 and 99.1% similarity, respectively, in their 16s rrna gene sequences with respect to b. elkanii usda 76t. in spite of these high simi ...	2009	19567584
bradyrhizobium lablabi sp. nov., isolated from effective nodules of lablab purpureus and arachis hypogaea grown in southern china.	five strains isolated from root nodules of lablab purpureus and arachis hypogaea grown in anhui and sichuan provinces of china were classified within the genus bradyrhizobium. these strains had identical 16s rrna nucleotide sequences which shared 99.22% and 99.48% similarities with the most related strains of bradyrhizobium jicamae pac 68(t), bradyrhizobium pachyrhizi pac 48(t) and bradyrhizobium elkanii usda 76(t). polyphasic approaches including 16s rrna gene rflp, igs-rflp, box-pcr, comparati ...	2010	21112989
rhizobia indigenous to the okavango region in sub-saharan africa: diversity, adaptations, and host specificity.	the rhizobial community indigenous to the okavango region has not yet been characterized. the isolation of indigenous rhizobia can provide a basis for the formulation of a rhizobial inoculant. moreover, their identification and characterization contribute to the general understanding of species distribution and ecology. isolates were obtained from nodules of local varieties of the pulses cowpea, bambara groundnut, peanut, hyacinth bean, and common bean. ninety-one of them were identified by box ...	2014	25239908
bradyrhizobium neotropicale sp. nov., isolated from effective nodules of centrolobium paraense.	root nodule bacteria were isolated from centrolobium paraense tul. grown in soils from the amazon region, state of roraima (brazil). 16s rrna gene sequence analysis of seven strains (br 10247(t), br 10296, br 10297, br 10298, br 10299, br 10300 and br 10301) placed them in the genus bradyrhizobium with the closest neighbours being the type strains of bradyrhizobium paxllaeri (98.8 % similarity), bradyrhizobium icense (98.8 %), bradyrhizobium lablabi (98.7 %), bradyrhizobium jicamae (98.6 %), bra ...	2014	25205796
genetic diversity and evolution of bradyrhizobium populations nodulating erythrophleum fordii, an evergreen tree indigenous to the southern subtropical region of china.	the nodulation of erythrophleum fordii has been recorded recently, but its microsymbionts have never been studied. to investigate the diversity and biogeography of rhizobia associated with this leguminous evergreen tree, root nodules were collected from the southern subtropical region of china. a total of 166 bacterial isolates were obtained from the nodules and characterized. in a pcr-based restriction fragment length polymorphism (rflp) analysis of ribosomal intergenic sequences, the isolates ...	2014	25085491
genome sequence of bradyrhizobium pachyrhizi strain pac48t, a nitrogen-fixing symbiont of pachyrhizus erosus (l.) urb.	bradyrhizobium pachyrhizi pac48(t) has been isolated from a jicama nodule in costa rica. the draft genome indicates high similarity with that of bradyrhizobium elkanii. several coding sequences (cdss) of the stress response might help in survival in the tropics. pac48(t) carries nodd1 and nodk, similar to bradyrhizobium (parasponia) anu 289 and a particular nodd2 gene.	2015	26383651

phylogenetic multilocus sequence analysis of indigenous slow-growing rhizobia nodulating cowpea (vigna unguiculata l.) in greece.	cowpea (vigna unguiculata) is a promiscuous grain legume, capable of establishing efficient symbiosis with diverse symbiotic bacteria, mainly slow-growing rhizobial species belonging to the genus bradyrhizobium. although much research has been done on cowpea-nodulating bacteria in various countries around the world, little is known about the genetic and symbiotic diversity of indigenous cowpea rhizobia in european soils. in the present study, the genetic and symbiotic diversity of indigenous rhi ...	2017	28214058
draft genome sequence of bradyrhizobium sp. strain br 3262, an effective microsymbiont recommended for cowpea inoculation in brazil.	the strain br 3262 was isolated from nodule of cowpea (vigna unguiculata l. walp) growing in soil of the atlantic forest area in brazil and it is reported as an efficient nitrogen fixing bacterium associated to cowpea. firstly, this strain was assigned as bradyrhizobium elkanii, however, recently a more detailed genetic and molecular characterization has indicated it could be a bradyrhizobium pachyrhizi species. we report here the draft genome sequence of b. pachyrhizi strain br 3262, an elite b ...	2017	27216893
