| rhizobium anhuiense as the predominant microsymbionts of lathyrus maritimus along the shandong peninsula seashore line. | beach pea [lathyrus maritimus bigelow, or lathyrus japonicus subsp. maritimus (l.) p.w. ball] is a wild legume distributed on the seashore line, and the rhizobia nodulating with this plant have been reported only rarely. in order to reveal the diversity of beach pea rhizobia on the seashore line of shandong peninsula, china, a total of 124 bacterial strains were isolated from the root nodules of beach pea plants collected from five sites. all the isolates were divided into five reca types after ... | 2016 | 27480059 |
| evidence of an american origin for symbiosis-related genes in rhizobium lusitanum. | randomly amplified polymorphic dna (rapd) analysis was used to investigate the diversity of 179 bean isolates recovered from six field sites in the arcos de valdevez region of northwestern portugal. the isolates were divided into 6 groups based on the fingerprint patterns that were obtained. representatives for each group were selected for sequence analysis of 4 chromosomal dna regions. five of the groups were placed within rhizobium lusitanum, and the other group was placed within r. tropici ty ... | 2011 | 21705533 |
| reclassification of rhizobium tropici type a strains as rhizobium leucaenae sp. nov. | rhizobium tropici is a well-studied legume symbiont characterized by high genetic stability of the symbiotic plasmid and tolerance to tropical environmental stresses such as high temperature and low soil ph. however, high phenetic and genetic variabilities among r. tropici strains have been largely reported, with two subgroups, designated type a and b, already defined within the species. a polyphasic study comprising multilocus sequence analysis, phenotypic and genotypic characterizations, inclu ... | 2011 | 21742822 |
| rhizobium vallis sp. nov., isolated from nodules of three leguminous species grown in yunnan province of china. | four bacterial strains isolated from root nodules of phaseolus vulgaris, mimosa pudica and indigofera spicata plants grown in yunnan province of china were identified as a lineage within the genus rhizobium according to the analysis of 16s rrna gene sequence, most similar with r. lusitanum p1-7(t) (99.1% sequence similarity) and r. rhizogenes iam13570(t) (99.0%). these strains also formed a distinctive group from the reference strains for defined rhizobium species in a polyphasic approach, inclu ... | 2010 | 21131504 |
| rhizobium multihospitium sp. nov., isolated from multiple legume species native of xinjiang, china. | thirty-one rhizobial strains isolated from nodules of legumes native of xinjiang, china, were characterized. these strains were classified as belonging to the genus rhizobium based on amplified 16s rdna restriction analysis (ardra). the strains were distinguished from recognized rhizobium species using analysis of 16s-23s rdna intergenic spacers (igs-rflp), sds-page analysis of whole proteins and box-pcr; the test strains always formed a distinct cluster with patterns that were quite different f ... | 2008 | 18599718 |
| rhizobium lusitanum sp. nov. a bacterium that nodulates phaseolus vulgaris. | the species phaseolus vulgaris is a promiscuous legume nodulated by several species of the family rhizobiaceae. during a study of rhizobia nodulating this legume in portugal, we isolated several strains that nodulate p. vulgaris effectively and also macroptilium atropurpureum and leucaena leucocephala, but they form ineffective nodules in medicago sativa. according to phylogenetic analysis of the 16s rrna gene sequence, the strains from this study belong to the genus rhizobium, with rhizobium rh ... | 2006 | 17082403 |
