Polyphasic characterization of rhizobia that nodulate Phaseolus vulgaris in West Africa (Senegal and Gambia).
Fifty-eight new isolates were obtained from root nodules of common bean (Phaseolus vulgaris) cultivated in soils originating from different agroecological areas in Senegal and Gambia (West Africa). A polyphasic approach including both phenotypic and genotypic techniques was used to study the diversity of the 58 Rhizobium isolates and to determine their taxonomic relationships with reference str...
متن کاملGenetic diversity and phylogeny of rhizobia that nodulate acacia spp. in morocco assessed by analysis of rRNA genes
Forty rhizobia nodulating four Acacia species (A. gummifera, A. raddiana, A. cyanophylla, and A. horrida) were isolated from different sites in Morocco. These rhizobia were compared by analyzing both the 16S rRNA gene (rDNA) and the 16S-23S rRNA spacer by PCR with restriction fragment length polymorphism (RFLP) analysis. Analysis of the length of 16S-23S spacer showed a considerable diversity w...
متن کاملComparison of rhizobia that nodulate Medicago laciniata and Medicago truncatula present in a single Tunisian arid soil.
The rhizobia present in a single arid region Tunisian soil that nodulate Medicago laciniata and Medicago truncatula were compared. All isolates, 40 from each host, were Sinorhizobium meliloti based on 16S rRNA polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) patterns and subsequent confirmation by sequence analysis of the 16S rRNA genes in four representatives from ...
متن کاملCharacterization of strains unlike Mesorhizobium loti that nodulate lotus spp. in saline soils of Granada, Spain.
Lotus species are forage legumes with potential as pastures in low-fertility and environmentally constrained soils, owing to their high persistence and yield under those conditions. The aim of this work was the characterization of phenetic and genetic diversity of salt-tolerant bacteria able to establish efficient symbiosis with Lotus spp. A total of 180 isolates able to nodulate Lotus cornicul...
متن کاملPlasmid-linked nif and "nod" genes in fast-growing rhizobia that nodulate Glycine max, Psophocarpus tetragonolobus, and Vigna unguiculata.
Forty-nine fast-growing Rhizobium strains from the nodules of 26 different tropical legume genera were screened to find isolates that would (i) nodulate, e.g., winged beans, so producing large nodules for RNA and protein isolation; (ii) also nodulate various small-seeded legumes, thus allowing screening of large numbers of mutants; and (iii) harbor plasmids containing nif structural genes as we...
