Identification of rhizobial strains nodulating Egyptian grain legumes.
Fifty four bacterial strains were isolated from root nodules of the grain legumes Cicer arietinum, Lens esculentus, Phaseolus vulgaris, Pisum sativum, and Vicia faba grown in cultivated lands of Beni-Suef Governorate (Egypt). Repetitive extragenic palindromic (REP)-polymerase chain reaction (PCR) clustered the strains into 15 REP-PCR groups. The nearly complete sequence of the 16S rRNA gene fro...
متن کاملSymbiotic Efficiency of Native Rhizobia Nodulating Common Bean (Phaseolus vulgaris L.) in Soils of Western Kenya
This study was conducted to determine the abundance and symbiotic efficiency of native rhizobia nodulating common bean in Kisumu and Kakamega, Kenya. Soil sampling was carried out in three farms that had been used for growing common bean for at least two seasons and one fallow land with no known history of growing common bean or inoculation. Abundance of soil rhizobia and symbiotic efficiency (...
متن کاملColonization of Phaseolus vulgaris nodules by Agrobacterium-like strains.
Non-nodulating Agrobacterium-like strains identified among root nodule isolates of common bean were labeled with gusA, a reporter gene encoding beta-glucuronidase (GUS). Bean plants were then co-inoculated with an infective Rhizobium strain and labeled transconjugants of Agrobacterium-like strains. Blue staining of nodules showed that Agrobacterium-like strains were able to colonize these symbi...
متن کاملRhizobium tropici, a novel species nodulating Phaseolus vulgaris L. beans and Leucaena sp. trees.
A new Rhizobium species that nodulates Phaseolus vulgaris L. and Leucaena spp. is proposed on the basis of the results of multilocus enzyme electrophoresis, DNA-DNA hybridization, an analysis of ribosomal DNA organization, a sequence analysis of 16S rDNA, and an analysis of phenotypic characteristics. This taxon, Rhizobium tropici sp. nov., was previously named Rhizobium leguminosarum biovar ph...
متن کاملGlycosidases of Phaseolus vulgaris
The enzymes, cr-galactosidase, P-galactosidase, a-mannosidase, P-glucosidase, and p-acetylglucosaminidase, have been purified from the germinating seeds of Phaseolus vulgaris. All five enzymes have been simultaneously isolated in a highly active form. The pH optimum, K,,,, and energy of activation of each glycosidase for the reaction of hydrolysis of the appropriate P-nitrophenyl glycoside have...
