1 Hudeiba Research Station (ARC), P. O. Box 31, Eddamer, Sudan 2 National Centre for Research, Environment and Natural Resources Research Institute (ENRRI) P. O. Box 6096 Khartoum, Sudan *Corresponding Author’s E-mail: [email protected] The performance of two chickpea in response to three Rhizobium strains was evaluated. The main objective of the work was to study the effect of inoculation ...

High soil temperatures in tropical areas limit nodulation and dinitrogen fixation by strains of Rhizobium. Several heat-tolerant bean-nodulating Rhizobium strains have been isolated previously. However, the basis of their resistance to heat remains unknown. In this study, we compared the effects of heat on symbiotic nitrogen fixation, cell survival, amino acid uptake, and protein synthesis in a...

Three strains of aerobic chemoorganotrophic naphthalene-degrading bacteria (designated TSY03b(T), TSY04, and TSW01) isolated from sediment of a polychlorinated-dioxin-transforming microcosm were characterized. These strains had Gram-negative-stained, rod-shaped cells measuring 0.6‒0.9 μm in width and 1.2‒3.0 μm in length and were motile by means of peritrichous flagella. Naphthalene was utilize...

A quantitative method was developed to measure the binding of fluorescent-labeled lentil (Lens esculenta Moench), pea (Pisum sativum L.), broad bean (Vicia faba L.), and jackbean (Canavalia ensiformis L., DC.) lectins to various Rhizobium strains. Lentil lectin bound to three of the five Rhizobium leguminosarum strains tested. The number of lentil lectin molecules bound per R. leguminosarum 128...

Strains of Rhizobium etli, Rhizobium meliloti, and Rhizobium tropici decreased their capacity to grow after successive subcultures in minimal medium, with a pattern characteristic for each species. During the growth of R. etli CE 3 in minimal medium (MM), a fermentation-like response was apparent: the O2 content was reduced and, simultaneously, organic acids and amino acids were excreted and po...

Isolated plasmid DNA from Rhizobium leguminosarum was hybridised with cellular RNA from broth-cultured bacteria and endosymbiotic bacteroids. From these hybridisation, experiments it is concluded that plasmid genes are strongly expressed in bacteroids and only weakly or not at all in bacteria. From the hybridisation of plasmid DNA with the cloned structural nif genes of Klebsiella pneumoniae it...

Procedures based on DNA hybridization and PCR were developed for quality control of Rhizobium inoculants. Inoculants for pea and goat's rue were produced by Elomestari Ltd., Juva, Finland, in sterile dry fine peat by the standard procedure used by the company. The inoculants contained Rhizobium galegae HAMBI 1174 and HAMBI 1207 and an R. leguminosarum biovar vicia strain, 16HSA, either solely o...

We developed a rapid, inexpensive method for isolating and identifying Rhizobium leguminosarum by. phaseoli strains from bean root nodules. The method can be used for other small or medium-sized nodules such as those of clover, alfalfa and peas. With this method, one person can process 115 nodules/h. Using a simple apparatus made of plexiglass and machine bolts, we simultaneously crushed 24 sur...

Rhizobium etli is a Gram-negative soil-dwelling alphaproteobacterium that carries out symbiotic biological nitrogen fixation in close association with legume hosts. R. etli strains exhibit high sequence divergence and are geographically structured, with a potentially dramatic influence on the outcome of symbiosis. Here, we present the genome sequence of R. etli CNPAF512, a Brazilian isolate fro...
