Abstract:

Nitrogen-fixing symbiotic bacteria known as rhizobia can exist in different soils and adapt to different environmental conditions. The aim of this study was to determine the impact of pH on the growth of Rhizobium trifolii and Sinorhizobium meliloti. Rhizobial species were isolated using yeast extract mannitol agar medium) in which the pH values were adjusted to 5.0, 6.0, 8.0 and 9.0 by adding HCl and NaOH. The optimum pH for rhizobia is neutral or slightly alkaline (pH 8) and they are more sensitive to acidity. Sinorhizobium meliloti developed better in an acid medium compared to Rhizobium tr

ABSTRACT The stable, low-molecular-weight (LMW) RNA fractions of several rhizobial isolates of Phaseolus vulgaris grown in the soil of Lanzarote, an island of the Canary Islands, were identical to a less-common pattern found within Sinorhizobium meliloti (assigned to group II) obtained from nodules of alfalfa and alfalfa-related legumes grown in northern Spain. The P. vulgaris isolates and the group II LMW RNA S. meliloti isolates also were distinguishable in that both had two conserved inserts of 20 and 46 bp in the 16S-23S internal transcribed spacer region that were not present in other str

Abstract:

The growth of Rhizobium meliloti is sensitive to soil acidity, and its poor growth and survival limits the production from Medicago spp. on acid soils. In the selection of acid tolerant rhizobia for medics, growth in acidified laboratory media has been poorly related to persistence in acid soils. However, the Ca concentration in laboratory media may have been inadequate for growth of some rhizobial strains at low pH. Therefore, acid-tolerant and acid-sensitive strains of R. meliloti were grown in a buffered, defined medium at a range of Ca and P concentrations, and at several pH values. Growth

Abstract:

The bacterium Sinorhizobium meliloti Rm2011 forms N2-fixing root nodules on alfalfa and other leguminous plants. The pSymB chromid contains a 110-kb region (the ETR region) showing high synteny to a chromosomally located region in Sinorhizobium fredii NGR234 and related rhizobia. We recently introduced the ETR region from S. fredii NGR234 into the S. meliloti chromosome. Here, we report that, unexpectedly, the S. fredii NGR234 ETR region did not complement deletion of the S. meliloti ETR region in symbiosis with Medicago sativa. This phenotype was due to the bacA gene of NGR234 not being funct

Abstract:

The insertion sequence ISRm1 frequently occurs in Rhizobium meliloti and is a potential mutagen. Data for the frequency of ISRm1 transposition in the commercial inoculant strain SU47 (containing eight copies of IsRm1) indicate that this insertion sequence does not significantly affect the ability of SU47 to occupy nodules of alfalfa (Medicago sativa L.) grown at two field sites. Thirty representative isolates from the indigenous population of R. meliloti at each of these sites contained from 0 to 10 copies of IsRm1; there was no significant correlation between insertion sequence copy number an

Abstract:

Flavonoids are involved in a number of critical events in the interaction between nitrogen-fixing bacteria and legumes. To get a better understanding of the importance of flavonoids in the earliest stages of the alfalfa-Rhizobium meliloti symbiosis, we followed the expression of two chal-cone synthase (CHS) gene family members as well as of chalcone isomerase (CHI) and isoflavone reductase (IFR) genes. CHS transcripts increased 2 to 4 dpi (days post-inoculation) with wild-type rhizobia, but not after inoculation with the heterologous R. leguminosarum bv. trifolii or with an exopolysaccharide (

Abstract:

Legumes have the ability to form symbiotic interactions with soil bacteria, called rhizobia. Bacteria of the genus Rhizobium are able to convert atmospheric nitrogen into ammonia when compounds are exchanged between the bacteroid and its plant host. The present study describes the characterization of Rhizobium strains isolated from root nodules of Trifolium pratense and Medicago sativa grown in a greenhouse. The main objective of the experiment was to identify which medium is more suitable for the development of different strains of rhizobia. The Rhizobium strains are rod shaped, Gram negative

Legume growers and extension agents require advice on optimum conditions under which inoculants may be stored without deterioration of rhizobia or the effectiveness of the inoculant. This study was conducted to determine effects of storage duration and temperature on survival of Rhizobium meliloti in two inoculant carriers, one with a peat base and the other with a clay base. Inoculant subsamples were placed in polyethylene bags, then packaged into plastic containers and stored in wooden boxes at either −23 °C (freezer), 4 °C (refrigerator), or room temperature (21–33 °C).

Genetic mapping of pDS15 revealed that this cosmid clone carries the Sinorhizobium meliloti TCA cycle genes mdh, sucCDAB, sdhAB and part of lpdA. Three genes (mdh, sucC , and sucA) were completely sequenced and submitted to GenBank. The nucleotide and amino acid sequences of the TCA cycle genes encoded on pDS15 were aligned and found to be highly homologous with other closely related rhizobial species. S. meliloti cells grown in LBmc express the mdh-sucCDAB operon as one transcript, based on RT-PCR results. Alternative sigma factor sigma54 was not found to have a role in mdh-sucCDAB expression

Abstract:

A total of 200 Rhizobium meliloti isolates were sampled from alfalfa (Medicago sativa L.) nodules in five uninoculated fields throughout Arizona. Dominant strains (≥ 20% nodule occupancy at each site) were identified using plasmid profile analysis and intrinsic antibiotic resistance patterns. The major dominant strains and a commercial strain (102F77b) were evaluated for their N fixing effectiveness in a Leonard jar study. All strains were highly effective, and no significant differences were found (p ≥ 0.05) in shoot weight, root weight, nodule weight, acetylene reduction and total N content
