Pongamia pinnata has an added advantage of N2-fixing ability and tolerance to stress conditions as compared with other biodiesel crops. It harbours "rhizobia" as an endophytic bacterial community on its root nodules. A gram-negative, nonmotile, fast-growing, rod-shaped, bacterial strain VKLR-01(T) was isolated from root nodules of Pongamia that grew optimal at 28°C, pH 7.0 in presence of 2% NaC...

We have cloned and sequenced three genes from Rhizobium meliloti (Sinorhizobium meliloti) that are involved in sulfate activation for cysteine biosynthesis. Two of the genes display homology to the Escherichia coli cysDN genes, which code for an ATP sulfurylase (EC 2.7.7.4). The third gene has homology to the E. coli cysH gene, a 3'-phosphoadenosine-5'-phosphosulfate (PAPS) reductase (EC 1.8.99...

Soybean cells in suspension culture were inhibited in their growth by mixed culture with Rhizobium japonicum 5033. Rhizobium cells had the ability to adsorb on the surface of soybean cells. Cell envelope prepared from Rhizobium by sonic oscillation inhibited the growth of soybean cells. The growth-inhibiting activity of the cell envelope was depressed by beta-glucosidase, KIO(4), urea, sodium c...

The bacterial host ranges of the conjugatively self-transmissible IncN group plasmid pCU1 and its mobilizable miniderivative, pCU785, were examined. Species of the gram-negative purple bacteria were chosen for this study. Conjugative mobilization of pCU785 into a wide variety of bacteria was facilitated by the presence of oriT of the broad-host-range plasmid RK2 in pCU785. Although the host ran...

Eagon, R. G. (University of Georgia, Athens). Bacterial dissimilation of l-fucose and l-rhamnose. J. Bacteriol. 82:548-550. 1961.-Of 33 microorganisms screened for the ability to utilize the methylpentoses, l-fucose and l-rhamnose, 18 species utilized one or both methylpentoses. The majority of the bacterial species capable of utilizing these methylpentoses did so by isomerization of the methyl...

in order to study of the effects of hydro-osmo priming, bio-priming (biological fertilizer (barvar-2) and inoculation with rhizobium japonicum bacteria) on growth & yield of dpx cultivar of soybean (glycine max l.), an experiment was carried out as factorial based on a randomized complete block design (rcbd) with 4 replications in agriculture research station of shahrood university of technolog...

Background: Effectiveness of Rhizobium inoculation is determined by common bean genotypes. Environmental factors also affect common bean genotypes-Rhizobium-symbiosis. The effect of common bean genotypes-Rhizobium strains-environment interaction on nodulation and common bean production is not well studied. Three genotypes (Dursitu, Gofta, and Kufanzik) and eight selected isolates of common bean...

We have determined the structures of Nod factors produced by strains representative of Sinorhizobium teranga bv. acaciae and the so-called cluster U from the Rhizobium loti branch, two genetically different symbionts of particular Acacia species. Compounds from both strains were found to be similar, i.e., mainly sulfated, O carbamoylated, and N methylated, indicating a close relationship betwee...
