Thirteen Rhizobium leguminosarum strains previously reported as H2-uptake hydrogenase positive (Hup+) or negative (Hup−) were analyzed for the presence and conservation of DNA sequences homologous to cloned Bradyrhizobium japonicum hup-specific DNA from cosmid pHU1 (M. A. Cantrell, R. A. Haugland, and H. J. Evans, Proc. Natl. Acad. Sci. USA 80:181-185, 1983). The Hup phenotype of these strains was reexamined by determining hydrogenase activity induced in bacteroids from pea nodules. Five strains, including H2 oxidation-ATP synthesis-coupled and -uncoupled strains, induced significant rates of H2-uptake hydrogenase activity and contained DNA sequences homologous to three probe DNA fragments (5.9-kilobase [kb] HindIII, 2.9-kb EcoRI, and 5.0-kb EcoRI) from pHU1. The pattern of genomic DNA HindIII and EcoRI fragments with significant homology to each of the three probes was identical in all five strains regardless of the H2-dependent ATP generation trait. The restriction fragments containing the ...

A 1.9 kb DNA region of Rhizobium leguminosarum biovar viciae strain VF39 capable of promoting microaerobic and symbiotic induction of the Rhizobium meliloti fixN gene was identified by heterologous complementation. Sequence analysis of this DNA region revealed the presence of two complete open reading frames, orf240 and orf114. The deduced amino acid sequence of orf240 showed significant homology to Escherichia coli Fnr and R. meliloti FixK. The major difference between ORF240 and FixK is the presence of 21 N-terminal amino acids in ORF240 that have no counterpart in FixK. A similar protein domain is also present in E. coli Fnr and is essential for the oxygen-regulated activity of this protein. Analysis of the nucleotide sequence upstream of orf240 revealed a motif similar to the NtrA-dependent promoter consensus sequence, as well as two DNA regions resembling the Fnr consensus binding sequence. A Tn5-generated mutant in orf240 lost the ability to induce the R. meliloti fixN-lacZ fusion. ...

The secreted nodulation-signaling protein NodO was purified from the supernatant of cultures of Rhizobium leguminosarum biovar viciae. The native protein has a M(r) of approximately 67,000, suggesting that it exists as a dimer since the DNA sequence predicts a M(r) of 30,002. Pure NodO protein had no protease, pectinase, or cellulase activity, and no binding was observed to lipooligosaccharide nodulation factors. Although NodO is relatively hydrophilic, it appeared to insert into liposomes and was protected by liposomes from proteolytic cleavage. When added to planar lipid bilayers, NodO formed cation-selective channels that allowed the movement of monovalent cations (K+ and Na+) across the membrane. NodO is a Ca(2+)-binding protein; in the presence of high concentrations of Ca2+, channel activity was reduced. We hypothesize that NodO plays a role in nodulation signaling by stimulating uptake of nodulation factors or by forming cation-specific channels that function synergistically with the ...

Summary: The gene nfrX in Azotobacter vinelandii activates transcription of other nif genes in that species. A cosmid containing cloned Rhizobium leguminosarum DNA that corrected the Nif- defect of an nfrX mutant of A. vinelandii was isolated. Following Tn5 transposon mutagenesis of the cosmid in Escherichia coli, mutant derivatives unable to correct the A. vinelandii nfrX mutants were obtained in two separate regions of DNA. In addition, mutations close to one of the nfrX regions conferred a complex phenotype when introduced into the Rhizobium genome by marker exchange. These mutants induced non-fixing nodules on peas, were slow-growing on media with succinate as C source or nitrate as N source and, when present in R. leguminosarum biovar phaseoli, they failed to make melanin, a pigment that is normally synthesized by R. l. bv. phaseoli. The mutated gene, termed melC, was fused to uidA (which encodes β-glucuronidase); it was found that transcription of melC-uidA was enhanced in microaerobic conditions

Homologues of the plasmid replicator gene repC were detected and characterized in a sample of Rhizobium leguminosarum strains. Conserved PCR primers were designed from published sequences of repC; they amplified a fragment of about 750 bp from 39 out of 41 strains tested, and also from several Sinorhizobium strains, including S. meliloti. Restriction endonuclease digestion showed that the PCR product from individual strains, though uniform in size, was often heterogeneous in sequence. PCR products from 24 field isolates of R. leguminosarum from France, Germany and the UK were cloned and partially sequenced from both ends. Phylogenies constructed from the 5′ and 3′ ends (200 bp each) were largely congruent and demonstrated four clearly defined groups plus several unique strains. Published Agrobacterium repC sequences fall within the phylogeny of R. leguminosarum sequences, though not within any of the four groups. Specific pairs of PCR primers were designed for each of the four groups; 29 out of 41 R

The Rhizobium leguminosarum biovar viciae nodulation protein NodO is partially homologous to haemolysin of Escherichia coli and, like haemolysin, is secreted into the growth medium. The NodO protein can be secreted by a strain of E. coli carrying the cloned nodO gene plus the haemolysin secretion genes hlyBD, in a process that also requires the outer membrane protein encoded by tolC. The related protease secretion genes, prtDEF, from Erwinia chrysanthemi also enable E. coli to secrete NodO. The Rhizobium genes encoding the proteins required for NodO secretion are unlinked to nodO and are unlike other nod genes, since they do not require flavonoids or NodO for their expression. Although proteins similar to NodO were not found in rhizobia other than R. leguminosarum bv. viciae, several rhizobia and an Agrobacterium strain containing the cloned nodO gene were found to have the ability to secrete NodO. These observations indicate that a wide range of the Rhizobiaceae have a protein secretion ...

Two mutant derivatives of Rhizobium leguminosarum ANU843 defective in lipopolysaccharide (LPS) were isolated. The LPS of both mutants lacked O antigen and some sugar residues of the LPS core oligosaccharides. Genetic regions previously cloned from another Rhizobium leguminosarum wild-type isolate, strain CFN42, were used to complement these mutants. One mutant was complemented to give LPS that was apparently identical to the LPS of strain ANU843 in antigenicity, electrophoretic mobility, and sugar composition. The other mutant was complemented by a second CFN42 lps genetic region. In this case the resulting LPS contained O-antigen sugars characteristic of donor strain CFN42 and reacted weakly with antiserum against CFN42 cells, but did not react detectably with antiserum against ANU843 cells. Therefore, one of the CFN42 lps genetic regions specifies a function that is conserved between the two R. leguminosarum wild-type isolates, whereas the other region, at least in part, specifies a strain-specific

A gene, cpaA, with similarity to calcium proton antiporters has been identified adjacent to lpcAB in Rhizobium leguminosarum. LpcA is a galactosyl transferase while LpcB is a 2-keto-3-deoxyoctonate transferase, both of which are required to form the lipopolysaccharide (LPS) core in R. leguminosarum. Mutations in lpcAB result in a rough LPS phenotype with a requirement for elevated calcium concentrations to allow growth, suggesting that truncation of the LPS core exposes a highly negatively charged molecule. This is consistent with the LPS core being one of the main sites for binding calcium in the Gram-negative outer membrane. Strain RU1109 (cpaA::Tn5-lacZ) has a normal LPS layer, as measured by silver staining and Western blotting. This indicates that cpaA mutants are not grossly affected in their LPS layer. LacZ fusion analysis indicates that cpaA is constitutively expressed and is not directly regulated by the calcium concentration. Over-expression of cpaA increased the concentration of calcium

In this paper, we present data showing that RosR of R. leguminosarum bv. trifolii 24.2, besides its role in transcriptional regulation of EPS synthesis, is required for successful interaction with clover plants, stress tolerance, motility, and biofilm formation. Both the rosR mutants (Rt2440 and Rt2472) described earlier [23, 30] and the newly isolated Rt2441, bearing a genomic wild type rosR with the regulatory region in addition to the mutated rosR copy, displayed pleiotropic phenotypes. Pleiotropy of the rosR mutants was fully restored in complementation tests using a low-copy plasmid carrying rosR. Interestingly, the Rt2441 mutant showed a negative dominant effect on EPS production, which confirmed the regulatory role of RosR in EPS synthesis. This phenomenon could be explained, to some extent, by negative autoregulation of rosR expression [23], which may be strengthened by the presence of more RosR-boxes binding RosR (Figure 2). As a result, the diminished amount of functional RosR might be ...

Biological experiment was performed (with Complete Random Design (CRD)) by using sterile and non-sterile soil, to investigate Rhizobium leguminosarum isolate ability to enhance fava beans (Vicia faba) plant. The experiment includes: control group (C), fertilizer treatment as group 1 (F), and Rhizobium leguminosarum inoculum treatments as group 2 (R). Fava beans seeds were planted in pots filled with 5 Kg soil (sterile and non-sterile), and after seven weeks of germination, length and weight of plant vegetative part and plant root were measured. The ability of Rhizobium leguminosarum isolate to produce hydrolytic enzymes (chitinase, pectinase, protease, and lipase) was studied. The results show that the isolate was able to produce chitinase, pectinase, protease, and lipase enzymes. Furthermore, the addition of Rhizobium leguminosarum inoculum to fava beans plant increased the length and dry weight of plant vegetative part (20.3% and 51.5% respectively) and also increased the length and dry weight ...

The X-ray crystal structure of the apo-form of the Fur protein from Rhizobium leguminosarum has been solved at 2.7 å resolution. Small-angle X-ray scattering was used to give information on the solution conformation of the protein. The Fur homodimer folds into two domains. The N-terminal domain is formed from the packing of two helix-turn-helix motifs while the C-terminal domain appears primarily to stabilize the dimeric state of the protein. ...

DNA mismatch repair (MMR) is a highly conserved biological pathway that plays a key role in maintaining genomic stability. MMR corrects DNA mismatches generated during DNA replication, thereby preventing mutations from becoming permanent in dividing cells. MMR also suppresses homologous recombination and was recently shown to play a role in DNA damage signaling. Defects in MMR are associated with genome-wide instability, predisposition to certain types of cancer including HNPCC, resistance to certain chemotherapeutic agents, and abnormalities in meiosis and sterility in mammalian systems. The Escherichia coli MMR pathway has been extensively studied and is well characterized. In E. coli, the mismatch-activated MutS-MutL-ATP complex licenses MutH to incise the nearest unmethylated GATC sequence. UvrD and an exonuclease generate a gap. This gap is filled by pol III and DNA ligase. The GATC sites are then methylated by Dam. Several human MMR proteins have been identified based on their homology to ...

The pentose phosphate pathway is a process of glucose turnover that produces NADPH as reducing equivalents and pentoses as essential parts of nucleotides. There are two different phases in the pathway. One is irreversible oxidative phase in which glucose-6P is converted to ribulose-5P by oxidative decarboxylation, and NADPH is generated [MD:M00006]. The other is reversible non-oxidative phase in which phosphorylated sugars are interconverted to generate xylulose-5P, ribulose-5P, and ribose-5P [MD:M00007]. Phosphoribosyl pyrophosphate (PRPP) formed from ribose-5P [MD:M00005] is an activated compound used in the biosynthesis of histidine and purine/pyrimidine nucleotides. This pathway map also shows the Entner-Doudoroff pathway where 6-P-gluconate is dehydrated and then cleaved into pyruvate and glyceraldehyde-3P [MD:M00008 ...

Transmission electron micrograph (TEM) of five nitrogen fixing bacteria Rhizobium leguminosarum, in tissue of a pea plant Pisum sativum. The bacteria are encased in a structure called an infection thread. The thread, made of host cellulose, is the route taken by the bacteria from the initial site of infection in the root hair, through the cortex of the plant, to the cell that initiates the growth of the root nodule. In the nodule the bacteria releases the enzyme nitrogenase, which converts atmospheric nitrogen into a form that the plant can take up. The plant repays the bacteria for this service by providing them with ample food. Magnification: x4620 at 35mm size. - Stock Image B238/0085

Previously described Rhizobium leguminosarum bv. phaseoli mutants elicit nodules on bean without infection thread formation. These mutants were shown to be purine or, in one case, pyrimidine auxotrophs. Each of the seven purine auxotrophs grew normally when supplied the penultimate precursor of inosine, 5-aminoimidazole-4-carboxamide riboside. Four seemed blocked early in the purine pathway, because they were also thiamine auxotrophs. Reversion analysis and genetic complementation using cloned wild-type DNA showed that in each mutant a single mutation was responsible for both the symbiotic defect and purine or pyrimidine auxotrophy. The mutations were mapped to five dispersed chromosomal locations. The previously reported weak Calcofluor staining of these mutants on minimal agar appeared to be caused by partial growth on contaminating nutrients in the agar, rather than deficient exopolysaccharide production. Nodulation by the mutants was not enhanced by supplying purine or pyrimidine compounds

Despite the recognition that Rhizobium leguminosarum sv. viciae is the most common symbiont of Vicia species worldwide, there is no available information on rhizobia nodulating native Vicia species in Sweden. We have therefore studied the genetic diversity and phylogeny of root nodule bacteria isolated from V. cracca, V. hirsuta, V. sepium, V. tetrasperma and V. sylvatica growing in different locations in Sweden as well as an isolate each from V. cracca in Tromso, Norway, and V. multicaulis in Siberia, Russia. Out of 25 isolates sampled from the six Vicia species in 12 different locations, there were 14 different genotypes based on the atpD, recA and nodA gene phylogenies. All isolates were classified into Rhizobium leguminosarum sv. viciae group based on the concatenated atpD and recA phylogeny and the nodA phylogeny. (C) 2016 Elsevier GmbH. All rights reserved.. ...

Procedures based on DNA hybridization and PCR were developed for quality control of Rhizobium inoculants. Inoculants for pea and goats 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 or in combinations of two or three strains. DNA was isolated from 1-g samples of each peat inoculant and analyzed by nonradioactive DNA-DNA hybridization and by PCR. The hybridization probes were total DNAs from pure cultures of R. galegae HAMBI 1207 and R. leguminosarum biovar viciae 16HSA and a 264-bp strain-specific fragment from the genome of R. galegae HAMBI 1174.

UPM Raflatac is broadening its already extensive range of dedicated tire-labeling solutions with the introduction of Syntyre Plus, a polypropylene (PP) film that has been specially designed to withstand the tough challenges of tire labeling applications.

The most important step of this study was to isolate Rhizobium species and determination of their potency for growth factor production. We isolated 260 type bacteria on PCA (Plate Count Agar) media from adjacent soil samples of ten leguminous plants, two non-leguminous plants and control soil (without plant). Then pure cultures of 53 nitrogen fixing bacterial strains were isolated on selective Yeast Extract Mannitol Agar (YEMA) medium. Five isolates (Ma-G1, Ch-H2, Lo-F1, Sh-J1and Ra-I2) were selected as Rhizobium hainanense and better result was regarded in their assessment for production potency of various growth factors. All Rhizobium spp. were able to fix nitrogen in media. Among these isolates, indole acetic acid (IAA) was produced by Ma-G1 and Ra-I2. The exopolysaccharide production rate of Ma-G1 was enhanced expectedly (1.25-fold increase) by treating with IAA. Unfortunately, these five strains were unable to separate soluble phosphorus content from insoluble tri-calcium phosphate (TCP). ...
