Thermostability reinforcement through a combination of thermostability-related mutations of N-carbamyl-D-amino acid amidohydrolase. (1/1949)

For the improvement of N-carbamyl-D-amino acid amidohydrolase (DCase), which can be used for the industrial production of D-amino acids, the stability of DCase from Agrobacterium sp. KNK712 was improved through various combinations of thermostability-related mutations. The thermostable temperature (defined as the temperature on heat treatment for 10 min that caused a decrease in the DCase activity of 50%) of the enzyme which had three amino acids, H57Y, P203E, and V236A, replaced was increased by about 19 degrees C. The mutant DCase, designated as 455M, was purified and its enzymatic properties were studied. The enzyme had highly increased stability against not only temperature but also pH, the optimal temperature of the enzyme being about 75 degrees C. The substrate specificity of the enzyme for various N-carbamyl-D-amino acids was changed little in comparison with that of the native enzyme. Enzymochemical parameters were also measured.  (+info)

Mutation in GDP-fucose synthesis genes of Sinorhizobium fredii alters Nod factors and significantly decreases competitiveness to nodulate soybeans. (2/1949)

We mutagenized Sinorhizobium fredii HH103-1 with Tn5-B20 and screened about 2,000 colonies for increased beta-galactosidase activity in the presence of the flavonoid naringenin. One mutant, designated SVQ287, produces lipochitooligosaccharide Nod factors (LCOs) that differ from those of the parental strain. The nonreducing N-acetylglucosamine residues of all of the LCOs of mutant SVQ287 lack fucose and 2-O-methylfucose substituents. In addition, SVQ287 synthesizes an LCO with an unusually long, C20:1 fatty acyl side chain. The transposon insertion of mutant SVQ287 lies within a 1.1-kb HindIII fragment. This and an adjacent 2.4-kb HindIII fragment were sequenced. The sequence contains the 3' end of noeK, nodZ, and noeL (the gene interrupted by Tn5-B20), and the 5' end of nolK, all in the same orientation. Although each of these genes has a similarly oriented counterpart on the symbiosis plasmid of the broad-host-range Rhizobium sp. strain NGR234, there are significant differences in the noeK/nodZ intergenic region. Based on amino acid sequence homology, noeL encodes GDP-D-mannose dehydratase, an enzyme involved in the synthesis of GDP-L-fucose, and nolK encodes a NAD-dependent nucleotide sugar epimerase/dehydrogenase. We show that expression of the noeL gene is under the control of NodD1 in S. fredii and is most probably mediated by the nod box that precedes nodZ. Transposon insertion into neoL has two impacts on symbiosis with Williams soybean: nodulation rate is reduced slightly and competitiveness for nodulation is decreased significantly. Mutant SVQ287 retains its ability to form nitrogen-fixing nodules on other legumes, but final nodule number is attenuated on Cajanus cajan.  (+info)

The nolL gene from Rhizobium etli determines nodulation efficiency by mediating the acetylation of the fucosyl residue in the nodulation factor. (3/1949)

The nodulation factors (Nod factors) of Rhizobium etli and R. loti carry a 4-O-acetyl-L-fucosyl group at the reducing end. It has been claimed, based on sequence analysis, that NolL from R. loti participates in the 4-O-acetylation of the fucosyl residue of the Nod factors, as an acetyl-transferase (D. B. Scott, C. A. Young, J. M. Collins-Emerson, E. A. Terzaghi, E. S. Rockman, P. A. Lewis, and C. E. Pankhurst. Mol. Plant-Microbe Interact. 9:187-197, 1996). Further support for this hypothesis was obtained by studying the production of Nod factors in an R. etli nolL::Km mutant. Chromatographic and mass spectrometry analysis of the Nod factors produced by this strain showed that they lack the acetyl-fucosyl substituent, having a fucosyl group instead. Acetyl-fucosylation was restored upon complementation with a wild-type nolL gene. These results indicate that the nolL gene determines 4-O-acetylation of the fucosyl residue in Nod factors. Analysis of the predicted NolL polypeptide suggests a transmembranal location and that it belongs to the family of integral membrane transacylases (J. M. Slauch, A. A. Lee, M. J. Mahan, and J. J. Mekalanos. J. Bacteriol. 178:5904-5909, 1996). NolL from R. loti was also proposed to function as a transporter; our results show that NolL does not determine a differential secretion of Nod factors from the cell. We also performed plant assays that indicate that acetylation of the fucose conditions efficient nodulation by R. etli of some Phaseolus vulgaris cultivars, as well as of an alternate host (Vigna umbellata).  (+info)

Metabolic engineering of poly(3-hydroxyalkanoates): from DNA to plastic. (4/1949)

Poly(3-hydroxyalkanoates) (PHAs) are a class of microbially produced polyesters that have potential applications as conventional plastics, specifically thermoplastic elastomers. A wealth of biological diversity in PHA formation exists, with at least 100 different PHA constituents and at least five different dedicated PHA biosynthetic pathways. This diversity, in combination with classical microbial physiology and modern molecular biology, has now opened up this area for genetic and metabolic engineering to develop optimal PHA-producing organisms. Commercial processes for PHA production were initially developed by W. R. Grace in the 1960s and later developed by Imperial Chemical Industries, Ltd., in the United Kingdom in the 1970s and 1980s. Since the early 1990s, Metabolix Inc. and Monsanto have been the driving forces behind the commercial exploitation of PHA polymers in the United States. The gram-negative bacterium Ralstonia eutropha, formerly known as Alcaligenes eutrophus, has generally been used as the production organism of choice, and intracellular accumulation of PHA of over 90% of the cell dry weight have been reported. The advent of molecular biological techniques and a developing environmental awareness initiated a renewed scientific interest in PHAs, and the biosynthetic machinery for PHA metabolism has been studied in great detail over the last two decades. Because the structure and monomeric composition of PHAs determine the applications for each type of polymer, a variety of polymers have been synthesized by cofeeding of various substrates or by metabolic engineering of the production organism. Classical microbiology and modern molecular bacterial physiology have been brought together to decipher the intricacies of PHA metabolism both for production purposes and for the unraveling of the natural role of PHAs. This review provides an overview of the different PHA biosynthetic systems and their genetic background, followed by a detailed summation of how this natural diversity is being used to develop commercially attractive, recombinant processes for the large-scale production of PHAs.  (+info)

Sequence and molecular analysis of the Rhizobium etli glsA gene, encoding a thermolabile glutaminase. (5/1949)

We sequenced a 2.1 kb fragment of DNA carrying the structural glsA gene, which codes for the Rhizobium etli thermolabile glutaminase (A). The glsA gene complements the R. etli LM16 mutant that lacks glutaminase A activity, and is expressed in the heterologous host Sinorhizobium meliloti. The deduced amino acid sequence consists of 309 residues, with a calculated molecular mass of 33 kDa. The amino acid sequence shares 53% and 43% identity with two hypothetical glutaminases of E. coli; 42% identity with liver-type; 38% identity with kidney-type glutaminase; 41% and 40% identity hypothetical glutaminases of Bacillus subtilis; and 41% and 37% identity with two putative glutaminases of Caenorhabditis elegans. The glsA gene represents the first glutaminase gene cloned and sequenced in prokaryotes.  (+info)

Isolation and characterization of the catalase gene from Rhizobium sp. SNU003, a root nodule symbiont of Canavalia lineata. (6/1949)

A catalase gene from Rhizobium sp. SNU003, a root nodule symbiont of Canavalia lineata, was cloned and its nucleotide sequence was determined. The Rhizobium DNA of about 280 bp was amplified using two PCR primers synthesized from the conserved sequences of the type I catalase gene. The nucleotide sequence of the amplified fragment revealed three regions that were conserved in the catalase, showing it as being part of the catalase gene. A genomic Southern hybridization using this fragment as a probe showed that the 5.5 kb PstI, 1.8 kb EcoRI, and 0.7 kb StyI fragments hybridized strongly with the probe. The Rhizobium genomic library constructed into the EMBL3 vector was screened, and one catalase clone was selected. The nucleotide sequence of the 5.5 kb PstI fragment from the clone revealed an open reading frame of 1455 bp, encoding a polypeptide of 485 amino acids with a molecular mass of 54,958 Da and a pI of 6.54. The predicted amino acid sequence of the catalase is 66.3% identical to that of Bacteroides fragilis, but was only 53.3% identical to the Rhizobium meliloti catalase.  (+info)

Rhizobium sp. strain NGR234 and R. fredii USDA257 share exceptionally broad, nested host ranges. (7/1949)

Genetically, Rhizobium sp. strain NGR234 and R. fredii USDA257 are closely related. Small differences in their nodulation genes result in NGR234 secreting larger amounts of more diverse lipo-oligosaccharidic Nod factors than USDA257. What effects these differences have on nodulation were analyzed by inoculating 452 species of legumes, representing all three subfamilies of the Leguminosae, as well as the nonlegume Parasponia andersonii, with both strains. The two bacteria nodulated P. andersonii, induced ineffective outgrowths on Delonix regia, and nodulated Chamaecrista fasciculata, a member of the only nodulating genus of the Caesalpinieae tested. Both strains nodulated a range of mimosoid legumes, especially the Australian species of Acacia, and the tribe Ingeae. Highest compatibilities were found with the papilionoid tribes Phaseoleae and Desmodieae. On Vigna spp. (Phaseoleae), both bacteria formed more effective symbioses than rhizobia of the "cowpea" (V. unguiculata) miscellany. USDA257 nodulated an exact subset (79 genera) of the NGR234 hosts (112 genera). If only one of the bacteria formed effective, nitrogen-fixing nodules it was usually NGR234. The only exceptions were with Apios americana, Glycine max, and G. soja. Few correlations can be drawn between Nod-factor substituents and the ability to nodulate specific legumes. Relationships between the ability to nodulate and the origin of the host were not apparent. As both P. andersonii and NGR234 originate from Indonesia/Malaysia/Papua New Guinea, and NGR234's preferred hosts (Desmodiinae/Phaseoleae) are largely Asian, we suggest that broad host range originated in Southeast Asia and spread outward.  (+info)

Autoinducer binding by the quorum-sensing regulator TraR increases affinity for target promoters in vitro and decreases TraR turnover rates in whole cells. (8/1949)

TraR is an Agrobacterium transcriptional regulator whose activity requires the pheromone N-3-oxooctanoyl-L-homoserine lactone. TraR was purified as a complex with the pheromone and contained one pheromone molecule per protein monomer. TraR-pheromone complexes bound to a single DNA site and activated two promoters that flank this site. Promoter expression was elevated 30-fold by using a supercoiled template. Pheromone binding increased the affinity of TraR for this binding site. Pheromone also increased TraR abundance in vivo by causing a 20-fold decrease in TraR turnover rates.  (+info)

Rhizobium, Agrobacterium and Allorhizobium are genera within the bacterial family Rhizobiaceae, together with Sinorhizobium. The species of Agrobacterium, Agrobacterium tumefaciens (syn. Agrobacterium radiobacter), Agrobacterium rhizogenes, Agrobacterium rubi and Agrobacterium vitis, together with Allorhizobium undicola, form a monophyletic group with all Rhizobium species, based on comparative 16S rDNA analyses. Agrobacterium is an artificial genus comprising plant-pathogenic species. The monophyletic nature of Agrobacterium, Allorhizobium and Rhizobium and their common phenotypic generic circumscription support their amalgamation into a single genus, Rhizobium. Agrobacterium tumefaciens was conserved as the type species of Agrobacterium, but the epithet radiobacter would take precedence as Rhizobium radiobacter in the revised genus. The proposed new combinations are Rhizobium radiobacter, Rhizobium rhizogenes, Rhizobium rubi, Rhizobium undicola and Rhizobium vitis.

Evidence for plasmid- and chromosome-borne multiple nif genes in Rhizobium fredii. - Semantic ScholarEvidence for plasmid- and chromosome-borne multiple nif genes in Rhizobium fredii. - Semantic Scholar
Rhizobium fredii is a fast-growing rhizobium isolated from the primitive Chinese soybean cultivar Peking and from the wild soybean Glycine soja. This rhizobium harbors nif genes on 150- to 200-megadalton plasmids. By passage on acridine orange plates, we obtained a mutant of R. fredii USDA 206 cured of the 197-megadalton plasmid (USDA 206C) which carries both nif and nod genes. This strain, however, has retained its symbiotic effectiveness. Probing EcoRI digests of wild-type and cured plasmid DNA with a 2.2-kilobase nif DH fragment from Rhizobium meliloti has shown four homologous fragments in the wild-type strain (4.2, 4.9, 10, and 11 kilobases) and two fragments in the cured strain (4.2 and 10 kilobases). EcoRI digests of total DNA show four major bands of homology (4.2, 4.9, 5.8, and 13 kilobases) in both the wild-type and cured strains. The presence of major bands of homology in the total DNA not present in the plasmid DNA indicated chromosomal nif genes. Probing of HindIII digests of total and

A family of activator genes regulates expression of Rhizobium meliloti nodulation genes. | GeneticsA family of activator genes regulates expression of Rhizobium meliloti nodulation genes. | Genetics
Nodulation (nod) gene expression in Rhizobium meliloti requires plant inducers and the activating protein product of the nodD gene. We have examined three genes in R. meliloti which have nodD activity and sequence homology. These three nodD genes are designated nodD1, nodD2 and nodD3, and have distinctive properties. The nodD1 gene product activates expression of the nodABC operon, as measured by a nodC-lacZ fusion or by transcript analysis, in the presence of crude seed or plant wash or the inducer, luteolin. The nodD3 gene product can cause a high basal (uninduced) level of nodC-lacZ expression and nodABC transcripts which is relatively unaffected by inducers. The effect of nodD3 is dependent on the presence of another gene, syrM (symbiotic regulator). By primer extension analysis we determined that the transcription start site is the same for nodD1 plus luteolin or nodD3-syrM mediated expression of nodA and nodH mRNAs. syrM also enhances the expression of another symbiotically important ...

In vitro sulfotransferase activity of Rhizobium meliloti NodH protein: lipochitooligosaccharide nodulation signals are sulfated...In vitro sulfotransferase activity of Rhizobium meliloti NodH protein: lipochitooligosaccharide nodulation signals are sulfated...
The Rhizobium common nod gene products NodABC are involved in the synthesis of the core lipochitooligosaccharide (Nod factor) structure, whereas the products of the host-specific nod genes are necessary for diverse structural modifications, which vary in different Rhizobium species. The sulfate group attached to the Rhizobium meliloti Nod signal is necessary for activity on the host plant alfalfa, while its absence renders the Nod factor active on the non-host plant vetch. This substituent is therefore a major determinant of host specificity. The exact biosynthetic pathway of Nod factors has not been fully elucidated. In particular, it is not known why some chemical modifications are introduced with high fidelity whereas others are inaccurate, giving rise to a family of different Nod factor structures produced by a single Rhizobium strain. Using protein extracts and partially purified recombinant NodH protein obtained from Escherichia coli expressing the R. meliloti nodH gene, we demonstrate ...

The role of soil microorganisms in plant growth, nutrient utilization, drought tolerance as well as biocontrol activity cannot be over-emphasized, especially in this era when food crisis is a global challenge. This research was therefore designed to gain genomic insights into plant growth promoting (PGP) Rhizobium species capable of enhancing soybean (Glycine max L.) seeds germination under drought condition. Rhizobium sp. strain R1, Rhizobium tropici strain R2, Rhizobium cellulosilyticum strain R3, Rhizobium taibaishanense strain R4 and Ensifer meliloti strain R5 were found to possess the entire PGP traits tested. Specifically, these rhizobial strains were able to solubilize phosphate, produce exopolysaccharide (EPS), 1-aminocyclopropane-1-carboxylate (ACC), siderophore and indole-acetic-acid (IAA). These strains also survived and grew at a temperature of 45 °C and in an acidic condition with a pH 4. Consequently, all the Rhizobium strains enhanced the germination of soybean seeds (PAN 1532 R) under

Monoclonal antibodies were used as cytochemical markers to study surface interactions between endosymbiotic Rhizobium bacteroids from pea root nodules and the encircling peribacteroid membranes, which are of plant origin. Monoclonal antibodies that react with Rhizobium lipopolysaccharide (LPS) or with a plant membrane glycoprotein were used as markers for material from the bacteroid outer membrane or the peribacteroid membrane, respectively. Membrane-enclosed bacteroids were isolated from nodule homogenates by sucrose gradient centrifugation, and the encircling peribacteroid membrane was released by mild osmotic shock treatment. Using an immunochemical technique (sandwich ELISA), it was shown that 1-5% of the LPS antigen released into the peribacteroid fraction by mild osmotic shock treatment was physically associated with peribacteroid membrane through a detergent-sensitive linkage. This association could be visualized when freshly prepared peribacteroid material was immobilized on gold grids ...

Rhizobium - WikipediaRhizobium - Wikipedia
Rhizobium is a genus of Gram-negative soil bacteria that fix nitrogen. Rhizobium species form an endosymbiotic nitrogen-fixing association with roots of legumes and Parasponia. The bacteria colonize plant cells within root nodules, where they convert atmospheric nitrogen into ammonia and then provide organic nitrogenous compounds such as glutamine or ureides to the plant. The plant, in turn, provides the bacteria with organic compounds made by photosynthesis. This mutually beneficial relationship is true of all of the rhizobia, of which the Rhizobium genus is a typical example. Beijerinck in the Netherlands was the first to isolate and cultivate a microorganism from the nodules of legumes in 1888. He named it Bacillus radicicola, which is now placed in Bergeys Manual of Determinative Bacteriology under the genus Rhizobium. Rhizobium forms a symbiotic relationship with certain plants such as legumes, fixing nitrogen from the air into ammonia, which acts as a natural fertilizer for the plants. ...

Agrobacterium infection, which is widely used to generate transgenic plants, is often accompanied by T-DNA-linked mutations and transpositions in flowering plants. It is not known if Agrobacterium infection also affects the rates of point mutations, somatic homologous recombinations (SHR) and frame-shift mutations (FSM). We examined the effects of Agrobacterium infection on five types of somatic mutations using a set of mutation detector lines of Arabidopsis thaliana. To verify the effect of secreted factors, we exposed the plants to different Agrobacterium strains, including wild type (Ach5), its derivatives lacking vir genes, oncogenes or T-DNA, and the heat-killed form for 48 h post-infection; also, for a smaller set of strains, we examined the rates of three types of mutations at multiple time-points. The mutation detector lines carried a non-functional β-glucuronidase gene (GUS) and a reversion of mutated GUS to its functional form resulted in blue spots. Based on the

Phenotypic and Genotypic Diversity of Rhizobia:: volume 1 | BenthamSciencePhenotypic and Genotypic Diversity of Rhizobia:: volume 1 | BenthamScience
Rhizobia are composed of specific groups of bacteria that have the ability to induce symbiotic nitrogen-fixing nodules on the roots or stems of leguminous plants. Rhizobia have attracted a great attention for more than 4 decades because of their enormous agricultural and economic value in sustainable agriculture. Up to the present time, many legumes have been found to be nodulated by several rhizobial species in diverse taxonomic groups. An assessment of rhizobial diversity provides pivotal information in understanding the horizontal gene transfer among bacterial genera and species, the bacterial evolution and the symbiotic effectiveness. The classification of rhizobia is becoming increasingly complex and is revised periodically because of new findings that propose new genera and new species. Phenotypic and Genotypic Diversity of Rhizobia presents the application of conventional and molecular analyses, including numerical analysis, enzyme patterns, serological studies, plasmid profile, ...

FINAL DIAGNOSIS: AGROBACTERIUM RADIOBACTER. CONTRIBUTORS NOTE:. The genus Agrobacterium are aerobic, gram negative, peritrichous bacilli which are mainly plant pathogens found in soil all over the world. Agrobacterium tumefaciens and Agrobacterium radiobacter are two species that have been isolated from human specimens although only A. radiobacter is associated with clinical symptoms (1).. Despite A. radiobacters association with significant clinical symptoms, it is considered to be of low virulence and there have been no reports of mortality from the organism alone. The only difference between the two species is the presence of a tumor-producing plasmid, the Ti plasmid, in A. tumefaciens which results in a tumorous growth in plants (2).. Agrobacterium radiobacter is infrequently recognized in clinical specimens however it has been associated with immunocompromised patients that have implanted medical devices or transcutaneous catheters (1,3,4).

Isolation and characterization of Rhizobium spp. and determination of their potency for growth factor productionIsolation and characterization of Rhizobium spp. and determination of their potency for growth factor production
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). ...

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. The total DNA probes distinguished inoculants containing R. galegae or R. leguminosarum, and the strain-specific probe distinguished inoculants containing R. galegae HAMBI 1174. The hybridization results for R. galegae were verified in a PCR ...

ASMscience | The Agrobacterium Ti PlaASMscience | The Agrobacterium Ti Pla
Agrobacterium species that are pathogenic on plants, including Agrobacterium tumefaciens, A. vitis, A. rubi, and A. rhizogenes, all carry megaplasmids. By contrast, nonpathogenic strains either lack these plasmids entirely or carry mutant forms of plasmids. A strict requirement of the Ti plasmid for virulence was established through mutational analyses and by a demonstration that the introduction of Ti plasmids into Rhizobium or Phyllobacterium spp. converts these nonpathogenic species into tumor-inducing pathogens ( 2 , 3 ). Ti plasmids induce a disease called crown gall, which is typified by the formation of undifferentiated plant tumors at the plant crown (the subterranean-to-aerial transition zone). The related root-inducing or Ri megaplasmids carried by A. rhizogenes instead induce hairy root disease, which is typified by the formation of entangled masses of roots at the infection site ( 4 ).

Rhizobium rhizogenes - WikipediaRhizobium rhizogenes - Wikipedia
Rhizobium rhizogenes (formerly Agrobacterium rhizogenes) is a Gram-negative soil bacterium that produces hairy root disease in dicotyledonous plants. R. rhizogenes induces the formation of proliferative multiple-branched adventitious roots at the site of infection, so-called hairy roots. In the rhizosphere, plants may suffer from wounds by soil pathogens or other sources. This leads to the secretion of phenolic compounds like acetosyringone which have chemotactic effects that attract the bacteria. Under such conditions, certain bacterial genes are turned on leading to the transfer of its tDNA from its root-inducing plasmid (Ri plasmid) into the plant through the wound. After integration and expression, in vitro or under natural conditions, the hairy root phenotype is observed, which typically includes overdevelopment of a root system that is not completely geotropic, and altered (wrinkled) leaf morphology, if leaves are present. Bacterial genes may be retained within the plant. The hairy roots ...

Genetic diversity and symbiotic efficiency of population of rhizobia of Phaseolus vulgaris L. in Brazil - Semantic ScholarGenetic diversity and symbiotic efficiency of population of rhizobia of Phaseolus vulgaris L. in Brazil - Semantic Scholar
The genetic diversity and symbiotic efficiency among indigenous rhizobia isolates obtained from native field with or without organic fertilization and superficial mineral fertilization were investigated. Eighty-six indigenous rhizobia were isolated from these fields using four common bean varieties as trap-host. The common bean varieties Mexico 309 and Rio Tibagi selected the most efficient rhizobia strains because they showed the best yields and N contents results. The genetic characterization of 36 rhizobia isolates was evaluated by using electrophoretic profiles of amplification products using primers ERIC1-R and ERIC-2. Our results demonstrated that besides the large diversity in the indigenous rhizobial community, the genotype of the trap-host probably influences the selection of the most efficient strains.

Rhizobium forms a symbiotic relationship with certain plants such as legumes, fixing nitrogen from the air into ammonia, which acts as a natural fertilizer for the plants. Current research is being conducted by Agricultural Research Service microbiologists to discover a way to use Rhizobiums biological nitrogen fixation. This research involves the genetic mapping of various rhizobial species with their respective symbiotic plant species, like alfalfa or soybean. The goal of this research is to increase the plants productivity without using fertilizers.[3]. In molecular biology, Rhizobium has also been identified as a contaminant of DNA extraction kit reagents and ultrapure water systems, which may lead to its erroneous appearance in microbiota or metagenomic datasets.[4] The presence of nitrogen fixing bacteria as contaminants may be due to the use of nitrogen gas in ultra-pure water production to inhibit microbial growth in storage tanks.[5]. ...

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. ...

Lirias: Secretion of the Rhizobium leguminosarum nodulation protein NodO by haemolysin-type systemsLirias: Secretion of the Rhizobium leguminosarum nodulation protein NodO by haemolysin-type systems
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 ...

Alfalfa and tobacco cells react differently to chitin oligosaccharides and Sinorhizobium meliloti nodulation factors
Alfalfa (Medicago sativa L.) suspension cultures respond to yeast elicitors with a strong alkalinization of the culture medium, a transient synthesis of activated oxygen species, and typical late defence reactions such as phytoalexin accumulation and increased peroxidase activity. The alkalinization reaction as well as the oxidative burst were also observed when tobacco (Nicotiana tabacum L.) cell-suspension cultures were treated with yeast elicitors. Depending on the degree of polymerization, N-acetyl chitin oligomers induced the alkalinization response in both plant cell-suspension cultures, while only tobacco cell cultures developed an oxidative burst. Suspension-cultured tobacco cells responded to Sinorhizobium meliloti nodulation factors with a maximal alkalinization of 0.25 pH units and a remarkable oxidative burst. In contrast, addition of Sinorhizobium meliloti nodulation factors to suspension-cultured alfalfa cells induced a slight acidificatiton of the culture medium, instead of an ...

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 ...

TY - JOUR. T1 - Identification of dominant indigenous Rhizobium meliloti by plasmid profiles and intrinsic antibiotic resistance. AU - Shishido, M.. AU - Pepper, I. L.. PY - 1990. Y1 - 1990. N2 - Yields of alfalfa (Medicago sativa L.) in irrigated production agriculture in the southwest U.S.A. varies widely, but is generally higher than in other areas of the U.S.A. Since nitrogen fertilizer is rarely applied, high yields are likely to be due in part to biological N2 fixation in the symbiotic association between alfalfa and Rhizobium meliloti. Dominant types of R. meliloti responsible for N2 fixation were identified from nodule isolates collected from five locations throughout the state of Arizona, which were not known to have been inoculated. The locations were sampled in the winter of 1987 and the summer of 1988. The dominant types (≥20% nodule occupancy at each sampling site) were identified through plasmid profile analysis and intrinsic antibiotic resistance patterns. Four types were found ...

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

Rhizobia comprise a group of α- and β-proteobacteria known for their ability to establish symbioses with several leguminous species. The rhizobium-legume interaction, characterized by an exchange of signal molecules from both partners, culminates in the formation of specific structures, called nodules, where biological nitrogen fixation takes place [1-5]. This molecular dialogue begins with the exudation of flavonoids by the host legume roots that are recognized by a LysR-type transcriptional regulator in the bacterium, the NodD protein, which triggers the expression of the so-called nodulation (nod) genes by binding to specific sequences, nod boxes (NB), located upstream of these genes. Their cognate enzymes are implied in the production of lipochitooligosaccharides, also known as Nod factors (NF), which in turns induce the formation of root nodule primordia and play an essential role in the infection process. A part from flavonoids, other rhizobial nod gene inducers have been identified, ...

We have physically and genetically characterized 20 symbiotic and 20 auxotrophic mutants of Rhizobium meliloti, the nitrogen-fixing symbiont of alfalfa (Medicago sativa), isolated by transposon Tn5 mutagenesis. A suicide plasmid mutagenesis procedure was used to generate TN-5-induced mutants, and both auxotrophic and symbiotic mutants were found at a frequency of 0.3% among strains containing random TN5 insertions. Two classes of symbiotic mutants were isolated: 4 of the 20 formed no nodules at all (Nod-), and 16 formed nodules which failed to fix nitrogen (Fix-). We used a combination of physical and genetic criteria to determine that in most cases the auxotrophic and symbiotic phenotypes could be correlated with the insertion of a single Tn5 elements. Once the Tn5 element was inserted into the R. meliloti genome, the frequency of its transposition to a new site was approximately 10-8 and the frequency of precise excision was less than 10-9. In approximately 25% of the mutant strains, phage ...

Identification of a putative LPS-associated cation exporter from Rhizobium leguminosarum bv. viciae. - Oxford Neuroscience
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

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

Energy coupling in soybean bacteroidsEnergy coupling in soybean bacteroids
Biological dinitrogen fixation by Rhizobium spp. in the root nodules of leguminous plants such as soybean is of considerable agronomic importance. Biological dinitrogen fixation is ATP- and reductant-dependent; between 12 and 30 mol of ATP are required per mol of dinitrogen reduced [1]. All free-living rhizobia are aerobic although some strains will also grow anaerobically with nitrate as the terminal electron acceptor [2] ; ATP and reductant are generated during the oxidation of an exogenously supplied carbon source. In the bacteroids within the root nodule the exogenous carbon source (photosynthate) is derived from photosynthetic CO₂ fixation by the host plant. The identity of the carbon source(s) oxidised by the bacteroids in vivo has not yet been confirmed although sucrose is the major photosynthetic product translocated to the root nodules [3]. As dinitrogen fixation represents a drain on the photosynthetic supply [4,5] and since the supply of photosynthate is probably one of the major ...

Rhizobium - Special Bacteria For LegumesRhizobium - Special Bacteria For Legumes
Symbiotic nitrogen fixation of Rhizobia with leguminous crops accounts for 20% of the global nitrogen cycle. Rhizobium inoculation is always needed when certain new leguminous crops are introduced to new areas or regions. In addition to supply nitrogen to leguminous crops, they also spare soil nitrogen to succeeding crops. Thus the legume fixed nitrogen is important in sustaining pulse production.

dead zones. Toxic algae fills these dead zones, taking up oxygen and killing fish and plants in the process.. In charge of the BYU study is Paul Skip Price, a postdoctoral fellow at BYU. He and his team have found that rhizobia bacteria might be the key in allowing plants to process nitrogen naturally, without nitrogen-based fertilizers.. Price said about 80 percent of the atmosphere is nitrogen, but it is in a form that plants cannot use. However, rhizobia and plants can work together to become mutually beneficial, a process known as symbiosis.. By doing this and providing nitrogen naturally, you wont have to add more fertilizers which cause more runoff, Price said.. The objective of Prices study is to discover the types of rhizobia that will work in conjunction with plants.. One of the problems we have now is we dont know what makes a good rhizobia for the soil, Price said. And so thats what were studying, is how to improve the rhizobia for the plant.. Price has discovered that ...

How much fluorine is too much fluorine? | Science CodexHow much fluorine is too much fluorine? | Science Codex
For most of us, our closest encounter with the element fluorine is likely to be our toothpaste or a municipal water supply with added fluoride.. But excess fluorine can be a problem. For example, high levels of fluorine in the soil can hurt plants. Fluorine in soils may also affect microbes and other organisms higher along the food chain.. A new study explored whether soil fluorine levels in New Zealand are high enough to hurt a specific microbe called Rhizobium.. Rhizobium bacteria live in root nodules of legume plants, like beans and lentils. These bacteria fix atmospheric nitrogen, making the nutrients into a form the host plant can use.. Nitrogen fixation by Rhizobia means farmers need to use less nitrogen fertilizer. That can save significant costs.. If soil fluorine levels become high enough to hurt Rhizobia, it could impact the legume crops the bacteria help support.. In addition, pastures for grazing livestock often contain clover, another legume. High fluorine levels could harm ...

Age of peat-based lupin and chickpea inoculants in relation to quality and efficacy - Murdoch University Research RepositoryAge of peat-based lupin and chickpea inoculants in relation to quality and efficacy - Murdoch University Research Repository
Extension of the current 12-month expiry of rhizobial inoculants in Australia to 18 months would have commercial benefits for the manufacturers and resellers. The dilemma, however, is that numbers of rhizobia in the inoculants decline over time and individual cells may lose efficacy. The research undertaken in this study shows the effect of lupin and chickpea inoculant age (i.e. 0, 6, 12, 15 and 18 months old) on numbers of rhizobia, rhizobial cell characteristics and efficacy. For the latter, assessments included colony size on plates, survival on inoculated beads, and infectiveness and effectiveness in field experiments at 3 sites.. Assessment of commercially produced inoculants at the Australian Legume Inoculants Research Unit (ALIRU) laboratory indicated that, on average, chickpea and lupin inoculants had counts of about log10 9.6 when fresh, delivering ,log10 6 rhizobia/seed. At 12 months, the average counts had fallen to log10 9.4, delivering slightly less than log10 6 rhizobia/seed. By 18 ...

Biological nitrogen fixation (BNF) by plants and its bacterial associations represent an important natural system for capturing atmospheric dinitrogen (N2) and processing it into a reactive form of nitrogen through enzymatic reduction. The study of BNF in non-leguminous plants has been difficult compared to nodule-localized BNF in leguminous plants because of the diverse sites of N2 fixation in non-leguminous plants. Identification of the involved N2-fixing bacteria has also been difficult because the major nitrogen fixers were often lost during isolation attempts. The past 20 years of molecular analyses has led to the identification of N2 fixation sites and active nitrogen fixers in tissues and the rhizosphere of non-leguminous plants. Here, we examined BNF hotspots in six reported non-leguminous plants. Novel rhizobia and methanotrophs were found to be abundantly present in the free-living state at sites where carbon and energy sources were predominantly available. In the carbon-rich apoplasts of
