A mildly acid-sensitive mutant of Rhizobium leguminosarum bv. viciae WSM710 (WR6-35) produced colonies which were more mucoid in phenotype than the wild-type. Strain WR6-35 contained a single copy of Tn5 and the observed mucoid phenotype, acid sensitivity and Tn5-induced kanamycin resistance were 100% co-transducible using phage RL38. WR6-35 produced threefold more exopolysaccharide (EPS) than the wild-type in minimal medium devoid of a nitrogen source. EPS produced by the mutant and the wild… Expand
Genetic characterization of the Pss region and the role of PssS in exopolysaccharide production and symbiosis of Rhizobium leguminosarum bv. trifolii with clover
TLDR
Transcriptional levels of particular pss genes differed significantly; the genes encoding glycosyltransferases and enzymes modifying EPS have promoters of weak activities, whereas those encoding proteins involved in EPS polymerization and export possess stronger promoters. Expand
Mutation in the pssA Gene Involved in Exopolysaccharide Synthesis Leads to Several Physiological and Symbiotic Defects in Rhizobium leguminosarum bv. trifolii
TLDR
The data of this study indicate that the protein product of the pssA gene is not only involved in EPS synthesis, but also required for proper functioning of Rhizobium leguminosarum bv. Expand
Modulation of rosR Expression and Exopolysaccharide Production in Rhizobium leguminosarum bv. trifolii by Phosphate and Clover Root Exudates
TLDR
The synthesis of EPS and biofilm formation decreased at high phosphate concentrations, but increased in the presence of clover root exudates, indicating a complex regulation of these processes. Expand
The Rhizobium leguminosarum bv. trifolii RosR: transcriptional regulator involved in exopolysaccharide production.
TLDR
A rosR frame-shift mutant of R. trifolii formed dry, wrinkled colonies and induced nodules on clover, but did not fix nitrogen, and a homolog of transcriptional regulators belonging to the family of Ros/MucR proteins increased exopolysaccharide production. Expand
The Rhizobium leguminosarum bv. trifolii pssB gene product is an inositol monophosphatase that influences exopolysaccharide synthesis
TLDR
The mutation in PssB caused EPS overproduction, and introduction of pssB into the wild-type TA1 strain reduced EPS synthesis, and changes in the level of EPS production were correlated with a non-nitrogen-fixing phenotype of rhizobia. Expand
Expression of the Rhizobium leguminosarum bv. trifolii pssA Gene, Involved in Exopolysaccharide Synthesis, Is Regulated by RosR, Phosphate, and the Carbon Source
TLDR
It was found that the pssA gene is an important target for regulation of this biosynthetic pathway and cyclic AMP (cAMP) receptor protein (CRP) and two cAMP-CRP boxes located upstream of the P1 are required for this upregulation. Expand
Characterization and identification of environmental stress tolerance mechanisms in Sinorhizobium meliloti
TLDR
The use of bacterial genetics to characterize how metabolism and the production of polysaccharides affect the survival of strains under salt and acidic pH stress is described, consistent with the hypothesis that mechanisms used by rhizobia to tolerate diverse environmental conditions directly interact with the symbiotic process. Expand
ActP controls copper homeostasis in Rhizobium leguminosarum bv. viciae and Sinorhizobium meliloti preventing low pH‐induced copper toxicity
TLDR
It is shown that copper homeostasis is an essential mechanism for the acid tolerance of these root nodule bacteria since it prevents this heavy metal from becoming overtly toxic in acidic conditions. Expand
Dissecting the Acid Stress Response of Rhizobium tropici CIAT 899
TLDR
The acid stress response of R. tropici CIAT899 is versatile: genes encoding response regulators and membrane transporters, enzymes involved in amino acid and carbohydrate metabolism and proton extrusion, in addition to several hypothetical genes are found. Expand

Rhizobium leguminosarum exopolysaccharide mutants: biochemical and genetic analyses and symbiotic behavior on three hosts
TLDR
The results support earlier suggestions that successful symbiosis with peas or clovers requires that rhizobia be capable of acidic exopolysaccharide production, whereas symbiotics with beans does not have this requirement. Expand

TLDR
A firm and extensive correlation is established between the ability of Rhizobium to produce a particular polysaccharide and symbiotic proficiency and the exopolysaccharides involved in wild-type nodule invasion. Expand
Rhizobium meliloti mutants that overproduce the R. meliloti acidic calcofluor-binding exopolysaccharide
TLDR
Two loci, exoR and exoS, that affect the regulation of synthesis of this exopolysaccharide were identified by screening for derivatives of strain Rm1021 that formed mucoid colonies that fluoresced extremely brightly under UV light when grown on medium containing Calcofluor. Expand
Acid tolerance in Rhizobium meliloti strain WSM419 involves a two-component sensor-regulator system.
TLDR
Data implicate a two-component sensor-regulator protein pair in acid tolerance in R. meliloti and suggest their involvement in pH sensing and/or response by these bacteria. Expand
An essential role for actA in acid tolerance of Rhizobium meliloti.
TLDR
The reconstructed wild-type actA gene complemented the low pH- and copper-sensitive phenotype of TG2-6 and showed that actA is constitutively expressed at pH 5.8 and 7.0. Expand
Mutations conferring acid sensitivity in the acid-tolerant strains Rhizobium meliloti WSM419 and Rhizobium leguminosarum biovar viciae WSM710
TLDR
The genetic basis of acid-tolerance in rhizobia is being investigated by the isolation and molecular characterisation of Tn5-induced acid-sensitive mutants and preliminary hybridization studies suggest that there are sequences homologous to the act206 region present in several species of bacteria. Expand
Unusual structure of the exopolysaccharide of Rhizobium leguminosarum bv. viciae strain 248.
TLDR
R. viciae strain 248, cured of its Sym plasmid pRL1JI, synthesised an exopolysaccharide in which the sites and degree of substitution were unchanged, and a Tn5 mutant, derived from strain 248 and unable to induce nodules, synthesise small amounts of EPS that lacked galactose. Expand
Genetic analysis of a cluster of genes required for synthesis of the calcofluor-binding exopolysaccharide of Rhizobium meliloti
TLDR
Rhizobium meliloti produces an acidic, Calcofluor-binding exopolysaccharide which plays a role in nodulation of alfalfa plants by this bacterium and 102 transposon insertions in a 48-kilobase region previously shown to contain several exo genes are constructed and mapped. Expand
Two genes that regulate exopolysaccharide production in Rhizobium sp. strain NGR234: DNA sequences and resultant phenotypes
Two closely linked genes involved in the regulation of exopolysaccharide (EPS) production in Rhizobium sp. strain NGR234, exoX and exoY, were sequenced, and their corresponding phenotypes wereExpand
The exoR gene of Rhizobium meliloti affects RNA levels of other exo genes but lacks homology to known transcriptional regulators
TLDR
It is shown that an exoR strain contains higher levels of mRNA for other exo genes than does the wild-type parental strain, and that ExoR most probably exerts its regulatory effect at the level of transcription. Expand
