The Rhizobium Ieguminosarum biovar viciae nod0 gene can enable a nod€ mutant of Rhizobium leguminosarum biovar trifolii to nodulate vetch
Sciences, University of East Anglia, Norwich NR4 7TJ, UK 2 School of Biological Analysis of the nodulation characteristics of transposon-induced mutants of Rhizobium leguminosarum bv. viciae revealed that nodO and the closely-linked rhi genes contribute t o nodulation of peas (Pisum sativum) and the vetch Vicia hirsuta. Although mutation of nodO alone had no significant effect on nodulation of ...
متن کاملIdentification of a NodD repressible gene adjacent to nodM in Rhizobium leguminosarum biovar viciae.
The nodFEL and nodMNT operons in Rhizobium leguminosarum biovar viciae are transcribed in the same orientation and induced by NodD in response to flavonoids secreted by legumes. In the narrow intergenic region between nodFEL and nodMNT, we identified a small gene divergently transcribed from nodM to the 3' end of nodL. Unlike the promoters upstream of nodF and nodM, the promoter of this gene is...
متن کاملGene amplification in Rhizobium: identification and in vivo cloning of discrete amplifiable DNA regions (amplicons) from Rhizobium leguminosarum biovar phaseoli.
A genetic element that allows the positive selection of different genomic rearrangements was used to analyze DNA amplification in Rhizobium leguminosarum biovar phaseoli. Discrete amplifiable DNA regions (amplicons) were detected in different regions of the genome of the model strain CFN42, including the chromosome and several large plasmids. Amplicons were mobilized into Escherichia coli using...
متن کاملRhizoplane colonisation of peas by Rhizobium leguminosarum bv. viceae and a deleterious Pseudomonas putida.
Pseudomonas putida strain A313, a deleterious rhizosphere bacterium, reduced pea nitrogen content when inoculated alone or in combination with Rhizobium leguminosarum bv. viceae on plants in the presence of soil under greenhouse conditions. When plants were grown gnotobiotically in liquid media, mixed inocula of A313 and rhizobia gave a higher proportion of small evenly distributed nodules when...
متن کاملChemotaxis of Rhizobium leguminosarum biovar phaseoli towards Flavonoid Inducers of the Symbiotic Nodulation Genes
Chemotaxis of Rhizobium leguminosarum biovar phaseoli RP8002 towards a range of carbohydrates, phenolic compounds and flavonoids was assayed. Xylose (peak response M) were strong chemoattractants amongst the carbohydrates, whilst glucose, fructose, galactose and maltose produced little or no detectable response. Of the monocyclic phenolic compounds, vanillyl alcohol, p-hydroxybenzoic acid (both...
