Nodulation genes from Rhizobium leguminosarum have been subcloned and transferred to a strain of R. phaseoli with its symbiotic plasmid deleted (and therefore its nodulation and nitrogen fixation genes). Normal infection and nodule development occurred when these strains were added to the roots of Pisum sativum (peas) and Vicia hirsuta. The pea nodules were examined by electron microscopy; bact...

Rhizobium leguminosarum bv. viciae RCAM1026 is a strain first isolated in 1964 from nodules of "Ramensky 77" cultivar of garden pea (Pisum sativum L.) now routinely used as a model strain in inoculation experiments on pea. Assembly with SPAdes yielded 133 contigs longer then 200 bp (N50 = 202,321, GC% = 60.84). Resulting annotated genome is 7,248,686 bp encoding 6792 genes.

abstractin order to investigate the effects of the inoculation with p. putida, r. leguminosarum bv. phaseoli and f. mosseae on yield and nutrient uptake of common bean (phaseolus vulgaris l.), a greenhouse experiment in a completely randomized factorial design with 3 treatment including a: microorganism in four level (no inoculation, p. putida, f. mosseae and mix inoculation of fungi and bacter...

Rhizobium leguminosarum has two high-affinity Mn2+ transport systems encoded by sitABCD and mntH. In symbiosis, sitABCD and mntH were expressed throughout nodules and also strongly induced in Mn2+ -limited cultures of free-living cells. Growth of a sitA mntH double mutant was severely reduced under Mn2+ limitation and sitA and mntH single mutants were more sensitive to oxidative stress. The dou...

This study was conducted in the Department of Nematology, College Agriculture, OUAT. The experiment designed using completely randomized design (CRD) with different combinations root knot nematode (Meloidogyne incognita) and leguminosarum strain rhizobium three field pea germplasms, which are resistant, moderately resistant susceptible against infection. Different combination interaction betwee...
