Rhizobium leguminosarum symbiovar trifolii strains TA1 and CC275e are nitrogen-fixing microsymbionts of Trifolium spp. have been used as commercial inoculant for clovers in pastoral agriculture Australia New Zealand. Here we present the complete genome sequences both strains, resolving their multipartite structures allowing future studies using genomic approaches. [Formula: see text] Copyright ...

Several rhizobial strains were isolated from Phaseolus coccineus root nodules and were determined to be Rhizobium leguminosarum biovar phaseoli strains after reinfection of the same host plant. These strains were characterized by cultural procedures (growth on different carbon sources and intrinsic antibiotic resistance) and electrophoretic procedures (sodium dodecyl sulfate-polyacrylamide gel ...

According to Statistics Canada, the cropping area for field pea (Pisum sativa) in Western Canada has increased from 25 000 ha in 1976 to 1 335 000 ha in 2001. As part of the production system, field peas require inoculation with Rhizobium leguminosarum bv. Viceae, particularly, when grown for the first time in rotation. Appropriate rhizobial inoculation and fertility management can increase fie...

A limited number of strains belonging to several genera of Rhizobiaceae are capable of expressing a hydrogenase system that allows partial or full recycling of hydrogen evolved by nitrogenase, thus increasing the energy efficiency of the nitrogen fixation process. This review is focused on the genetics and biotechnology of the hydrogenase system from Rhizobium leguminosarum bv. viciae, a freque...

evaluation of genetic diversity is a considerable approach to screen within indigenous rhizobial population for compatible, highly effective strains, which can be further utilized as rhizobial inoculums. genetic diversity of rhizobium isolates from three clover species grown in soil samples of seven different geographical regions in iran was investigated by repetitive extra genomic palindromic ...
