Genotypic characterization of indigenous rhizobium strain from cultivated cowpea (Vigna unguiculata L.) in Bangladesh

A gram negative strain of Rhizobium sp. SOY7 has been isolated from root nodules of cow pea (Vigna unguiculata L.) which was later identified on the basis of biochemical tests and 16S rDNA sequencing. The optimum culture condition of Rhizobium sp. SOY7 was determined at pH 7.0 and 28˚C temperature
