Nitrate and nitrite reductases in the crude extract of aerobically grown Rhizobiwn meliloti were determined with methylviologen as electron donor at pH 7. Nitrate reductase was detected in the cells grown in the medium that did not contain nitrate, and in the presence of nitrate the specific activit
Using nitrosoguanidine (NTG) two nodulation defective (Nod-), auxotrophic mutants of the Rhizobium meliloti strain L5.30 have been isolated. In their Sym plasmid, pRmeLS.3Ob, a large deletion has been de- monstrated. Both mutants were adsorbed into root hairs of lucerne, but were unable to induce ro
