A Rhizobium meliloti mutant that forms ineffective pseudonodules in alfalfa produces exopolysaccharide but fails to form β-(1→2) glucan
A mutant of Rhizobium meliloti that elicited the formation of inactive nodules in alfalfa was found not to form β-(1→2) glucan in vivo or in vitro. It was nonmotile because it lacks flagella. The 235-kilodalton protein which acts as an intermediate in β-(1→2) glucan synthesis was undetectable in the...
