Abstract excerpt
exo mutants of Rhizobium meliloti SU47, which fail to secrete acidic extracellular polysaccharide (EPS), induce Fix- nodules on alfalfa. However, mutants of R. meliloti Rm41 carrying the same exo lesions induce normal Fix+ nodules. We show that such induction is due to a gene from strain Rm41, wh...
