Abstract excerpt
The rhizobial production of extracellular polysaccharide (EPS) is generally required for the symbiotic infection of host plants that form nodules with an apical meristem (indeterminate nodules). One exception is Rhizobium meliloti AK631, an exoB mutant of Rm41, which is deficient in EPS production yet infects and fixes nitrogen (i.e., is Fix+) on alfalfa, an indeterminate nodule-forming plant. A mutation of lpsZ...
