Effects of pssB Mutation on Surface Polysaccharides and Symbiotic Phenotype of Rhizobium leguminosarum bv. trifolii

摘要

The Rhizobium leguminosarum bv. trifolii pssB gene encodes a protein with inositol monophosphatase activity (I–1-Pase) which shares sequence similarity with a family of diverse prokaryotic and eukaryotic enzymes. A pssB::lacZ-Gmr mutant (Rt12A) that doe
