A strain of R. phaseoIi cured of its symbiotic plasmid, pRP2JI, retained the ability to make exopolysaccharide (EPS). However, a region of pRP2JI, when cloned at an increased copy number in wide host-range vectors and transferred to this and other strains of Rhizobium, inhibited EPS synthesis. The g

A gene termed psi (polysaccharide inhibition), located close to the nodulation genes of the Rhizobium phaseoli symbiotic plasmid pRP2JI inhibited exopolysaccharide synthesis (EPS) and nodulation ability (Nod) in Rhizobium when it was cloned in a multicopy plasmid. The sequence of psi showed that it
