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
The Rhizobiwn legutninosariint bv. trrfolii Sym plasmid pRtr5a was transferred by conjugation to R . nieliloti strains deleted or mutated in the nod and.fir genes, and also to a plasmid-less strain of Agrobacterium runie/ucieris. The plasmid transfer led to the elimination of the resident cryptic pl
