Abstract
R. trifolii strains containing plasmid pWZ2, the genetic element indispensable for nodule induction, showed a strong specific adsorption of cells to clover roots. Elimination of the plasmid pWZ2 from bacteria caused loss of adsorption capability, and this property could be recovered by introduction of the plasmid into bacterial cells. The results obtained indicate that the plasmid pWZ2 contains gene(s) controlling the 1st stage of Rhizobium-legume symbiosis which is a specific adsorption of nodule bacteria to a suitable plant host.
