Within the Agrobacterium vitis group the vitopine strains represent a special subclass. Vitopine bacteria carry Ti plasmids with little or no homology with the well-characterized T-DNAs of Agrobacterium tumefaciens or Agrobacterium rhizogenes. The 262-kb Ti plasmid of the vitopine strain S4 was cloned and mapped. Homology studies with the octopine Ti plasmid pTiAch5, the nopaline Ti plasmid pTiC58, and the agropine/mannopine Ri plasmid pRiHRI identified several regions of homology. The origin of replication was localized to within 2.5 kb.
