The entire genome of the pRi1724 (217.6-kb) in the mikimopine type Agrobacterium rhizogenes strain MAFF03-01724 has been completely sequenced. The vir region covering 30.2-kb has found to be composed of 21 genes resembling virH1, virA, virB1-11, virG, virC1-2, and virD1-5. The structural organization of the pRi1724 vir operons in this study is exactly the same as that of the previously reported vir operons of other Ri or Ti plasmids, although the size of some ORFs showed little variations among the plasmids. We also found virE3 gene in the pRi1724 (1), but different from Ti plasmids, virE1 and virE2 that are also important for the virulence do not exist in the vir region of pRi1724.
