When the 225 kilobase (kb) cryptic plasmid of Rhizobium meliloti 41 is introduced into Agrobacterium tumefaciens C58, the resident plasmid pAtC58 (410 kb) is lost, probably because of incompatibility. The strain of A. tumefaciens cured of pAtC58 is still oncogenic, showing that pAtC58 does not control functions essential for tumour formation in the tomato and in Kalanchoe daigremontiana.
