Fig 4. Stability of smaller oriC plasmids in M. bovis.

Fig 4

Schematic representation of genomic oriC region, IRR plasmids and predicted organisation of the oriC region following integration of different IRR plasmids. Southern blot analysis of EcoRI-PstI digested DNA probed with DIG-labelled probes targeting ampR (panel A) and oriC region (panel B). Smaller oriC plasmids were stable in M. bovis till p15-p20, but some integration appeared to have occurred in the oriC region. Lane 1, untransformed M. bovis; lanes, 2, 6 and 8, pIRR5632, pIRRPG2 and pIRR45, respectively. Lanes 3–5: pIRR5632 M. bovis transformants at p10, p15 and p20; lane 7, pIRRPG2 M. bovis transformants at p15; lanes 9–11, pIRR45 M. bovis transformants at p10, p15 and p20.
