Abstract
Some I-like R plasmids, R483, R144, R64drd-11 and R621a, belonging to compatibility groups IncI alpha and I gamma promoted degradation of stable RNA in the srnA1 cells of Escherichia coli after addition of rifampin at 42 degrees C. R16 and R834 plasmids of compatibility group IncB also promoted the degradation of RNA. However, other many kinds of plasmids did not. The promotion of RNA degradation was delayed by the addition of chloramphenicol with rifampin.
