Abstract
The analysis of heteroduplexes between EcoRI digested DNA derived from IncM plasmids in the transfer‐off and in the transfer‐on state revealed an internal loop of about 1 kbp on a distinct large EcoRI fragment. The presence of an invertible element (Min) is suggested which enables the formation of conjugative piliat 30 °C, but switches off the pilus formation at 37 °C incubation temperature.Keywords
