Activation of the σE-dependent stress pathway by conjugative TraR may anticipate conjugational stress.

abstract：:Two replicons were isolated independently from different IncHI1 plasmids. One was isolated from R27, and a second was isolated from pIP522. We demonstrate, by DNA-DNA hybridization experiments, that these maintenance regions are different and that they are specific to, and carried by, all IncHI1 plasmids tested. In vi...
