Direction of conjugative transfer of IncI1 plasmid ColIb-P9.

AUTOR(ES)
RESUMO

The origin-of-transfer region of ColIb-P9 was inserted into a lambda prophage to give a bacterial chromosome mobilizable by the parental conjugative plasmid. The polarity of mobilization of chromosomal genes indicated that ColIb-P9 transfer is unidirectional, such that the transfer genes adjacent to oriT enter the recipient cell last.
