An approach originally designed to identify functional origins of conjugative transfer (oriT or mob) in a bacterial genome (J. A. Herrera-Cervera, J. M. Sanjuán-Pinilla, J. Olivares, and J. Sanjuán, J. Bacteriol. 180:4583-4590, 1998) was modified to improve its reliability and prevent selection of undesired false mob clones. By following this modified approach, we were able to identify two func...

Lac(+) revertants of Escherichia coli that occur after prolonged nonlethal selection display a high frequency of transposon loss when the transposon Tn10 and the reverting lacI33 allele are linked on an F'128 episome. As many as 20% of the Lac(+) revertants are sensitive to tetracycline, about half because of transposon loss, nearly all by precise excision, and the remainder because of amplific...
