Deletion formation between the two Salmonella typhimurium flagellin genes encoded on the mini F plasmid: Escherichia coli ssb alleles enhance deletion rates and change hot-spot preference for deletion endpoints.

Abstract excerpt

Deletion formation between the 5'-mostly homologous sequences and between the 3'-homeologous sequences of the two Salmonella typhimurium flagellin genes was examined using plasmid-based deletion-detection systems in various Escherichia coli genetic backgrounds. Deletions in plasmid pLC103 occur between the 5' sequences, but not between the 3' sequences, in both RecA-independent and RecA-dependent ways. Because...
