RESUMO
Two Escherichia coli K-12 Hfr strains have been constructed which transfer a recA deletion, which is highly linked to a Tn10 insertion conferring tetracycline resistance, early during conjugation. These strains transfer the recA deletion in opposite directions with different origins of transfer, allowing for preservation of desirable recipient strain markers either clockwise or counterclockwise of recA.
