| Abstract | The polA^+ gene can be transducted in a multicopy mini-Mu plasmid, but not cloned because the product of this gene is lethal when overproduced. Although, we obtained one surviving cell, in which the ColEl-derived mini-Mu plasmid suffered a spontaneous deletion exactly at the region where the polA^+ gene was cloned. The PolA^+ unstream flanking sequence containing the promoter and pribnow-box was delected in vivo ; consequently this gene is not able to be expressed. | ||
