The transient inability of the conjugating female cell to host 186 infection explains the absence of zygotic induction for 186.

RESUMO

In an Hfr(186) X F- cross, the 186 prophage on the incoming male chromosome is not induced, despite the fact that prophage 186 can be induced by other means (W. H. Woods and J.B. Egan, J Virol. 14:1349-1356, 1974). We show here that the conjugating female is temporarily inhibitory to infection by 186, and this delay, we postulate, enables cI repression to be reestablished before the female cell recovers its 186 sensitivity.
