RecF, recQ, ruv, recJ and recN genes of so called RecF pathway of recombination appear to be not silent on the RecBCD pathway also. These genes are responsible for the frequency of recombination exchanges per unit length of DNA. The list: recF::Kmr greater than recQ::Tn3 greater than ruv54 greater than recJ::Tn9 demonstrated the efficiency of inhibition of recombination exchanges by these mutations. The recN262 mutation gives a feeble contrary effect. It slightly increases the frequency of recombination exchanges. |
