Fig 1. Genetic determinants of Xer recombination at dif.

Fig 1

(A) Scheme of the dif-cassette excision genetic assay. (B) Influence of homologous recombination on the rate of dif-cassette excision in E. coli and V. cholerae cells grown in LB for 16 h and 3 h, respectively. Mean of 5 independent experiments. Ec: E. coli; Vc: V. cholerae; **: p<0.001 (t-test with a Two-tailed distribution). (C) recA-dependency of dif-cassette excision in E. coli and V. cholerae cells harbouring hybrid dimer resolution machineries. Mean of at least 3 independent experiments. Ec: E. coli cells grown for 16 h in LB; Vc: V. cholerae cells grown for 3 h in LB; recA-dependency: fraction of the dif-cassette excision rate that is linked to recA, 1-frecA-/frecA+.
