Divergent SitA EDs dictate resistance profiles. (A) Competition indices of chimeras and parent sit(B)AI alleles where target cells were fluorescently labeled (top). The resistance profile of SitA5Mf1-AI3Mf1 (chimera C) was determined by its ED, while SitBA3Mx-AI5Mf1 (chimera A) was active against both resistant strains. (B) Competition indices as described above for panel A, except that the target strain was ΔsitI3MxsitBAI3Mx), to the test SitA5Mf1-AI3Mx (chimera D), where the SitA5Mf1 ED determines the resistance profile. SDs from three biological replicates are shown.
