ODs after irradiation. Exposure to increasing UV dose is reflected in a gradual reduction of growth. This reduction in cells carrying the autogenous circuit (A) is smaller than that observed in cells bearing the nonautogenous one (B) for an equivalent damage situation. Thus, the overresponse induced by the nonautogenous control comes at a cost. (Insets) Growth rate (ν) vs. time for intermediate and high UV doses relative to a nonradiated situation (same color code as main images).
