Figure 4From: Adaptive regulatory substitutions affect multiple stages in the life cycle of the bacteriophage ϕX174Mutants do not differ from Ancestor in ejection at A) 37°C or B) 42°C. Percent of starting phages that have not ejected (y-axis) vs time since the initiation of ejection. Phages were pre-attached to cells at 15°C and ejection was initiated by transferring pre-attached phages to the incubation temperature. Error bars indicate ± 1 SE.Back to article page
