Figure 6From: Adaptive regulatory substitutions affect multiple stages in the life cycle of the bacteriophage ϕX174Mutants do not differ from Ancestor in latent period but differ significantly in burst size at both temperatures. Mutants have lower burst size at A) 37°C and greater burst size at B) 42°C. Number of extracellular phages (y-axis) vs. time since the initiation of ejection (x-axis). Error bars indicate ± 1 SE.Back to article page
