FIGURE 7: Comparison of intracellular pHi estimations in the transient response to salt and acetic acid stresses of hrk1Δ deletion mutant strains and the respective parental strains Range plots illustrating the estimated pHi values for each of the tested conditions – 30 minutes exposure to high salt (0.8 M KCl or 0.5 M NaCl) and acetic acid stress (30 mM at pH 4.0) – at each end of the range for the hrk1Δ deletion mutant strains (depicted in red), and the respective parental strains (depicted in blue).
