Effects of cell wall and plasma-membrane stress on Δhex1. (A) Responses of the wild-type, the deletion (Δhex1), and the complemented (hex1-c) strains to calcofluor white M2R, Congo red, SDS, farnesol, and amphotericin B with regard to germination (top; the number of inoculated conidia per spot are provided above the images; growth for 3 days) and radial growth (right; growth for 18 days). CM: CzD-CM. (B) Relative growth inhibition by the same substances (each condition was tested in triplicate; bars = SD; statistical testing by one-way ANOVA followed by Tukey’s post hoc test (* p ≤ 0.05, ** p ≤ 0.01, *** p ≤ 0.001). All concentrations are given in μg/mL.
