Box plot representation of hyphal length (µm, y-axis) following incubation on solid MM at 30 °C for 18 h. Morphogene expression was titrated using the four described Dox concentrations. Asterisks indicate where hyphal length of mutant isolate significantly deviates from MA70.15 control at the respective Dox concentration (Students t-test *p < 0.05, **p < 0.01, ***p < 0.001). Approximately 30 hyphae per strain/Dox condition were quantified. Y-axis: hyphal length (µm)
