Impact of brlA or abaA disruption on radial growth and stress response of M. robertsii. (A,B) Images and diameters of fungal colonies grown at the optimal regime of 25 °C and L:D 12:12 for 7 days on nutrition-rich (PDA, SDAY, and 1/4 SDAY) and minimal (CDA) media. (C,D) Diameters of 7-day-old fungal colonies grown at the optimal regime on CDA amended with different amino acids as nitrogen sources. (E) Relative growth inhibition (RGI) percentages of fungal colonies grown at 25 °C for 7 days on CDA plates supplemented with H2O2 (2 mM), menadione (MND, 0.03 mM), calcofluor white (CFW, 15 μg/mL), and Congo red (CGR, 1 mg/mL) respectively. All colonies were initiated with hyphal mass discs (ϕ = 5 mm) attached to plates. p < 0.05 * or 0.001 *** in Tukey’s HSD tests (ns, no significance). Error bars: SDs from three independent replicates.
