Three BcHsbA genes (<i>BcHsbA1</i>, <i>BcHsbA2</i>, and <i>BcHsbA3</i>) are dispensable for osmotic, cell wall, and oxidative stress adaptation.

(A) Sensitivity test of different strains to the osmotic stress (NaCl and KCl), cell wall stress (CR), and oxidative stress (H2O2). Strains were incubated on PDA plates supplemented with 1 mol/L NaCl, 1 mol/L KCl, 300 μg/mL CR, or 5 mmol/L H2O2 at 20°C for 3 days. (B) The relative mycelial growth rate of different strains. Means ± standard errors labeled with the same letter are not significantly different (P > 0.05) according to the least significant difference test. (TIF)
