The activities of enzymes involved in the antioxidant system in PoLaeA1-silenced strains. The P. ostreatus strains (WT, SiControl, LaeA1i-16 and LaeA1i-38) were cultured in liquid CYM at 28 °C for 5 days. The grounded mycelia were suspended in phosphate-buffered saline buffer. After centrifuging, the supernatants were used to detect the enzyme activities involved in ROS scavenging. (A) APX activity. (B) CAT activity. (C) GPX activity. (D) SOD activity. The values are the mean ± SD (n = 3). Different lowercase letters indicate significant differences between the strains (p < 0.05, according to Dunnett’s multiple comparisons test).
