FIG 9.

Silencing of AfPXG enhanced antioxidant activities. SOD and CAT activities were measured in the strainsin which AfPXG was silenced and the WT strain. SOD activity was assayed by measuring its ability to inhibit the photochemical reduction of nitroblue tetrazolium (NBT). CAT activity was measured by monitoring the decrease in absorbance due to H₂O₂ reduction at 240 nm for 2 min. Each point represents the result of triplicate measurements. Values are means ± SDs (n = 3). Asterisks indicate significant differences between the enzymatic activities of each line in which AfPXG was silenced and the control (*, P < 0.05; **, P < 0.01).
