SOD1 and infection: Several genes associated with oxidoreductase and antioxidant activity were also down-regulated in isolate-17N, including the catalase CAT2 (FGRAMPH1_01G11527), involved in ROS scavenging, and the super-oxide dismutase (SOD) gene SOD4 (FGRAMPH1_01G23885) [55], where SODs play a role in surviving high ROS concentrations generated by oxidative burst of host cells in response to infection [53].
