To identify the fungal enzyme responsible for neutralizing ROS at the infection front, we reanalysed F. graminearum genome‐encoded catalase and catalase‐peroxidase genes (Table S1) based on phylogenetic analysis, conserved protein domains and subcellular localization prediction (Emanuelsson et al., 2000; Goldberg et al., 2014; Horton et al., 2007; Nielsen et al., 1997). Here, CAT is linked to infection.
