CAT and infection: These ROS scavenging enzymes showed unique temporal regulation over the course of infection, with the peroxiredoxin and two of the peroxidases (Sscle03g024750 and Sscle01g000730) being most upregulated at 24 hpi but all four of the catalases and the remaining two peroxidases demonstrating greatest expression at 96 hpi (Additional file 14: Table S13).
