To investigate whether MoKat2 plays a role in the regulation of peroxisome dynamics in response to host-derived ROS during infection, we examined the peroxisome morphology in IH of Guy11, ∆Mokat2, and MoKAT2-C expressing Pex14-GFP at 24, 48, and 72 hpi with or without DPI treatment, respectively. Here, PEX14 is linked to infection.
