Many PEX genes (PEX3, PEX26, PEX11), which are essential for peroxisome’s maturation and growth [119], and peroxisomal enzymes involved in lipid metabolism (EPHX2, ACOT8) or antioxidant systems (GSTK1) were intensely down-regulated in the initial stages of the infection while the PEX genes PEX5la and PEX26 were upregulated 48 hpi. This evidence concerns the gene GSTK1 and infection.
