PEX3 and infection: Besides the five above-mentioned proteins’ genes, three genes, namely, VAMP (LOC_Os10g06540) on the SNARE interactions in vesicular transport pathway, AT (LOC_Os05g15530) on the folate biosynthesis pathway and PEX3 (LOC_Os09g14510) on the peroxisome pathway, were also selected to analyze their transcriptional abundance in the roots of rice before and after infection of M. graminicola.
