A Kyoto Encyclopedia of Genes and Genomes analysis showed that the DEGs involved in the mitogen-activated protein kinase signaling pathway, autophagy–yeast, lysine biosynthesis, phenylalanine metabolism, and tryptophan metabolism responded to infection, and the expression patterns of key regulatory genes, including STE, ATG, CYP, and LYS differed after infection indica and japonica rice. Here, PPIG is linked to infection.
