Scheme of phenylpropanoid biosynthesis pathway and the expression level of DEGs in seedlings with pathogen infection (PaHp), endophyte inoculation (PaPs) and coinfection (PaPsHp) relative to non-inoculated seedlings control. The expression level was measure by log2(fold change). Fold change is the average ratio of FPKM of genes of infected seedlings (PaPs, PaHp, PaPsHp) to FPKM of genes of non-inoculated seedlings control. FDR adjusted P-values <0.05 are labeled with an asterisk.
