Selected target genes validated by RT-qPCR. Difference in fold change for gene expression in P. infestans between different treatments: in the presence of LBUM223, exogenically applied PCA or LBUM223phzC-. For each treatment, differences in gene expression were obtained by RNA-Seq (all times combined) and RT-qPCR. For RT-qPCR, the fold changes represent differential gene expressions observed between treatments and control. Shades of red are associated with up-regulation of gene expression, while shades of green were used for down-regulation of gene expression. Pearson’s correlations were calculated for each treatment between RNA-Seq and RT-qPCR results (p < 0.0001): R²_(LBUM223) = 0.935, R²_(PCA) = 0.887 and R²_{(LBUM223phzC-)} = 0.838
