Venn diagram. Graphs show the number of differentially expressed genes (DEGs) in Phytophthora sojae infecting soybean in comparison with P. sojae in axenic culture. Number of DEGs (Fold-change ≥4, FDR p-value ≤0.01) observed in Si⁻ plants (a), Si⁺ plants (b) at 4 (blue), 7 (yellow) and 14 (green) dpi. and (c) comparative number of DEGs in P. sojae between Si + (blue) and Si- (yellow) plants at 4, 7, 14 dpi. The number of unique DEGs was consistently higher in Si- plants than in Si + plants and the highest at 4 dpi. The up and down arrows indicate the number of up- and down- regulated genes, respectively, for each timepoint
