Comparison of resistant genotype (S18) and susceptible genotype (P77) in response to V. dahliae inoculation. a Scatter plot of differentially expressed genes (DEGs) in the uninoculated resistant genotype (SCK) and susceptible genotype (PCK). b PCA3D figure, each dot represents a sample on the principal component value. c Hierarchical clustering of 2107 DEGs; the signal ratios are shown in a yellow-blue color, where yellow represents up-regulation and blue represents down-regulation. Each column (PCK, P6h, P12h, P24h, P2d, P3d, P5d, P10d and SCK, S6h, S12h, S24h, S2d, S3d, S5d, S10d) represents the RPKM value in each sample and each row represents DEGs. S and P: S18 and P77; CK: the genotype exempt from pathogen stress as control; 6 h, 12 h, 24 h, 2d, 3d, 5d, and 10d: resistant genotype (S18) and susceptible genotype (P77) infected with V. dahliae after 6, 12, 24 h and 3, 5, 10 days respectively
