The number of differentially expressed genes (DEGs) identified in CK-VS-Y, CK-VS-Z and Z-VS-Y comparison. CK: control; Y: aphid infestation treatment; Z: mock puncture treatment. CK-VS-Y: comparison between CK and Y. CK-VS-Z: comparison between CK and Z. Z-VS-Y: comparison between Z and Y. The criteria used for assigning significance were: P-value < 0.05, FDR ≤ 0.001, and estimated absolute |log2Ratio(Y/CK)| ≥ 1. A: number of DEGs up- or down-regulated in CK-VS-Y, CK-VS-Z and Z-VS-Y comparison; B: number of DEGs specifically or co-expressed in CK-VS-Y, CK-VS-Z and Z-VS-Y comparison.
