*Available expression data on AtWRKY genes from microarray analysis and that of CsWRKY genes generated by real-time PCR analysis were used to calculate the Pearson correlation coefficient for the expression of orthologous WRKY genes under various abiotic stresses (after 0, 0.5, 1, 3, 6, 12, and 24 h treatment)(as showed in Figure 7)as described in the Methods.
**a randomly chosen abiotic stress induced cucumber WRKY gene and a randomly chosen abiotic stress induced AtWRKY gene composed of a random gene pair. This process was repeated a 100 times and produced 100 random WRKY gene pairs. The expression correlation of each of 100 random WRKY gene pair was calculated as described in the Methods
