Differentially expressed genes (DEGs) of each two libraries. Differentially expressed genes were identified by filtering of the two-fold up- and down-regulated genes with FDR ≤ 10-4. Comparison of sample A with B was designated as A > B, in which A was the treatment and B was the control. W: Wangshuibai; M: NAUH117. 0/24/48 represents hours after inoculation. The y-axis indicates the number of DEGs for each comparison.
