Digital gene expression between control group and
infected group. Each point represents a unigene. The x- and y-axis are the log10 of the normalized expression level (FPKM) of unigene between the two groups. Red and green points indicate significant change at the absolute value of log2 (FPKM ratio in two groups) ≥1 and fdr =0.001. Red points indicate up-regulated unigenes and green points indicate down-regulated unigenes in the two groups which its expression level is represented by the y-axis. Blue points indicate insignificant differentially expressed unigenes.
