Figure 5. Digital gene expression in two tissues with the following labels: G – Gill, H – Hepatopancreas, M – Healthy Muscle.

Each point represents a unigene. The x and y-axis are the log₁₀ of the normalized expression level (RPKM) of unigene in the indicated tissue. Red and green points indicate significant change at the absolute value of log₂ (RPKM ratio in two tissues) ≥1 and FDR  = 0.001. Red points indicate up-regulated unigenes and green points indicate down-regulated unigenes in the tissues in which its expression level is represented by the y-axis. Blue points indicate insignificant differentially expressed unigenes. (a) Expression level of unigenes in G versus H, (b) Expression level of unigenes in G versus M and (c) Expression level of unigenes in H versus M.
