Figure 4

Venn diagram of differentially expressed genes (DEGs) in different comparisons. The overlaps represent the number of intersections of unigenes shared by the control group (0 h) and the two experimental groups (3 h and 3 d). Gi, gill; HP, hepatopancreas; 0 h, control; 3 h, Cd²⁺ treated 3 h; 3d, Cd²⁺ treated 3 days.
