Figure 7. Relative expression levels of Dauer formation protein-16-related genes. The diamond indicated the combined effect size of DAF-16-related genes, which did not intersect with the red-dotted-line, indicating hormesis could obviously increase (on the right) or decrease (on the left) the expression of these genes (p < 0.05). Abbreviation: daf-16, dauer formation protein-16; sod-3, superoxide dismutase-3; ctl-1, catalase-1; hsp-16.2, small heat shock protein-16.2.
