Fig. 9

Graphic represents the effects of heat stress on the osmotic function of gill tissue in cold-water fishes. Orange box indicates heat stress-induced lower osmotic pressure in gill tissue, blue box means the osmotic regulation of gill tissue against the heat stress. The dots on left and right sides present the gene expression change in 24℃ vs 20℃ and 24℃ vs 20℃ groups, respectively. Red, blue and orange dots suggest significant upregulation (p < 0.05), downregulation (p < 0.05), and change without significant difference (p > 0.05), respectively
