Fig. 2From: Expression pattern of heat shock proteins during acute thermal stress in the Antarctic sea urchin, Sterechinus neumayeri Variation of gene expression during acute thermal stress in coelomocytes of S. neumayeri. Antarctic sea urchins were exposed to 3 °C and 5 °C for 1, 24 and 48 h. Grey bars: control group; white bars: 3 °C and black bars: 5 °C. Bars represent the mean of four individuals and error bars are standard error. *p < 0.05Back to article page
