The expression pattern of tilapia gas2 in different tissues under low temperature stress was detected by the quantitative RT-PCR. The β-actin gene was used as an internal control to calibrate the cDNA template for all the samples. Data are expressed as the mean ± SD (n = 3). Significant differences are indicated with two asterisks at p < 0.01, and one asterisk at p < 0.05
