Comparison of the gene expression profiles between Haliotis discus hannai (DD) and hybrid H. discus hannai ♀ × H. fulgens ♂ (DF) during short-term low salinity stress: A Calmodulin-4, B Heat shock protein90, C Tumor necrosis factor, D Bone morphogenetic protein-4, and E Nuclear factor kappa-B. Sampling times = “0 h”: control group; “3 h”, “12 h”, and “24 h”: exposure times at low salinity. Statistical analysis was performed by Welch’s t-test at a given sampling time. Differences were deemed significant at P < 0.05. “*”: P = 0.01; “**”: P = 0.004; “***”: P = 0.000
