Fig. 1. Example of a time course of mRNA expression of SSH clones in response to salinity stress (SSH#81, protein phsophatase-2A catalytic subunit, is shown). mRNA expression was analyzed at the indicated times after transfer of tilapia from freshwater to seawater (SW). Expression levels were quantified by qPCR in gill epithelial cells. Values are means ± s.e.m. (N=4).
