Fig 1: Changes in the expression levels of the (A) SOD protein and (B) SOD mRNA in the digestive diverticula, and (C) SOD activity in the hemolymph of A. irradians during a 72 h period after sudden salinity change. Different characters indicate values corresponding to different exposure times of the scallops within the same salinity concentration (p < 0.05). Numbers indicate significant differences among salinity concentrations for the same exposure time (p < 0.05). All values are presented as the mean ± SD (n = 5). Abbreviations: SOD, superoxide dismutase and SD, standard deviation.
