Figure 3From: Interpopulation differences in expression of candidate genes for salinity tolerance in winter migrating anadromous brown trout (Salmo trutta L.)Expression of hsp70 in gill tissue of trout from River Ribe and River Grenaa following acclimation to freshwater (FW) and seawater (SW) at 2°C and 10°C. Amounts of hsp70 mRNA are normalized to the corresponding EF1α abundance from the same sample, and mean values are expressed in arbitrary units ± SE (number of individuals in experimental groups: n = 8). * indicates significant difference between salinity treatments (P < 0.05) and # indicates significant difference between temperature acclimation groups at the same salinity (P < 0.05).Back to article page
