Figure 3From: Differential expression of the heat shock protein Hsp70 in natural populations of the tilapia, Sarotherodon melanotheron, acclimatised to a range of environmental salinitiesRelationship between mRNA expression levels of Hsp70 and Naka (Y = 0.994X + 2.204; R2 = 0.727; P < 0.001). The mRNA expression levels represent the relative expression normalized to β-actin and are expressed relative expression as log2-transformed data.Back to article page
