Matrix representing Pearson’s correlation coefficients between log2-transformed RQs of hepatic transcripts (rows) and phenotypic features such as omega-3 and omega-6 FAs levels in muscle and weight gains (columns) of the salmon fed the experimental diets. Significant differences among diets (one-way ANOVA, p < 0.05) are indicated on the right of the transcript abbreviations and below the phenotypic variables. Transcriptomic and phenotypic data were arranged based on a hierarchical clustering performed using Pearson correlation resemblance matrices (PRIMER, Version 6.1.15, Ivybridge, UK). Dendrograms next to transcript abbreviations and above phenotypic parameters represent the results of the hierarchical clustering analysis. PUFA: polyunsaturated fatty acid; SFA: saturated fatty acids; DHA: docosahexaenoic acid (22:6ω3); EPA: eicosapentaenoic acid (20:5ω3); WG: weight gain; ARA: arachidonic acid (20:4ω6)
