PCA biplots and MA plots showing gene expression patterns affected by diets. Three PCA biplots on the left show the first and second PCA components of top 500 high variance genes of RNA-seq counts with VST (variance stabilization transformation) for a gonads, b liver and c G&L (gonads and liver) datasets. The areas of three diet groups (L1: red, L2: green, L3: blue) and two tissue types (liver: turquoise, gonads: red) are outlined by convex hulls. d MA plots show the normalised read counts and log fold changes of all the mapped genes for gonads, liver and G&L datasets. Red dots indicate DEGs (adjusted p-value < 0.1), whereas grey dots indicate the genes with no significant differences
