Transcriptome changes following thermal adaptation. Scatterplots of the average log2 relative intensity ratio for the 306 'differentially expressed genes' detected from the linear contrasts between the two furthest apart thermal selection regimes (i.e., 13°C vs. 22°C) and sorted according to the difference between warm- and cold-adapted (i.e., P22 – P13) populations. The sorted CG names of genes are given at the bottom (1, 3, 5, ⋯) and top (2, 4, 6, ⋯) axes. For each gene, the points in blue (P13), green (P18) and red (P22) give the average log2 relative intensity ratio for the different thermal regimes. The corresponding points have been connected by polynomial fitting to enhance visibility.
