Ranks and numbers of day-night genes per tissue for the real day-night analysis and the median of 1,000 random permutations.

For each tissue, the number of day-night genes from the real data (GTEx, circle) or the median number of day-night genes over the 1,000 random permutations (permutation, diamond) was computed (y-axis). The tissues were ordered according their number of day-night genes (x-axis), independently for the GTEx and the permutation dataset. DEGs, differentially expressed genes. The data underlying this figure can be found in S1 Data. (PDF)
