Expression dynamics of skin-enriched genes. Using RNA-Seq expression profiles, the 31,901 Ensembl release 92 zebrafish genes were classified (see File S1) at 20 SS into categories of ‘S’kin genes vs. ‘N’onskin genes, and at each of 52 and 72 hpf into categories of ‘P’eriderm-preferred genes, ‘B’asal-preferred genes, ‘G’eneral skin genes, and ‘N’onskin genes. Each gene thus belongs to exactly one of 32 possible “flows”, of which 28 have at least one gene (all of which except NNN are depicted, with width proportional to the number of genes). 15 flows have at least 70 genes, and 10 flows have at least 200 genes.
