Characterizing 5′ ends of fish Igf2 genes by analysis of RNA-Seq libraries. A–G, mapping putative 5′ ends of fish Igf2 genes by examination of gene expression data from species-specific RNA-Seq libraries, with 60-bp genomic segments a–e or a–f as probes. A, fugu, library SRX4020085 (liver). B, stickleback, library SRX2712198 (liver). C, cod, library SRX1044010 (liver). D, tilapia, library SRX1257756 (liver). E, platyfish, library SRX031881 (whole embryo). F, spotted gar, library SRX661023 (whole embryo). G, Medaka, library SRX661040 (liver).
