A novel salmonid myoD gene is distinctly regulated during development and probably arose by duplication after the genome tetraploidization
چکیده انگلیسی

A novel myoD paralogue was characterised in Salmo salar (smyoD1c) and S. trutta (btmyoD1c). SmyoD1c had 78.2/90.6% protein sequence identity to smyoD1a/smyoD1b, respectively. Each paralogue was differentially expressed throughout somitogenesis. In adult fish, smyoD1a was the predominant gene expressed in fast muscle, whereas smyoD1c was 2–3 times upregulated in slow muscle compared to smyoD1a/1b. A maximum likelihood analysis indicated that myoD1c arose by duplication of myoD1b after the salmonid tetraploidization. Another myoD paralogue (myoD2) is present in at least some teleosts, reflecting a more ancient genome duplication. To accommodate these findings we propose a simplified teleost-myoD nomenclature.
