Lineage-specific ohnologs (LSOs) retained by subfunctionalization or neofunctionalization.

<p>Gene duplicates showing signs of subfunctionalization and neofunctionalization as the main molecular mechanisms of retention. LSOs and singletons expression of <b>(A)</b> <i>transforming growth factor 3</i> (<i>tgfb3</i>), <b>(B)</b> <i>insulin like growth factor binding protein 3</i> (<i>igfbp3</i>), <b>(C)</b> <i>tripartite motif containing 63</i> (<i>trim63</i>), <b>(D)</b> <i>insulin like growth factor 2</i> (<i>igf2</i>), <b>(E)</b> <i>rptor independent companion of mtor complex 2</i> (<i>rictor</i>), <b>(F)</b> <i>follistatin</i> (<i>fst</i>), <b>(G)</b> <i>transforming growth factor beta 1</i> (<i>tgfb1</i>), <b>(H)</b> <i>growth factor receptor bound protein 2</i> (<i>grb2</i>), <b>(I)</b> <i>raf-1 proto-oncogene</i>, <i>serine/threonine kinase</i> (<i>raf1</i>), <b>(J)</b> <i>activating transcription factor 4</i> (<i>atf4</i>), <b>(K)</b> <i>akt serine/threonine kinase 2</i> (<i>akt2</i>), <b>(L)</b> <i>ras related GTP binding c</i> (<i>rragc</i>), <b>(M)</b> <i>component of inhibitor of nuclear factor kappa B kinase complex</i> (<i>chuk</i>) in pacu (green lines) and tilapia (red lines) skeletal muscle are represented as relative values, Mean±SE (n = 6).</p>
