Photomontage that highlights gene specialisations of the zebrafish ventral retina.

<p>These photomicrographs show radial sections of adult zebrafish retinae. They demonstrate specific expression of <i>rh2–4</i> (<b>A</b>), <i>lws-1</i> (<b>B</b>) and <i>gngt2a</i> (<b>C</b>) in the ventral retina (arrowheads), while <i>gnb3b</i> (<b>D</b>) shows expression in the dorsal and medial retina (black arrow). Note that <i>gnb3b</i> expression is absent in the ventral retina (asterisk). The pictures in panels <b>A</b> and <b>B</b> are used with permission from Takechi and Kawamura (2005) [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0121330#pone.0121330.ref051" target="_blank">51</a>] and Tsujimura <i>et al</i>. (2010) [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0121330#pone.0121330.ref050" target="_blank">50</a>], respectively. The pictures in panels <b>C</b> and <b>D</b> are extracted from the present results. Scale bars: 200 μm.
