Expression of photoreceptor regulatory state and PSED genes in sea urchin larvae. A WMISH in 72-h larvae showing the expression of selected regulatory genes in ciliary photoreceptors (arrowheads). Additional regulatory genes expressed in photoreceptors are shown in Fig. 4. B WMISH in 72-h larvae showing the expression of pax6, six1/2, dach, and eya in the hydropore canal (HC).
