Fig. 7. Schematic representation of the spatiotemporal expression patterns of RH2
opsin subtypes in zebrafish retina (lateral views) reconstructed from ISH to
serial sections. Expression areas of RH2-1, RH2-2 and RH2-3
are indicated with different shades of gray (light, middle and dark,
respectively). That of RH2-4 is indicated with black. Dots in
RH2-2 expression at two weeks pf indicates sparse expression in the
central retina. Up to 1 month pf, expression of RH2-3 and
RH2-4 was not distinguishable. D, dorsal; V, ventral; N, nasal; T,
temporal.
