Expression of selected genes involved in photoreceptor cell development in 7dpf larva. Column 1, 2 single labeling of gene X. Column 3–5 double labeling of gene X (cyan) and Las-r-opsin (magenta) in the anterior, posttrochal eye and posterior region. a1a5 Expression of Las-six1/2 in all PRCs as well as in the longitudinal nerve cords (a1). b1b5 Expression of Las-eya in all PRCs. c1c5 Expression of Las-dachshund in all PRCs, as well as a faint expression in the apical area (c1). d1d5 Las-pax6 is broadly expressed in the nervous system (d1), otherwise limited to the apical PRCs of young larvae (24–48 hpf) (d2, d3), not coexpressed with the Las-r-opsin in the eye PRCs, but in adjacent, more distal cell bodies (d4), no expression in the posterior PRCs (d5). e1e5 Expression of Las-ovo in all PRCs. f1f5 Expression of Las-lhx2/9 in all PRCS, as well as a broader expression in the entire nervous system (f1). (Scalebars 100 μm in column 1; 50 μm in column 2; 5 μm in columns 35)
