Fig. 5From: The rhodopsin-retinochrome system for retinal re-isomerization predates the origin of cephalopod eyesExpression of retinal dehydrogenases in L. asellus in 7dpf larva. Column 1: single labeling of gene X. Column 2–4: double labeling of gene X (cyan) and Las-r-opsin (magenta) in the anterior, post trochal eye and posterior region. Las-RDH A (A1–A4), Las-RDH B (B1–B4), Las-RDH C (C1–C4) and Las-RDH D (D1-D4) are co-expressed with Las-r-opsin in anterior, eye and posterior PRCs. Scale bars: 100 μm in column 1; 5 μm in columns 2–4Back to article page
