Chlorophyll derivatives enhance invertebrate red-light and ultraviolet phototaxis

Abstract Chlorophyll derivatives are known to enhance vision in vertebrates. They are thought to bind visual pigments (i.e., opsins apoproteins bound to retinal chromophores) directly within the retina. Consistent with previous findings in vertebrates, here we show that chlorin e6 — a chlorophyll de...
