Outline of Final Research Achievements

Compound eyes of many insects consists of two spectrally-heterogeneous ommatidia. The number is three in butterflies and bees, making their eyes spectrally richer. Is this an adaptation for having better color vision in flower-visitors? We addressed this question by comparing the eye development in flies and butterflies. A transcription factor Prospero (Pros) is expressed in a short-wavelength receptor, R7, in all ommatidia in flies. We found Pros is expressed in two cells per an ommatidium in butterflies: R7 seems to be duplicated. Ommatidial heterogeneity is detected in flies by stochastic expression of Spineless (Ss) in R7. In butterflies, two R7-like cells express Ss in three patterns, on/off, on/on and off/off, as if they correspond to three ommatidial types. In fact, butterflies whose ss gene is knocked-out have only the UV-UV type ommatidia. It thus appears that the spectral richness of butterfly eyes is associated with duplication of R7-like cell in the process of adaptation.
