説明
<jats:title>Significance</jats:title> <jats:p>Human color vision is tri-chromatic, with three opsins expressed in cone photoreceptors that are sensitive in the red, green, and blue region of the spectrum. As theories predict, such tri- or tetra-chromacy with three or four opsin genes is common among mammals, birds, and other animals, including insects. However, we discovered that dragonflies possess as many as 15–33 opsin genes that have evolved through dynamic gene multiplications and losses within the lineage of dragonflies. These opsin genes are differentially expressed between adult and larva, as well as between dorsal and ventral regions of adult compound eyes, which plausibly underpin the versatile behavioral and ecological adaptations of actively flying adults to aerial lifestyle and sedentary larvae to aquatic lifestyle.</jats:p>
