Scientists use CRISPR to tweak butterfly wing color, change wing scale surface structure
Pigments and the fine structure of butterfly wing scales work together to generate a mosaic of colors and patterns that help the insect camouflage or attract mates. In the journal Cell Reports, scientists show it only takes a few pigment genes to modify both color and morphology of wing scales. Researchers used CRISPR/Cas9 to tweak wing colors of an East African butterfly and found that it changed the scales' surface structure, as well as color.
