Antennapedia regulates metallic silver wing scale development and cell shape in Bicyclus anynana butterflies
Butterfly wing scale cells can develop very intricate cuticular nanostructures that interact with light to produce structural colors such as silver, but the genetic basis of such nanostructures is mostly unexplored. Here, we address the genetic basis of metallic silver scale development by leveraging existing crispants in the butterfly Bicyclus anynana , where knockouts of five genes — apterous A…
