The gene <i>ivory:mir-193</i> controls scale type differentiation in <i>Heliconius</i> butterflies

2026-02-26

Abstract excerpt

The ivory:mir-193 locus is a genetic hotspot underlying melanic wing pattern variation across Lepidoptera, acting as a master regulator of melanic scale fate. This includes the genus Heliconius , where aposematic mimicry is driven by three scale cell types: light Type I, dark-melanic Type II, and red Type III scales. We tested functions of ivory:mir-193 in Heliconius using CRISPR-induced somatic mosaic knockou...
