Single-nucleus transcriptomics of wing sexual dimorphism and scale cell specialization in sulphur butterflies
Fig 4
Doublesex controls the specification of male-specific spatulate scales.
A. Magnified views of the dorsal hindwing marginal bands of mosaic Dsx G0 crispants. KO clone boundaries are visible with yellow/orange color shifts in the medial region, and in the marginal band, with shifts from canonical black scales to the spatulate scales in females, and vice-versa in males. B, C. Complete, reciprocal shifts in scale composition (B) and melanic scale identities (C) in both female and male Dsx crispants. Scale bars: A–C = 100 μm.
