Abstract The color pattern of insects is one the most diverse adaptive evolutionary phenotypes. However, molecular regulation this not fully understood. In study, we found that transcription factor Bm-mamo responsible for black dilute ( bd ) allele mutations in silkworm. belongs to BTB zinc finger family and orthologous mamo Drosophila melanogaster . This gene has a conserved function gamete production silkworms evolved pleiotropic patterns caterpillars. Using RNAi clustered regularly interspaced short palindromic repeats (CRISPR) technology, showed repressor or dark melanin larval epidermis. vitro binding assays expression profiling wild-type mutant larvae, also likely regulates related pigment synthesis cuticular protein genes coordinated manner mediate its role formation. mechanism consistent with dual regulating both structure shape cuticle pigments are embedded within it. study provides new insight into as well construction more complex epidermis features some insects.

The study of color patterns in the animal integument is a fundamental question biology, with many lepidopteran species being exemplary models this endeavor due to their relative simplicity and elegance. While significant advances have been made unravelling cellular molecular basis pigmentary coloration, morphogenesis wing scale nanostructures involved structural production not well understood. Contemporary research topic largely focuses on few nymphalid model taxa ( e.g. , Bicyclus Heliconius ), despite an overwhelming diversity hierarchical nanostructural organization scales. Here, we present time-resolved, comparative developmental Parides eurimedes five other papilionid species. Our results uphold putative conserved role F-actin bundles acting as spacers between developing ridges, previously documented several Interestingly, while ridges are P. plasma membrane manifests irregular mesh-like crossribs characteristic Papilionidae, which delineate accretion cuticle into rows planar disks ridges. Once grown, disintegrating appear reorganize network that supports invagination underlying disks, subsequently forming extruded honeycomb lattice. uncover undocumented for complex nanostructures, likely specific Papilionidae.
