“…Red deficiency results in a significant decrease in orange pterin in the wing of Colias butterflies. Research suggests that the product of red may interact with V-ATPase to modulate vacuolar pH across a variety of endosomal organelles, thereby affecting the maturation of pigment granules in cells ( Hanly et al, 2023 ). These findings indicate that the maturation of pigment granules plays an important role in the coloring of Lepidoptera and that Bm-mamo may be involved in regulating the maturation of pigment granules in the epidermal cells of silkworms.…”

Color pattern of insects is one of the most dazzling adaptive evolutionary phenotypes. However, the molecular regulation of this color pattern is not clear. In this paper, we found a transcription factor, Bm-mamo, is responsible for bd (black dilute) allele mutants in silkworm. It belongs to BTB zinc finger family, and is ortholog to mamo of Drosophila melanogaster, which It is found that this gene has conservative function in gamete production, and evolved a pleiotropic function in regulation of color patterns in caterpillar. We found that the Bm-mamo can comprehensively regulate the expression of related pigment synthesis and cuticular protein genes to form color patterns. This suggests that the deposition of pigment particles in caterpillars’ epidermis requires not only the spatiotemporal expression of pigment synthesis genes, but also the correct expression of related cuticular protein genes. This study provides a new data for the setting of color patterns.
