Abstract:The success of butterflies and moths is tightly linked to the origin of scales within the group. A long-standing hypothesis postulates that scales are homologous to the well-described mechanosensory bristles found in the fruit flyDrosophila melanogaster, where both derive from an epithelial precursor specified by lateral inhibition that then undergoes multiple rounds of division. Previous histological examination and candidate gene approaches identified parallels in genes involved in scale and bristle developm… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
