ECR Spotlight is a series of interviews with early-career authors from selection papers published in Journal Experimental Biology and aims to promote not only the diversity researchers (ECRs) working experimental biology during our centenary year but also huge variety animals physiological systems that are essential for ‘comparative’ approach. Rachel Thayer an author on ‘ A meta-analysis butterfly structural colors: their color range, distribution biological production’, JEB. conducted research described this article while PhD student Nipam Patel's lab at University California Berkeley/Marine Biological Laboratory, USA. She now Postdoctoral Fellow David Begun California, Davis, USA, investigating genetic basis complex, adaptive traits, evolutionary innovation relationship between microevolutionary macroevolutionary processes diversity.

The success of butterflies and moths is tightly linked to the origin scales within group. A long-standing hypothesis postulates that are homologous well-described mechanosensory bristles found in fruit fly Drosophila melanogaster, as both derive from an epithelial precursor. Previous histological candidate gene approaches identified parallels genes involved scale bristle development. Here, we provide developmental transcriptomic evidence differentiation lepidopteran derives sensory organ precursor (SOP). Live imaging pupae shows SOP cells undergo two asymmetric divisions first abrogate neurogenic lineage, then lead a differentiated its associated socket cell. Single-nucleus RNA sequencing using early pupal wings revealed differential expression patterns mirror development, suggesting shared program. Additionally, recovered newly gene, transcription factor pdm3, proper butterfly wing scales. Altogether, these data open up avenues for understanding type specification illustrate how single-cell transcriptomics powerful platform evolution cell types.

Previous studies have shown that Optix regulates lower lamina thickness and the type of pigment is produced in wing scales a few butterfly species. However, role regulating production across species, additional aspects scale morphology remains to be investigated. By combining microspectrophotometry, scanning electron microscopy, focused ion beam technology on wild-type Bicyclus anynana crispants, we show orange pigments (ommochromes), represses brown (melanins), upper surface scales. Our findings suggest conserved as switch gene activates ommochrome melanin synthesis butterflies. comparing these effects with other mutations, where only removed from scales, propose pigmentary changes, alone, affect way chitin polymerizes within scale, changing well multiple intricate structures surface.

Biophotonic nanostructures in butterfly wing scales remain fascinating examples of biological functional materials, with intriguing open questions regard to formation and evolutionary function. One particularly interesting species, Erora opisena (Lycaenidae: Theclinae), develops that contain three-dimensional photonic crystals closely resemble a single gyroid geometry. Unlike most other gyroid-forming butterflies, E. discrete crystallites pronounced size gradient hinting at developmental sequence frozen time. Here, we present novel application hyperspectral (wavelength-resolved) microscopy technique investigate the ultrastructural organization these dry, adult scales. We show reflectance corresponds crystallite size, where larger reflect green wavelengths more intensely; this relationship could be used infer from optical signal. further successfully resolve red-shifted signal immersed refractive index liquids varying index, including values similar water or cytosol. Such lower contrast may hypothesized nanostructural forms developing The ability fainter signals hints potential facile light method for vivo analysis nanostructure butterflies.

Novel traits in the order Lepidoptera include prolegs abdomen of larvae, scales, and eyespot band color patterns wings adults. We review recent work that investigates developmental origin diversification these four from a gene-regulatory network (GRN) perspective. While eyespots appear to derive distinct ancestral GRNs co-opted novel body regions, scales situ modifications sensory bristle GRN. The basal central symmetry systems bands on wing is associated with expression WntA gene those whereas more marginal depend two other genes, Distal-less spalt . Finally, several genes have been discovered play important roles regulating background color, via regulation pigmentation GRNs. identification shared cis- regulatory elements belonging helps trace evolutionary history traits.

The earlobes of chickens exhibit a range colors, but there has been relatively little research on the formation structural blue earlobes. Previous results showed that color were related to interplay between melanin and collagen in light reflection. To investigate metabolic differences these earlobe we conducted nontargeted liquid chromatograph mass spectrometer (LC-MS) for metabolomic sequencing (Green Blue groups) nonstructural (Black group) tissue Jiangshan black-bone chickens. content detection tissues different groups shows significant Black Green group. metabolome identified total 6,102 spectroscopic peaks ultimately 919 annotated metabolites.
