Long noncoding RNAs (lncRNAs) are transcribed elements increasingly recognized for their roles in regulating gene expression. Thus far, however, we have little understanding of how lncRNAs contribute to evolution and adaptation. Here, show that a conserved lncRNA, ivory , is an important color patterning the buckeye butterfly Junonia coenia . overlaps with cortex locus linked multiple cases crypsis mimicry Lepidoptera. Along companion paper by Livraghi et al., argue not pattern interest at this locus. In J. cluster cis -regulatory (CREs) first intron genetically associated natural variation seasonal plasticity, targeted deletions these CREs phenocopy phenotypes. Deletions different produce other distinct phenotypes as well, including loss melanic eyespot rings, positive negative changes overall wing pigmentation. We transcription factors Spineless, Bric-a-brac, Ftz-f1 bind promoter during development, suggesting they directly regulate This case study demonstrates -regulation single RNA can exert diverse nuanced effects on development patterns, modulating seasonally plastic patterns.

Abstract 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 , where both derive from an epithelial precursor specified by lateral inhibition then undergoes multiple rounds division. Previous histological examination candidate gene approaches identified parallels genes involved scale bristle development. Here, we provide definitive developmental transcriptomic evidence differentiation lepidopteran derives canonical cell lineage, known as Sensory Organ Precursor (SOP). Live imaging moth butterfly pupae shows SOP cells undergo two asymmetric divisions first abrogate neurogenic lead a differentiated its associated socket cell. Single-nucleus RNA sequencing across time-series early pupal development revealed differential expression patterns mirror lineage development, including Notch-Delta signalling components, adhesion molecules, cycling factors, terminal markers, suggesting shared program. Additionally, recovered novel gene, POU-domain transcription factor pdm3 proper wing scales. Altogether, these data open up avenues for understanding type specification illustrate how single-cell transcriptomics powerful platform evolution types.

The extent to which evolution is repeatable has been a debated topic among evolutionary biologists. Although rewinding the tape of life perhaps would not lead same outcome every time, repeated analogous genes for similar functions extensively reported. Wing phenotypes butterflies and moths have provided wealth examples gene re-use, with certain ‘hotspot loci’ controlling wing patterns across diverse taxa. Here, we present an example convergent in molecular genetic basis Batesian mimicry two Hypolimnas butterfly species. We show that controlled by variation near cortex/ivory/mir-193 , known hotspot locus. By dissecting architecture misippus bolina evidence distinct non-coding regions control development white pattern elements forewing hindwing species, suggesting independent evolution, no structural found at Finally, also orange coloration H. associated optix, well-known patterning gene. Overall, our study once again implicates loci optix thereby highlights repeatability adaptive evolution.
