Cortex cis-regulatory switches establish scale colour identity and pattern diversity in Heliconius

L Livraghi, JJ Hanly, SM Van Bellghem… - Elife, 2021 - elifesciences.org
In Heliconius butterflies, wing colour pattern diversity and scale types are controlled by a few
genes of large effect that regulate colour pattern switches between morphs and species …

Distal-less and spalt are distal organisers of pierid wing patterns

JLQ Wee, T Das Banerjee, A Prakash, KS Seah… - EvoDevo, 2022 - Springer
Abstract Two genes, Distal-less (Dll) and spalt (sal), are known to be involved in establishing
nymphalid butterfly wing patterns. They function in several ways: in the differentiation of the …

Reuse of an insect wing venation gene-regulatory subnetwork in patterning the eyespot rings of butterflies

TD Banerjee, A Monteiro - BioRxiv, 2021 - biorxiv.org
Novel organismal traits might reuse ancestral gene-regulatory networks (GRNs) in their
development, but data supporting this mechanism are still sparse. Here we show the reuse …

Conserved signaling pathways antagonize and synergize with co-opted doublesex to control development of novel mimetic butterfly wing patterns

NW VanKuren, MM Doellman, SI Sheikh, DHP Droguett… - bioRxiv, 2022 - biorxiv.org
Novel phenotypes are increasingly recognized to have evolved by co-option of existing
gene regulatory networks (GRNs) into new developmental contexts, yet the changes …

A complex interplay between balancing selection and introgression maintains a genus-wide alternative life history strategy

K Tunström, A Woronik, JJ Hanly, P Rastas… - BioRxiv, 2021 - biorxiv.org
Alternative life-history strategies (ALHS) are genetic polymorphisms generating phenotypes
differing in life histories that generally arise due to metabolic resource allocation tradeoffs …

The gene cortex controls scale colour identity in Heliconius

L Livraghi, JJ Hanly, LS Loh, A Ren, IA Warren… - bioRxiv, 2020 - biorxiv.org
The wing patterns of butterflies are an excellent system with which to study phenotypic
evolution. The incredibly diverse patterns are generated from an array of pigmented scales …

Butterfly wings exhibit spatial variation in chromatin accessibility

H Connahs, M das Gupta, A Monteiro - bioRxiv, 2022 - biorxiv.org
Butterfly wings exhibit a diversity of patterns which can vary between forewings and
hindwings and spatially across the same wing. Regulation of morphological variation …

Comparative Studies of Spot and Eyespot Patterns in Butterflies

WLQ Jocelyn - 2021 - search.proquest.com
One of the central tenets of evolution is the concept of 'descent with modification'. All novel
morphological structures must have been ultimately, derived from more primitive forms …
