TL;DR: This work investigates an unprecedented reorganization of the standard lepidopteran chromosome structure in the green-veined white butterfly (Pieris napi) and finds that gene content in P. napi has been extensively rearranged in large collinear blocks, suggesting both a mechanism and a possible role for selection in determining the boundaries of these genome-wide rearrangements.
Journal ArticleDOI
A transposable element insertion is associated with an alternative life history strategy.

TL;DR: A transposable element insertion is associated with the switch between alternative life history strategies, central to life history theory and evolutionary biology, and characterize one such mechanism for a female-limited ALHS.
Journal ArticleDOI
Evolutionary history of host use, rather than plant phylogeny, determines gene expression in a generalist butterfly.

TL;DR: The findings suggest that V. cardui may use two sets of expressed genes to achieve polyphagy, one associated with the ancestral capability to consume Rosids and Asterids, and another allowing the caterpillar to incorporate a wide range of novel host-plants.
Journal ArticleDOI
Investigating the genomic basis of discrete phenotypes using a Pool-Seq-only approach: New insights into the genetics underlying colour variation in diverse taxa.
TL;DR: Using Pool‐Seq data for both genome assembly and SNP frequency estimation, followed by scanning for FST outliers to identify divergent genomic regions, new regions of high divergence and new annotations are discovered that together suggest novel parallels between birds and butterflies in the origins of their colour pattern variation.

A butterfly chromonome reveals selection dynamics during extensive and cryptic chromosomal reshuffling

TL;DR: Extensive chromosomal rearrangements in the genome of the green-veined white butterfly are reported, revealing that the evolutionary dynamics acting on Lepidopteran genome structure are more complex than previously envisioned.
