Data from: Evolution of multiple sex-chromosomes associated with dynamic genome reshuffling in Leptidea wood-white butterflies
<p>Sex chromosome systems tend to be highly conserved and knowledge about their evolution typically comes from macroevolutionary inferences. Rapidly evolving complex sex chromosome systems represent a rare opportunity to study the mechanisms of sex chromosome evolution at unprecedented resolution. Three cryptic species of wood white butterflies – <i><span>Leptidea juvernica</span></i>, <i><span>L. sinapis</span></i>, and <i><span>L. reali</span></i> – have each a unique set of multiple sex chromosomes with 3–4 W and 3–4 Z chromosomes. Using a transcriptome-based microarray for comparative genomic hybridization (array-CGH) and a library of bacterial artificial chromosome (BAC) clones, both developed in <i><span>L. juvernica</span></i>, we identified Z-linked <i><span>Leptidea</span></i> orthologs of <i><span>Bombyx mori</span></i> genes and mapped them by fluorescence <i><span>in situ</span></i> hybridization (FISH) with BAC probes on multiple Z chromosomes. In all three species, we determined synteny blocks of autosomal origin and reconstructed the evolution of multiple sex chromosomes. In addition, we identified W-homologs of Z-linked orthologs and characterized their molecular differentiation. Our results suggest that the multiple sex chromosome system evolved in a common ancestor of these three <i><span>Leptidea</span></i> species as a result of dynamic genome reshuffling through repeated rearrangements between the sex chromosomes and autosomes, including translocations and fissions. Thus, the sex chromosome turnover could not play a role in reproductive isolation between the <i><span>Leptidea </span></i>species studied. However, we suggest that subsequent species-specific rearrangements of multiple sex chromosomes, along with different rates of neo-W chromosome degeneration and significantly increased number of Z-linked genes could accelerate the accumulation of genetic incompatibilities between populations and promote their divergence resulting in speciation.</p>
