Genomic architecture of a genetically assimilated seasonal color pattern

Résumé fourni par la source

Untangling the genetics of plasticity The common buckeye butterfly, Junonia coenia , exhibits plastic coloration; it has two color morphs, light tan and dark red, that depend on day length and temperature. By selecting for more and less color plasticity, van der Burg et al. generated butterfly lines that were used to map the genetic variants that underlie differential coloration. Genome-wide analysis and RNA sequencing identified the genes most likely to be associated with the differences in color plasticity. Inactivation of genes with CRISPR–Cas9 identified three genes that affected the red phenotype, and other techniques identified cis-regulatory, noncoding genomic variants that were correlated with coloration. From these results, the authors were able to model how genetically encoded plasticity and assimilation of the plastic trait likely evolved. Science , this issue p. 721
