The columbine genus Aquilegia is a classic example of an adaptive radiation, involving wide variety pollinators and habitats. Here we present the genome assembly A. coerulea 'Goldsmith', complemented by high-coverage sequencing data from 10 wild species covering world-wide distribution. Our analyses reveal extensive allele sharing among demonstrate that introgression selection played role in radiation. We also remarkable discovery evolutionary history entire chromosome differs rest - phenomenon do not fully understand, but which highlights need to consider chromosomes context.
