Genomic divergence underlying the sky-island radiation in a mountainous biodiversity hotspot

In this study, we examined the diversification history of five endemic species to the ‘sky islands’ (mountains) of the Himalaya-Hengduan biodiversity hotspot. All of them radiated together as a clade of the genus Eutrema (Brassicaceae). We resequenced genomes of multiple individuals of all populations for each species from its narrow distributions.
