Allopolyploid origin and niche expansion of Rhodiola integrifolia (Crassulaceae)

The dataset includes all supplementary files and sequence data set used in the article 'Allopolyploid origin and niche expansion of Rhodiola integrifolia (Crassulaceae)'. The study used phylogeny-based approach to show that R. integrifolia possesses alleles from both R. rhodantha and R. rosea. Dating analysis showed that the hybridization event that led to R. integrifolia occurred ca. 1.67 Mya and niche modeling analysis showed that at this time, both R. rosea and R. rhodantha may have been present in Beringia, providing the opportunity for the hybridization event. We also found that the niche of R. integrifolia differs from that of its progenitors in both niche breadth and optimum.
