Using RAD-seq to infer phylogeny of a rapid radiation of a subalpine everygreen shrub (Berberis sect. Wallichianae, Berberidaeae) in Taiwan.

Berberis sect. Wallichianae in Taiwan can be found in subalpine and montane-temperate areas. Most of them are morphologically and ecologically different, only few are sympatry. Previous phylogenetic study based on three chloroplast DNA sequences region (rbcL, ycf6-psbM and psdA-trnH) strongly support them, 11 species, as a monophyletic group endemic to Taiwan, but the phylogenetic relationship among them in the radiation are unresolved. Here we sample all of Taiwanese endemic species (i.e., B. aristatoserrulata, B. brevisepala, B. chingshuiensis, B. hayatana, B. kawakamii, B. mingetsensis, B. nantoensis, B. pengii, B. ravenii, B. schaaliae, and B. tarokoensis) and two species (i.e., B. baradana and B. wuyiensis) respectively endemic to Philippines and China, as the out groups. To test the species hypothesis and determine phylogenetic relationships among them using restriction site-associated DNA sequencing (RAD-seq). We identify great number of SNPs and construct the will-supported phylogentic tree from the RAD data. The result indicate the evolutionary history of Berberis sect. Wallichianae in Taiwan to clarify their relationship and also confirm the utility of RAD data for reconstructing phylogenetic relationships in young and rapid lineages.
