Phylogenetic and biogeographic analyses were conducted to provide insights into the evolution and historical biogeography of East Asian taxa in the Campanuloideae (Campanulaceae). A molecular dataset including nuclear PPR70 gene sequences and five plastid regions (atpB, matK, petD, rbcL, and trnL-trnF) was assembled.

Data: 1 - Area matrix for biogeographic analysis in BioGeoBears; 2 - Plastid alignment for phylogenetic analysis; 3 - Nuclear (PPR70) alignment for phylogenetic analysis; 4 - Plastid plus nuclear (PPR70) combined alignment for phylognetetic analysis;
