Data from: Plastid phylogenomics of the tribe potentilleae (Rosaceae)

The tribe Potentilleae comprises approximately 1700 species in 13 genera,
making it one of the largest of the 16 tribes in Rosaceae. Our
understanding of the composition and relationships among members of
Potentilleae has advanced dramatically with the application of molecular
markers in the last two decades. Yet there is still much work remaining
toward a robust phylogenetic framework for the entire Potentilleae and a
comprehensive genus-level dating framework for the tribe. The goals of the
present study were to establish a phylogenetic framework for Potentilleae,
infer the origin and diversification of the tribe using a temporal
framework, and explore the taxonomic implications in light of the updated
phylogenetic framework. We used the plastome sequences from 158 accessions
representing 139 taxa covering all 13 recognized genera of the tribe to
reconstruct the Potentilleae phylogeny. High phylogenetic resolution was
recovered along the Potentilleae backbone. Two major clades were recovered
within Potentilleae, corresponding to two subtribes Fragariinae and
Potentillinae. Within Fragariinae, two subclades were recovered. In one
subclade, Sibbaldia sensu stricto is sister to a clade containing
Sibbaldianthe, Comarum, Farinopsis, and Alchemilla sensu lato. In the
other subclade, Fragaria is sister to a clade comprising Chamaerhodos,
Chamaecallis, Drymocallis, Dasiphora, and Potaninia. Within Potentillinae,
Argentina is sister to Potentilla sensu stricto. Within Potentilla sensu
stricto, clade Himalaya is sister to Alba, and the Himalayan-Alba clade
together is sister to a clade comprising Reptans, Potentilla ancistrifolia
Bunge, Fragarioides, Ivesioid, and Argentea. Divergence time estimates
indicated that tribe Potentilleae originated during the middle Eocene, and
subtribes Fragariinae and Potentillinae diverged around the
Eocene-Oligocene transition, and divergence times dated for Potentilleae
genera ranged from the early Miocene to the late Pleistocene.
