Reconstructing Dipsacales phylogeny using Angiosperms353: issues and insights.

ABSTRACT:

Premise

Phylogenetic relationships within major angiosperm clades are increasingly well resolved, but largely informed by plastid data. Areas of poor resolution persist within the Dipsacales, including placement of Heptacodium and Zabelia, and relationships within the Caprifolieae and Linnaeeae, hindering our interpretation of morphological evolution. Here, we sampled a significant number of nuclear loci using a Hyb-Seq approach and used these data to infer the Dipsacales phylogeny and estimate divergence times.

Methods

Sampling all major clades within the Dipsacales, we applied the Angiosperms353 probe set to 96 species. Data were filtered based on locus completeness and taxon recovery per locus, and trees were inferred using RAxML and ASTRAL. Plastid loci were assembled fr
