A phylogeny of the evening primrose family (Onagraceae) using a target enrichment approach with 303 nuclear loci
The evening primroses (Onagraceae) include 664 species (803 taxa) with a center of diversity in the New World, especially western North America. Ongoing research in Onagraceae includes exploring striking variation in floral morphology, scent composition, and breeding system, as well as the role of these traits in driving diversity among plants and their interacting pollinators and herbivores. However, these efforts are limited by the lack of a comprehensive, well-resolved phylogeny. Previous phylogenetic studies based on a few loci strongly support the monophyly of the family and the sister relationship of the two largest tribes but fail to resolve several key relationships. These data were generated using a target enrichment approach to reconstruct the phylogeny of Onagraceae using 303 highly conserved, low-copy nuclear loci from 169 individuals representing 152 taxa sampled across the family, including extensive sampling within tribe Onagreae.
