A phylogenomic approach to decode contentious relationships across all angiosperm families.

Here we describe the first (order- and) family-complete phylogenomic analysis across all angiosperms. We demonstrate that the angiosperms 353 kit we developed, in the context of the Plant and Fungal Trees of Life (PAFTOL) project (https://www.kew.org/science/our-science/projects/plant-and-fungal-trees-of-life), works to enrich up to 353 nuclear orthologs for all angiosperm families. Additionally, we recover organellar off-target coding regions as well as non-coding introns, the latter of use to resolve relationships at shallow levels, e.g. genera and species. Our phylogenomic pipeline explores effects of alignment, trimming, partitioning, gene tree inference, and species tree inference on our phylogenetic reconstruction. Recalcitrant nodes are explored in light of recent support measures to discuss robustness of alternative contentious relationships and present a backbone hypothesis for the flowering plant tree of life.
