Herbariomics of the Barbardos cherries: 1200 plastid genomes elucidate the tempo and mode of Malpighiaceae diversification.

The genomic era has revolutionalized the field of systematic biology by providing hundreds of loci to complete genomes to resolve branches in the tree of life. Yet rarely are such genomic tools brought to bear on complete species-level sampling of entire clades. These approaches are now possible with the advent of next generation sequencing and herbariomics. Here, we present a completely resolved plastid genome phylogeny of the ~1200 species in the tropical plant clade Malpighiaceae. Using well annotated herbarium materials we have produced a nearly comprehensive phylogeny of this group. This represents a milestone for the evolutionary and ecological investigation of this important tropical clade, and will be essential for understanding a host of questions, ranging from classification, to biogeography, to community assembly, to the origins of adaptations related to plant-pollinator mutualisms and beyond. We will present the methodologies we developed for this effort, and an outline of our initial results, including examples from four test clades which include the most species rich and taxonomically complex genera within the family.
