title: Synthesizing existing phylogenetic data to advance phylogenetic research in Orobanchaceae

description: To date, no comprehensive phylogenetic analyses have been conducted in
 Orobanchaceae that include both a wide generic sampling and a large
 sampling of species. In addition, a lack of fossil evidence in the clade
 precludes the use of primary fossil calibrations for divergence time
 estimation, preventing the establishment of a comprehensive temporal
 framework for use in macroevolutionary studies. Here, we use a recently
 developed set of tools for synthesizing publicly available data, apply
 these to reconstruct a comprehensive timetree for Orobanchaceae, and then
 investigate diversification dynamics in this clade of mostly parasitic
 plants using two model based methods. The assembled supermatrix included
 more than 900 species, representing approximately 40% of the known species
 diversity of the family, and the resulting phylogeny largely confirmed
 relationships revealed in earlier studies; however, we identified ten
 non-monophyletic genera that will require focused systematic attention to
 resolve. Diversification rate analyses found substantial support for
 character-dependent diversification, with elevated rates in hemiparasitic
 clades, and evidence for a number of speciation rate changes throughout
 the tree that are likely linked to other traits. Importantly, our
 multi-state HiSSE analysis revealed that transitions to a parasitic
 lifestyle only occur when there is a prior transition in an unobserved
 precursor state.  For Orobanchaceae, our study provides a new
 comprehensive framework for the clade that can serve as a stepping-stone
 for future macroevolutionary studies.
