A plastome-based phylogeny for the Orchidaceae.

As part of the Monocot AToL project, we are sequencing the entire plastid genome of species representing each subfamily, each tribe, and most subtribes of the Orchidaceae. The resulting data set should provide an extremely powerful means for inferring the evolutionary history of orchids. We will use these data to conduct a test of recent phylogenetic hypotheses based on two , three, and eight plastid genes and on morphology. We will also use the plastome tree to estimate the time of divergence of orchids from their nearest relatives among early-divergent lineages of the order Asparagales. An analysis of support for individual nodes in the tree as a function of the number of genes, introns, spacers, and bases included will be used to assess minimum requirements for a well-resolved orchid phylogeny.
