—A comparison of plastid genome size and the number of putatively functional genes for sequenced holoparasites (gray), full mycoheterotrophs (black), and selected autotrophs (including partial mycoheterotrophs and hemiparasites; green), with trophic status based on whether or not photosynthetic genes are putatively functional in each.
