Figure 2. Cis-to-trans shift events of mitochondrial introns in Tolypanthus maclurei and other representative seed plants.

The phylogenetic tree was drawn based on the phylogenies of angiosperms shown in APG IV (2016), of gymnosperms shown in One Thousand Plant Transcriptomes Initiative (2019), and of Santalales shown in Su et al. (2015). Shift events were labeled on the tree.
