Figure 4. Phylogenetic analyses of Tolypanthus maclurei and other 37 angiosperms based on sequences of two regions of mitochondrial atp1.

(A) Maximum likelihood tree for region I. (B) Maximum likelihood tree for region II. Gaiadendron, Amyema and Tapinanthus were excluded because their region II of atp1 are too short (<50 bp) with available sequences. Bootstrap support values ≥ 50% are shown above the branches. Hemiparasitic and autotrophic species in Santalales are shown in orange and green, respectively.
