Fig. 5: The phylogenetic tree of PKSs in Malpighiales and Solanales species.

Chalcone synthase (CHS) clade; pyrrolidine ketide synthase (PYKS) clade in Solanales; neo-pyrrolidine ketide synthase (Neo-PYKS) clade in Malpighiales; long-chain alkyl α-pyrone synthase (LCAPS) clade. The structures of the PKS products are shown in the phylogenetic tree. A fully annotated phylogram is available in Supplementary Fig. 13.
