Evolutionary and phylogenetic analysis of the PPO family in diverse plant species. a The phylogenetic tree of PPO proteins from Aquilegia coerulea (AqcPPO), Ananas comosus (AcPPO), Amaranthus hypochondriacus (AhPPO), Carica papaya (CpPPO), Cucumis sativus (CsPPO), Eucalyptus grandis (EgPPO), Gossypium raimondii (GrPPO), Kalanchoe fedtschenkoi (KfPPO), Kalanchoe laxiflora (KlPPO), Linum usitatissimum (LuPPO), Musa acuminata (MaPPO), Malus domestica (MdPPO), Mimulus guttatus (MgPPO), Marchantia polymorpha (MpPPO), Oryza sativa (OsPPO), Oropetium thomaeum (OtPPO), Populus trichocarpa (PtrPPO), Panicum virgatum (PvPPO), Ricinus communis (RcPPO), Sorghum bicolor (SbPPO), Sphagnum fallax (SfPPO), Solanum lycopersicum (SlPPO), Spirodela polyrhiza (SpiPPO), Salix purpurea (SpPPO), and Solanum tuberosum (StPPO). The shape and color in front of the node represent the identified PPOs, in which the black circle represents MdPPOs, the black rectangle represents CsPPOs, the black pentagram represents AcPPOs, the black triangle represents MaPPOs, the red circle represents OsPPOs, the red rectangle represents SbPPOs, and the red pentagram represents StPPOs. b Comparisons of PPO protein numbers across 25 plant species. The accession numbers and gene names are all shown in Table S2
