Phylogenetic analysis of SWEETs proteins from D. officinale, A. thaliana, O. sativa and P. equestris. The un-rooted phylogenetic tree was constructed using Maximum Likelihood Estimate method in MEGA 11. The bootstrap value was set as 1000 replicates. Percentages of replicate trees in which the associated sequences clustered together in the bootstrap test are shown next to the branches. Clade I, II, III, and IV are marked by green, gray, blue, and purple, respectively. DoSWEETs are marked in red stars. The abbreviations of species names are as follows: Do, Dendrobium officinale; At, Arabidopsis thaliana; Os, Oryza sativa; the proteins started with PA are PeSWEETs from Phalaenopsis equestris
