Fig. 1: Phylogenetic tree of glutathione S-transferase (GST) proteins in apple, Arabidopsis thaliana, maize, and dragon’s blood tree (Dracaena draco).
From: MdGSTF6, activated by MdMYB1, plays an essential role in anthocyanin accumulation in apple

The 69 apple, 63 A. thaliana, 29 maize, and 20 D. draco GST protein sequences were aligned using Clustal W. The phylogenetic tree was constructed based on the neighbor-joining algorithm. GST proteins were clustered into nine classes. The protein sequences are listed in Table S3
