Phylogenetic analysis of SDGs in D. catenatum, P. equestris, Arabidopsis and rice. This tree includes 44 SET domain-containing proteins from D. catenatum, 42 from P. equestris, 49 from A. thaliana and 46 from O. sativa. The 181 SET domain-containing proteins were divided into eight classes combined with the further phylogenetic analysis in Fig. 4. SDGs amino acid sequences were aligned using Clustalx, and the phylogenetic tree was constructed using MEGA7 with the following settings: Tree Inference as Neighbor-Joining (NJ); Include Sites as Pairwise deletion option for total sequence analyses; Substitution Model: p-distance; and Bootstrap test of 1000 replicates for internal branch reliability. Bootstrap values > 50% are shown. Dc, D. catenatum; Pe, P. equestris; At, A. thaliana; Os, O. sativa
