Fig. 3.

Rooted phylogenetic tree of the 17 species WRKY families. A total of 1308 WRKY proteins of 17 species were constructed the rooted phylogenetic tree by OrthoFinder (v2.2.3), the blue color represented dicotyledons and violet color represented monocotyledons, the green color represented magnolias, and the red color was represented basal angiosperms. The scale bar indicates the branch length of the phylogenetic tree. The picture on the right panel was the picture corresponding to each species, and the name of the family of each species was annotated on the corresponding branch of the evolutionary tree
