Phylogenetic relationship of JrPP2C proteins. Alignments of 145 PP2C domains from J. regia, Populus, and Arabidopsis were performed with Clustal W. MEGA7 was used to construct a phylogenetic tree with the Neighbor-Joining method. Different colors indicate different subfamily members according to sequence similarity annotation analysis
