Phylogenetic relationships of R2R3-MYB subgroup members from S. spontaneum and rice. A phylogenetic tree of R2R3-MYB proteins from S. spontaneum, rice, and Arabidopsis was constructed using FastTree2 with the maximum likelihood method. The sugarcane R2R3-MYB families were clustered into 15 subgroups, named G1 to G15. The subgroups were covered with colorful backgrounds. Red dots represented SsMYBs, and adjacent genes on a branch were tagged one dot
