Phylogenetic tree of LRR-RLK from Arabidopsis thaliana and two founding Saccharum species. A phylogenetic tree of LRR-RLK proteins from Saccharum spontaneum, Saccharum officinarum, and Arabidopsis thaliana was constructed using FastTree2 with the maximum likelihood method. The two founding Saccharum LRR-RLK families were clustered into 15 subgrups. The different colored arcs indicate different groups (or subgroups) of the LRR-RLK genes. The labels marked in black color represent Saccharum spontaneum, blue color represent Saccharum officinarum, and red color represent Arabidopsis thaliana
