Clustering analysis of Arabidopsis CLE motifs. Phylogenetic tree of AtCLE motifs (a), full-length proteins without signal peptides (b) and log-normalized rank of all-vs-all BLAST e-values generated using the NJ method based on the evolutionary distances (c), which were computed using the Poisson correction method (a, b), and Euclidean distances (c). d Clustering of the AtCLE motifs based on the Euclidean distance of each pair of sequences in a site-weight dependent manner. The tree was constructed using the HCL method. The names of the CLE motifs are indicated with different colors
