The sequential characteristics of the variable residues in the inside of the superhelix. The footprints of residues along the inner side of the LRR stacks in seven homolog clades (Fig. S2 and S3) are shown. Red bars indicated LRR areas involved in ligand binding according to LRR-ligand complexes: BRI1 (PDB 4M7E), PSKR1(PDB 4Z61), PEPR1 (PDB 5GR8), HAE (PDB 5IXQ), RGFR (PDB 5Z21), TDR/PXY (PDB 5GIJ), and FLS2 (PDB 4MN8). The conserved RxR motifs in sequences belonging to SG_xi are highlighted in magenta boxes
