Figure 1
Distribution of leucine-rich repeat receptor kinases in Arabidopsis. (a) Histogram showing the distribution of Arabidopsis LRR-RKs by ectodomain size. The number of residues in the ectodomain is plotted versus the number of LRR-RKs found in the current reference proteome of A. thaliana. (b) Cartoon model of a putative SOBIR1–receptor-like protein (RLP)–ligand (yellow) complex at the plasma membrane (shown in grey). SOBIR1 kinase domain (green, kidney-shaped) phosphorylation is indicated with a P. Note the presence of charged stretches next to the transmembrane helices (cylinders) in SOBIR1 (positively charged, +) and different RLPs (negatively charged, −). |
