Prediction of the amino acid sequence and protein structure of the LRR-RLK XIK1. The sequence from amino acid residue 1 to 26 is predicted as a signal peptide. The extra-cellular region with 17 LRRs consists of the amino acid residues from 28 to 422; the amino acids characterizing the LRR motifs are marked in dark. The transmembrane region consisting of amino acid residues from 486 to 509 are underlined with single solid line. The intracellular kinase domain consisting of the amino acid residues from 550 to 802, with the conserved amino acid residues is indicated by double lines. The structure of XIK1 was predicted according to the structure of XA21 reported previously (G. L. Wang et al. 1996; Xiang et al. 2006).
