NgRLK1 amino acid sequence and its predicted domain structure. a Amino acid sequence alignment of NgRLK1 with members of the receptor-like kinase family. Identical amino acids are represented by solid black lines. Spaces indicate gaps introduced to maximize the alignment. The other RLKs are indicated by their EMBL accession numbers: NP_198644 (Arabidopsis thaliana), O49974 (Zea mays), P93068 (Brassica oleracea), and Q9LLN5 (Oryza sativa). b Schematic representation of NgRLK1 based on a conserved domain analysis. SP, signal peptide; TM, transmembrane
