Analysis of conserved motifs, gene structure and domains in the CrRLK1L genes of N. benthamiana. a Phylogenetic tree constructed using the NbCrRLK1L protein sequences. b 10 types of conserved motifs predicted in the NbCrRLK1L protein sequences. The different motifs are shown in different color boxes. The sequence information for each motif is provided in Additional file 2: Table S2. c The gene structure of NbCrRLK1L members. Untranslated regions, exons, and introns are shown as light blue boxes, light green boxes and horizontal lines, respectively. The red and yellow boxes represent the Malectin-Like Domain (MLD) and Protein Kinase Domain (PK) respectively
