Gene structure and sequence features of conserved MAPKK genes. (a) Gene structure and protein motif. The structure of an A.thaliana gene (indicated on the left) is shown as an example for each group (in parenthesis on the left). Protein motifs are shown as colored boxes, whereas introns of different phase are shown as colored vertical lines. Protein motif architectures of the full-length proteins were drawn based on a search of InterPro program. IPR002290 indicates protein kinase motif, IPR017441 and IPR008271 means the ATP binding site and active site, respectively. The exons are drawn to scale. (b) Sequence features shown in the form of web logos representing the conserved S/T-X5-S/T motif and active site D(I/L/V)K motif of each group. The red and green stars indicate residues of functional or structural importance based on phylogenetic conservations. Logos were generated using the Weblogo3 application (http://weblogo.threeplusone.com/). (c) Multiple-sequence alignment of conserved S/T-X5-S/T motif and active site D(I/L/V)K motif portion of plant MAPKKs. The green star shows the active site and the red star indicate the phosphorylation site of MAPKK proteins in different plant species. Species information can be found in Additional file 1
