Amino acid sequence of three L. esculentum MAPKs. A, The deduced
amino acid sequences of LeMPKs 1, 2, and 3 were aligned. Identical and
conserved amino acids are shaded in black and gray, respectively. Dots
represent gaps. Roman numerals represent the 11 conserved kinase subdomains.
Asterisks show the Thr and Tyr residues in the TEY phosphorylation motif. The
solid line, the dotted line, and the dashed line represent the sequences used
as antigenic peptides to generate specific antibodies against LeMPKs 1, 2, and
3, respectively. B, A phylogenetic tree shows the relationship among the A2
group of plant MAPKs (Ichimura et al.,
2002). C, A phylogenetic tree shows the relationship among the A1
group of plant MAPK (Ichimura et al.,
2002). The tree was created by the GrowTree method from the GCG
Wisconsin Package. Accession numbers: StMPK1, AB062138; StMPK2, AB062139;
