Figure 1.

Multiple sequence alignment of the amino acid sequences of pepper MAPKs and MAPKs from other plant species (tomato, Arabidopsis, and rice). The alignment was performed using Clustal X. The 11 conserved domains (I–XI) present in pepper serine/threonine protein kinases are denoted by Roman numerals. The activation loop region is marked by a black line. The conserved threonine and tyrosine residues are indicated by asterisks.
