Figure 2.

Alignment of multiple pepper MAPKK amino acid sequences from pepper and 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 conserved S/T-X5-S/T motif and active site D (I/L/V) K motif are highlighted by a red box.
