The mitogen-activated protein kinase (MAPK) cascade is one of the major and evolutionally conserved signaling pathways and plays pivotal role in the regulation of stress and developmental signals in plants. Here, a novel gene, termed Gossypium hirsutum MAPK (GhMAPK), was isolated from cotton. The full-length cDNA of GhMAPK encodes for a 372 amino acid protein that contains all 11 of the MAPK conserved subdomains and the phosphorylation-activation motif, TEY. Amino acid sequence alignment revealed that GhMAPK shared high identity with group-C MAPK in plants and showed 83~89% similarities with MAPKs from Arabidopsis, apricot, pea, petunia, and tobacco.
