The Modulation of Abiotic Stresses by Mitogen-Activated Protein Kinase in Rice
K. Nadarajah, N.M. Kasim and V.V. Fui

Abstract:
The effect of salinity, wounding and drought on the expression of a MAPK gene in rice was analyzed in this research. OrMKK2, an ortholog of the Oryza sativa japonica OsMAP1 (OsMPK5), was isolated and characterized in this study. This gene is 1381 bp long and has a 5’UTR that is 120 bp and a 3’UTR that is 195 bp and it encodes a protein that is 356 amino acids long. When analyzed against a previously isolated OrMKK1, the gene exhibited similarities in the 11 domain locations and showed 96% identity to OrMKK1. Unlike OrMKK1, the OrMKK2 gene contained two copies of the gene in the genome. OrMKK2 appeared to be positively regulated by abiotic stress.
