Abstract

In this study, we describe the gene that codes for MAPK in Oryza rufipogon and Oryza sativa that reacts towards the blast disease (causative agent is Magnaporthe grisea) and brown planthoppers (Nilaparvata lugens). This gene has been isolated and characterized in Oryza sativa and in this study the same gene has been isolated from Oryza rufipogon using OsMKKl as a template and named OrMKKl. Through conducting this study, we found that Oryza rufipogon contains two copies of the MAPK gene in its genome. A comparative study was conducted between OrMKKl and OsMKKl; and the results showed that both these genes responded towards biotic stress. Though both the genes share a high level of amino acid similarities (94%), the kinetic reactions of both genes are different.
