چکیده انگلیسی
We isolated and characterized a histidine kinase gene (HIK1) from the rice blast fungus, Pyricularia oryzae (Magnaporthe grisea). The deduced amino acid sequence of HIK1 showed highest similarity (85.7%) to a hybrid-type histidine kinase, Os-1/Nik-1 of Neurospora crassa. Disruption of HIK1 caused no defect in cell growth on normal media and in pathogenicity to rice plants. The Îhik1 strain acquired resistance to three groups of fungicides (phenylpyrroles, dicarboximides, and aromatic hydrocarbons) similar to os-1 mutants of N. crassa. The Îhik1 strain showed increased sensitivity to high concentrations of sugars although its salt sensitivity was not elevated, suggesting that the rice blast fungus can distinguish osmostresses caused by high sugar concentrations and high salt concentrations. In contrast, os-1 mutants of N. crassa are sensitive to high concentrations of both salts and sugars. These findings suggest that P. oryzae and N. crassa partially differ in their os (osmosensitive) signal transduction pathway.
