Priming of pearl millet seedlings with nitric oxide (NO) donors sodium nitroprusside (SNP) and S-nitrosoglutathione (SNOG) induced hypersensitive reactions (HR) and accumulation of Proline/Hydroxyproline-rich glycoprotein (P/HRGP) during infection by downy mildew pathogen Sclerospora graminicola. Such defense responses were specifically altered by concentration of NO donors resulting in the modulation of endogenous NO in seedling tissues. The stoichiometric interactions of NO and hydrogen peroxide (H2O2) when followed in relation to HR and P/HRGP accumulation, the degree of defense response varied with H2O2 level, the latter being largely influenced by NO concentration. Therefore, balancing NO and H2O2 is vital for optimum expression of defense responses for imparting disease resistance. (C) 2009 Elsevier Ltd. All rights reserved.
