Effect of Methyl Jasmonate on Harpin-Induced Hypersensitive Cell Death, Generation of Hydrogen Peroxide and Expression of PAL mRNA in Tobacco Suspension Cultured BY-2 Cells
Laboratory of Plant Pathology and Genetic Engineering, Faculty of Agriculture, Okayama University, 1-1-1, Tsushima, Okayama, 700-8530 Japan
Methyl jasmonate inhibited the harpin-induced defense responses such as cell death, H2O2 generation and gene expression encoding phenylalanine ammonia-lyase in tobacco suspension cultured BY-2 cells. These results suggest that MeJA may act as an endogenous suppressor for plant defense response including hypersensitive reaction.
