| Research Abstract |
To investigate the possible involvement of acid fog as a causal factor of the rice dieback called “Suitou-Hagare-Show” that has been observed at the paddy fields with high latitudes in Nagasaki, we exposed rice plants to an acid fog in a growth cabinet and then examined the presence or absence of foliar damage as well as the gene expression profiles using the microarray method. We obtained a result of change in gene expression profile after the acid fog treatment that is similar to those reported in pathogen- or ozone-treated rice plants. By contrast, rice plants suffering from the Suitou-Hagare-Show at the paddy fields exihibited gene expression profiles that were much different from these ones, suggesting that the rice dieback would not have been caused by a single factor such as acid fog
