Outline of Final Research Achievements

In this study, the dynamic relationships between leaf spectral reflectance and the expression of genes involved in plant disease resistance were investigated for Arabidopsis treated (irrigated) with MgO nano-particle aqueous suspension to acquire knowledge on nondestructive evaluation of disease resistance induced by abiotic stress. The pathogenesis-related protein 1 (PR1) gene expression was enhanced in leaves of plants treated by MgO suspension as compared with those treated with water. The leaf spectral reflectance pattern was also changed with MgO treatment. These results suggested that leaf spectral reflectance might have a potential to be used for nondestructive evaluation of the induced disease resistance status.
