Outline of Final Research Achievements	5-aminolevulinic acid (ALA) is a key precursor in the biosynthesis of tetrapyrroles in plants. Feeding ALA to plants can induce an excess accumulation of some porphyrins. In addition, ALA has some effects on increasing biomass and photosynthetic activity, and enhancing stress tolerance such as cold and salt in agriculture. I attempted whether ALA has the effect on enhancing plant immune response in Arabidopsis thaliana as a model. As a result, I found that several genes involved in immune response were induced in the presence of ALA, and different gene expression patterns were obserbed.
