Outline of Final Research Achievements

Metabolomics analysis of drought tolerant plant, Jatropha curcas, revealed drought responsive accumulation of osmolytes such as proline, raffinose and amino acids. We cloned key genes for their biosynthesis from J. curcas, and introduced them into Arabidopsis; however, enhanced drought tolerance in the transformants was not obtained. We also constructed gene expression vectors for production of stress tolerant plants using tissue-specific, stress-inducible, and constitutive promoters from Arabidopsis.
