Outline of Final Research Achievements

Momilactones serve as phytoalexins, which are responsible for disease resistance, and allelopathic substances against lowland weed. This study attempted identification of the momilactone transporter gene; screening through gene expression pattern from rice genome genes, functional analyses and other characterization of the candidate genes. However, characterization of the candidate genes has been in progress, and then identification of the targeted gene has not been accomplished. Moreover, a challenge to verify hypothesis on regulation of transporter activity through 14-3-3 interaction has been unsuccessful.
