| Outline of Final Research Achievements |
In this study, we aimed at elucidating the roles of the space outside of the cell as a route for the movement of low-molecular-weight signaling molecules. In particular, we focused on strigolactones, which act as plant hormones and also as allelochemicals. We found that carotenoid-derived carlactone is an intermediate of strigolactone biosynthesis, and that carlactone is then converted to carlactonoic acid in Arabidopsis. We also found that a hydroxylated carlactonoic acid was detected in the xylem sap in various plant species. These results suggested that the hydroxylated carlactonoic acid might be a mobile form in the strigolactone biosynthetic pathway.
