Outline of Final Research Achievements

We have isolated a flower-inducing compound, LDS1, from a free-floating aquatic plant, Lemna paucicostata. To afford the sufficient amounts of LDS1, we successfully synthesized LDS1. We also synthesized LDS1 analogs by modifying carbon-chain length, number of hydroxyl groups, kept-reduction, position of double bounds to investigate structure-activity relationships. By using the LDS1 chemically synthesized, we have analyzed metabolic pathways for LDS1 in Lemna plants. One of the metabolites was tentatively identified as a reduction product of LDS1 in its double bound. Substantial amounts of LDS1 was produced in Lemna plants grown in the high-density stress conditions.
