| Outline of Final Research Achievements |
Physiological function of monomeric abscisic acid (ABA) receptors among ABA receptor has not been revealed. We have developed ABA sensor using yeast two-hybrid system, and it’s sensor was used for finding selective ABA agonist to monomeric receptor. As the result, we found 115C07 compound, which inhibited only hypocotyl growth in the dark condition. Chemical genetic screens with 115C07 have identified PYL8, ABI3, ABI4, RNA processing and kinase component mutants, suggesting that these components are involved in tissue specific plant growth.
