Plants produce plant hormones to regulate plant growth and development in response to biotic or abiotic stresses. The plant hormones interact with each other to control physiological phenomena. Although many researches indicated that plant hormone interactions occur at the level of hormone biosynthetic and signaling pathway, common targets of multiple hormones are little known. In this research, we aimed to develop chemicals that inhibit the common targets in the phytohormone signaling. For this purpose, we use epicotyl section of azuki bean seedling. Its elongation is promoted by exogenously applied brassinosteriod, auxin and gibberellins. We selected the first candidates that show inhibitory effects to the synergistic functions of at least two hormones from a commercially available chemical library. At present, some of these candidates are subjected to the next experiment using Arabidopsis seedling.
