Work Experience1. Study on Rooting of Woody Plants: Roles played by phytohormones such as IAA, ABA, CK and ethylene, in rooting of woody plants were investigated. It is found that the initiation of adventitious roots is controlled by phytohormones. The results demonstrated that lack of endogenous hormones, especially CK is responsible for hard-to-rooting of many woody plants. 2. Phototropism of High Plants: Phototropism of Maize and Arabidopsis were studied during my Ph.D. study in Japan. It was uncovered that phytochrome, a photoreceptor responsible for many photomorphogenic responses induced by red and far-red light, is also involved in the process perceiving the signal of blue light by plants. 3. Photomorphogenesis, Photoecology of Forestry. The project is now undertaken. We expect to solve several problems on utility of photon energy in forestry by using phytochrome mutants and techniques of molecular biology.
