| Research Abstract |
Phototropin is a chromoprotein of about 100 kDa mediating various blue-light responses such as phototropism, chloroplast positioning and stomata opening. In this study, we aimed to elucidate the molecular mechanism by which phototropin regulates the plant movement. For this purpose, we conducted a structure/function study of phototropin to identify important substructures of the molecule and their functions. In addition, we investigated putative signaling components of the phototropin signal trasduction and have fund that vesicle trafficking plays a crucial role in these responses.
