Subject of research

1. Analysis of the signal transduction pathway of chloroplast movement that is regulated by the blue light receptor phototropin
2. Analysis of molecular mechanism underlying the generation of motive force for actin-dependent chloroplast movement
3. Analysis of the chmeric photoreceptor neochrome

Elucidate the molecular mechansim how plants "move" in response to light

To maximize of photosynthetic performance under a fluctuating light environment, plants evolved various light-regulated responses. The blue light receptor-kinase phototropin mediates various light-regulated responses including chloroplast movement and phototropism. We study molecular mechanism underlying chloroplast movement. In particular, we want to reveal the signal transduction and motive force for chloroplast movement. we also study neochrome that is a chimeric photoreceptor between phytochrome and phototropin.
