Outline of Final Research Achievements

Plant perceives light environments thorough multiple photoreceptors characteristic to plants. This study aimed to reveal the mechanisms by which molecular and cellular responses to light are integrated into the whole plant responses. For this purpose, new techniques such as laser micro-dissection were employed in addition to conventional methods. We investigated subjects such as 1) structure/function relationships in photoreceptor molecules, 2) intra-cellular light signal transduction mechanisms, 3) differential responses of various parts of the seedling and underlying mechanisms, 4) cellular responses to deformation of the cell. The work deepened our understanding about the molecular mechanisms for the plant responses to light and other stimuli.
