Outline of Final Research Achievements

Stomata in the plant epidermis open in response to blue light and contribute to plant growth by regulating photosynthesis and transpiration. A blue light-receptor phototropin mediates the stomatal opening via promotion of an active transport of K+ in stomatal guard cells. However, signaling for the stomatal opening is not fully understood. In this study, we performed functional analysis of a protein kinase that interacts with phototropin, and characterized roles of the protein kinase in the blue light signaling for stomatal opening.
