| Outline of Final Research Achievements |
Stomata open in response to blue light, and the opening is mediated by a phototropin-activated proton pump and a consequent potassium uptake in stomatal guard cells. However, signaling for the stomatal opening is not fully understood. In this study, we performed a protein-protein interaction screening and identified CIPK23 as a phototropin interactor. As the results of functional analyses of CIPK23, we found that CIPK23 mediates stomatal opening not through the proton pump activation but through the potassium channel activation in guard cells.
