| Outline of Final Research Achievements |
Cytosolic calcium ions function as an important second messenger in guard cell signaling that regulates stomatal movement. However, the molecular mechanism that regulate cytosolic calcium ion concentrations in guard cells and the downstream mechanism responsible for calcium sensing are not yet fully understood. In this study, we analyzed the functions of novel candidate factors for calcium ion transporters involved in the regulation of stomatal movement, providing important insights into the regulatory mechanisms of plant stress tolerances.
