| Outline of Final Research Achievements |
Osmotic stress responses are important mechanisms of early stress perception for adapting abiotic stress conditions including drought stress. One of the protein kinases, SnRK2, is a key phosphorylation enzyme, and activated by osmotic stress conditions. This activation leads to the accumulation of one of the important phytohormone, abscisic acid (ABA), and the acquisition of stress resistance in planta. However, there remain unclear the perception mechanism of osmotic stress conditions. In this study, we focused on one of the small peptides mediating the activation of SnRK2 protein kinase. We analyzed the perception mechanisms of early osmotic stress conditions. Especially we elucidated the peptide signaling mediating cell-to-cell communications in response to early osmotic stress responses.
