| Outline of Final Research Achievements |
Plants can survive under various environment conditions by responding finely to different local environmental stresses and keeping integrity as an individual. For this purpose, plants have a long-distance transport system by which local environmental signals are transported to various parts adequately. To understand this mechanism, we studied two major themes; 1) roles of CLE peptides as mediators of environmental stresses and their mechanisms, and 2) A role of vascular tissues as a long-distance transport system of local signals. As a result, we succeeded in indicating the involvement of CLE peptides in various environment stresses and demonstrating that a CLE peptide regulates stomatal closure as a mediator under drought stress. In addition, we established a method visualizing xylem signal transport, by which we revealed that nature of xylem cell walls are involved in spatiotemporal regulation of signal transport.
