| Research Abstract |
The shoot apical meristem(SAM) creates all above-ground tissues of plant body. It is implied that the SAM is regulated by signals that is originated in tissues outside the SAM. However, little is known about such a non-cell-autonomous signals. In this research, I focused on a receptor-kinase called ERECTA, which has been implicated in regulation of the SAM but its ligand for the SAM regulation is unclear. I succeeded in the identification of new ligands for ERECTA and showed that the novel cell-cell communication via the ligand-receptor pair plays a significant role for the regulation of plant architecture.
