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.

茎顶端分生组织（SAM）创造了植物体的所有地上组织。这意味着SAM受到来自SAM外组织的信号的调节。然而，人们对这种非细胞自主信号知之甚少。在这项研究中，我专注于一种名为ERECTA的受体激酶，它与SAM的调节有关，但其SAM调节的配体尚不清楚。我成功地鉴定了ERECTA的新配体，并表明通过配体-受体对的新型细胞-细胞通讯在植物结构的调节中起着重要作用。
