Abstract

Receptor-like kinases (RLKs) play important roles in multiple aspects of plant growth and development. As a member of the TNFR-like RLK subfamily, rice Crinkly4 (OsCR4) functions mainly in epidermal cell differentiation in many organs. Here we show that in addition to its essential role in epidermal cell differentiation in the palea and lemma, OsCR4 positively regulates rice culm elongation, similar to maize CR4. Although OsCR4 is an active kinase, like CR4 in maize and ACR4 in Arabidopsis, the conserved amino acid K532 in OsCR4 is not essential for its kinase activity in vitro. Whether other conserved amino acids are required for its kinase activity and the relationship between its activity and function in plant development remain to be investigated.

摘要

受体样激酶（RLKs）在植物生长和发育的多个方面发挥着重要作用。作为 TNFR 样 RLK 亚家族的一员，水稻卷曲 4（OsCR4）主要在许多器官的表皮细胞分化中起作用。在这里，我们表明，除了在颖片和外稃表皮细胞分化中的基本作用外，OsCR4 还正向调控水稻茎伸长，类似于玉米 CR4。尽管 OsCR4 是一种活性激酶，与玉米中的 CR4 和拟南芥中的 ACR4 相似，但 OsCR4 中保守的氨基酸 K532 对于其体外激酶活性并非必需。其他保守氨基酸是否需要其激酶活性，以及其在植物发育中的活性与功能之间的关系仍有待研究。
