受体样激酶是植物生长的重要调节因子。通常一个受体参与调节多种组织中的多种发育过程。ERECTA家族（ERf）受体与气孔发育、地上器官伸长、茎尖分生组织功能、花分化和生物/非生物胁迫有关。在这里，我们探讨这些基因在胚胎发生过程中的作用。ERf在发育中的胚胎中表达，其中它们的表达逐渐限于胚胎的上半部分。在胚胎发育过程中，ERfs通过促进细胞增殖和抑制气孔的过早分化来刺激子叶的生长。(C)2014年欧洲生物化学学会联合会。Elsevier B. V.出版，保留所有权利。
Receptor-like kinases are important regulators of plant growth. Often a single receptor is involved in regulation of multiple developmental processes in a variety of tissues. ERECTA family (ERf) receptors have previously been linked with stomata development, above-ground organ elongation, shoot apical meristem function, flower differentiation and biotic/abiotic stresses. Here we explore the role of these genes during embryogenesis. ERfs are expressed in the developing embryo, where their expression is progressively limited to the upper half of the embryo. During embryogenesis ERfs redundantly stimulate the growth of cotyledons by promoting cell proliferation and inhibiting premature stomata differentiation.
