How cells acquire their identities and grow coordinately within a tissue is a fundamental question to understand plant development. In angiosperms, the shoot apical meristem (SAM) is a multicellular tissue containing a stem cell niche, which activity allows for a dynamic equilibrium between maintenance of stem cells and production of differentiated cells that are incorporated in new aerial tissues and lateral organs produced in the SAM. Plant hormones are small-molecule signals controlling many aspects of plant development and physiology. Several hormones are essential regulators of SAM activities. This review highlights current advances that are starting to decipher the complex mechanisms underlying the hormonal control of cell identity and growth in the SAM.

茎尖分生组织细胞特性和生长的激素控制

细胞如何获得它们的身份并在组织内协调生长是理解植物发育的一个基本问题。在被子植物中,茎尖分生组织 (SAM) 是一种包含干细胞生态位的多细胞组织,其活性允许在干细胞的维持和分化细胞的产生之间实现动态平衡,这些分化细胞并入新的气生组织和侧向器官中产生的器官。山姆。植物激素是控制植物发育和生理的许多方面的小分子信号。几种激素是 SAM 活动的重要调节剂。这篇综述强调了当前的进展,这些进展开始破译 SAM 中激素控制细胞特性和生长的复杂机制。
