摘　　要：高等植物分生组织中细胞由快速分裂向分化过渡是器官发育的一个关键步骤,其调控机理一直备受关注。本文简要介绍了在拟南芥根尖分生组织中目前提出的有关该步骤分子调控机理的几个假说,包括生长素-PLTs假说,生长素最小值假说和PLTs和ARRs双向抑制假说,以期为相关领域的研究者提供参考。The transition from rapid division to differentiation of cells in meristems is a key step in organogenesis of higher plants, and its regulatory mechanisms have always been a focus of research. This paper briefly introduces several hypotheses about the molecular regulation mechanism of this step in the Arabidopsis root apical meristem, including the auxin-PLTs hypothesis, auxin minimum hypothesis and PLTs and ARRs mutul inhibition hypothesis, with the aim of providing a reference for researchers in related fields.
