The Arabidopsis root, with its ordered cell divisons and straightforward patterning, is a tractable model for understanding organ formation during plant development. Regular cell divisions in the root tip produce consistent cell type arrangements that can be followed through time. Root development occurs through the precise spatiotemporal control of transcription factors and phytohormone signaling networks. In this article, we provide a broad overview of the major events controlling embryonic and post-embryonic development within each major tissue and cell type in the primary root of Arabidopsis.
拟南芥根具有有序的细胞分裂和简单直接的模式，是理解植物发育过程中器官形成的一个易于处理的模型。根尖的正常细胞分裂产生一致的细胞类型排列，这些排列随时间推移是可以追踪的。根的发育通过转录因子和植物激素信号网络的精确时空控制来实现。在本文中，我们对拟南芥初生根中每个主要组织和细胞类型内控制胚胎发育和胚后发育的主要事件进行了广泛概述。
