Pattern formation in embryogenesis generates the basic body plan of flowering plants by establishing the diversity of position-dependent cell fates characteristic of the seedling. The concept of pattern formation, which was originally based on the analysis of Arabidopsis pattern mutants, is re-examined in the light of recent data that address the origin of the axis of polarity, the origin of the primary meristems as elements of the apical-basal pattern and the formation of the radial pattern of tissue layers. The available evidence from genetic, molecular and experimental approaches supports the notion that embryonic pattern formation occurs in steps involving communication between clonally unrelated cells.
胚胎发育中的模式形成通过确立与位置相关的细胞命运多样性，从而产生开花植物的基本身体结构，这种多样性是幼苗所特有的。模式形成的概念最初基于对拟南芥模式突变体的分析，鉴于最近有关极性轴起源、作为顶基模式元件的初生分生组织起源以及组织层径向模式形成的数据，该概念被重新审视。来自遗传学、分子学和实验方法的现有证据支持这样一种观点，即胚胎模式形成是在涉及克隆无关细胞之间通讯的步骤中发生的。
