成体植物的基本形体是在胚胎发生时形成的，从而形成幼苗的幼体形态。拟南芥胚胎发生以高度规则的细胞分裂模式为特征。其中一些分裂是不对称的，产生具有不同命运的子细胞。然而，它们随后的分化可能仍然依赖于细胞间的通讯来完全完成或维持。在某些情况下，细胞命运规范仅仅依赖于细胞间的通信，这种通信通常在胚胎内位置信息的产生中起着重要作用。尽管生长素依赖的信号传导受到了广泛的关注，但其他的细胞间通讯方式也已被证实或提出。本文综述了拟南芥胚发生至球状中期的模式形成和细胞间通讯等方面的研究进展。
The basic body plan of the adult plant is established during embryogenesis, resulting in the juvenile form of the seedling. Arabidopsis embryogenesis is distinguished by a highly regular pattern of cell divisions. Some of these divisions are asymmetric, generating daughter cells with different fates. However, their subsequent differentiation might still depend on cell–cell communication to be fully accomplished or maintained. In some cases, cell fate specification solely depends on cell–cell communication that in general plays an important role in the generation of positional information within the embryo. Although auxin-dependent signalling has received much attention, other ways of cell–cell communication have also been demonstrated or suggested. This review focuses on aspects of pattern formation and cell–cell communication during Arabidopsis embryogenesis up to the mid-globular stage of development.
