Early embryonic development in the flowering plant Arabidopsis thaliana follows a predictable sequence of cell divisions. Anatomical hallmarks and the expression of marker genes in dynamic patterns indicate that new cell fates are established with virtually every round of mitosis. Although some of the factors regulating these early patterning events have been identified, the overall process remains relatively poorly understood. Starting at the globular stage, when the embryo has approximately 100 cells, the organization of development appears to be taken over by programs that regulate postembryonic patterning throughout the life cycle.

拟南芥的胚胎模式。

开花植物拟南芥的早期胚胎发育遵循可预测的细胞分裂序列。解剖学特征和动态模式中标记基因的表达表明，几乎每轮有丝分裂都建立了新的细胞命运。尽管已经确定了调节这些早期构图事件的一些因素，但是对整个过程仍知之甚少。从球状阶段开始，当胚胎大约有100个细胞时，发育的组织似乎被整个生命周期中调节胚胎后形态的程序所接管。
