不对称细胞分裂（ACD）用于在植物发育过程中创造生物体形式和细胞多样性。在几个胚胎和胚后环境中，已经确定了指定细胞命运的基因和提供位置信息的网络。然而，将这些信息转化为物理ACD的细胞机制仍然不清楚。在这篇综述中，我们研究细胞极化事件之前，在植物中的不对称分裂。使用来自其他生物体的研究和植物有丝分裂后极性产生的原则，我们奋进提供一个框架，什么是已知的，什么是在地平线上，什么是迫切需要发展一个严格的机械理解植物中的ACD。
Asymmetric cell divisions (ACDs) are used to create organismal form and cellular diversity during plant development. In several embryonic and postembryonic contexts, genes that specify cell fates and networks that provide positional information have been identified. The cellular mechanisms that translate this information into a physically ACD, however, are still obscure. In this review we examine the cell polarization events that precede asymmetric divisions in plants. Using principles derived from studies of other organisms and from postmitotic polarity generation in plants, we endeavor to provide a framework of what is known, what is on the horizon and what is critically needed to develop a rigorous mechanistic understanding of ACDs in plants.
