Abstract：
: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.

杂志文章,评审abstract：:Polyploidy, or whole-genome duplication (WGD), is a ubiquitous feature of plant genomes, contributing to variation in both genome size and gene content. Although polyploidy has occurred in all major clades of land plants, it is most frequent in angiosperms. Following a WGD in the common ancestor of all extant angiospe...
