Asymmetric cell divisions are essential to generate different cellular lineages. In plants, asymmetric cell divisions regulate the correct formation of the embryo, stomatal cells, apical and root meristems, and lateral roots. Current knowledge of regulation of asymmetric cell divisions suggests that, in addition to the function of key transcription factor networks, epigenetic mechanisms play crucial roles. Therefore, we highlight the importance of epigenetic regulation and chromatin dynamics for integration of signals and specification of cells that undergo asymmetric cell divisions, as well as for cell maintenance and cell fate establishment of both progenitor and daughter cells. We also discuss the polarization and segregation of cell components to ensure correct epigenetic memory or resetting of epigenetic marks during asymmetric cell divisions.

揭示表观遗传调控在植物发育过程中不对称细胞分裂中的作用

不对称细胞分裂对于产生不同的细胞谱系至关重要。在植物中，不对称的细胞分裂调节胚胎、气孔细胞、顶端和根分生组织以及侧根的正确形成。目前关于不对称细胞分裂调控的知识表明，除了关键转录因子网络的功能外，表观遗传机制也起着至关重要的作用。因此，我们强调表观遗传调控和染色质动力学对于整合信号和规范经历不对称细胞分裂的细胞以及祖细胞和子细胞的细胞维持和细胞命运建立的重要性。我们还讨论了细胞成分的极化和分离，以确保在不对称细胞分裂期间正确的表观遗传记忆或重置表观遗传标记。
