摘要
细胞大小影响许多过程,包括营养物质和外部信号交换、细胞分裂和组织力学。在真核生物中,细胞进化出了评估自身大小的机制,为细胞周期进展或基因表达等过程提供信息。在此,我们回顾了了解植物细胞大小调控及其影响的最新进展,并将这些发现与其他真核生物的工作联系起来。重点包括利用 DNA 含量作为参考点来控制嫩枝分生组织中的细胞周期、气孔发育过程中的细胞命运决定取决于细胞大小,以及对倍性、细胞大小和细胞壁力学之间相互联系的认识。
Plant cell size: Links to cell cycle, differentiation and ploidy
Cell size affects many processes, including exchange of nutrients and external signals, cell division and tissue mechanics. Across eukaryotes, cells have evolved mechanisms that assess their own size to inform processes such as cell cycle progression or gene expression. Here, we review recent progress in understanding plant cell size regulation and its implications, relating these findings to work in other eukaryotes. Highlights include use of DNA contents as reference point to control the cell cycle in shoot meristems, a size-dependent cell fate decision during stomatal development and insights into the interconnection between ploidy, cell size and cell wall mechanics.
