The slow and irreversible changes in plant cell shape include the cytoplasmic control of cell wall yielding in response to turgor pressure and the genesis of intracellular trafficking routes to the cell cortex. However, we lack a clear understanding of how interactions between cytoskeletal arrays and endomembrane compartments influence the physical properties of the cell wall. Recent forward and chemical genetic screens and sophisticated imaging analyses are revealing novel intracellular compartments and cytoskeleton interactions that impact the patterns of cellulose synthesis at the plasma membrane. These baseline data on the growth behavior of cylindrical cells provide a useful framework to better understand cell type specific strategies to generate complex shapes.
植物细胞形状的缓慢和不可逆转的变化包括细胞质对膨压做出反应的细胞壁产生的控制，以及细胞内运输途径向细胞皮层的形成。然而，我们对于细胞骨架排列和内膜隔室之间的相互作用如何影响细胞壁的物理性质还缺乏清晰的认识。最近的正向和化学遗传筛选以及复杂的成像分析正在揭示新的细胞内隔室和细胞骨架相互作用，这些作用影响着细胞质膜上纤维素合成的模式。这些关于圆柱形细胞生长行为的基础数据为更好地理解产生复杂形状的细胞类型特异性策略提供了有用的框架。
