植物细胞控制生长和形状的机制是许多事件协调作用的结果，特别是细胞壁应力松弛和turgor-driven膨胀。膨压的标量性质会驱使植物细胞呈现球形;然而，事实并非如此，因为植物细胞显示出惊人的多种形态。植物细胞壁是动态结构，其可以显示基质多糖组成和浓度的改变，这最终影响壁变形速率。植物细胞形状的广泛变化，从细长的圆柱体（如花粉管）和拼图般的表皮细胞，非常长的纤维和分支的星状叶毛，可以理解，如果潜在的机制调节壁生物合成和细胞骨架动力学解决。本文综述了植物细胞壁-细胞骨架系统连续体在植物细胞膨胀、生长和形态调控中的作用机制。特别是，我们讨论从分子的角度来看，具有显著不同的几何形状的细胞类型的特征的生长机制，并描述它们与初生壁的关系。在这里，目的是为读者提供植物细胞设法扩展和控制其最终形状的众多事件的全面概述。
The mechanisms through which plant cells control growth and shape are the result of the coordinated action of many events, notably cell wall stress relaxation and turgor-driven expansion. The scalar nature of turgor pressure would drive plant cells to assume spherical shapes; however, this is not the case, as plant cells show an amazing variety of morphologies. Plant cell walls are dynamic structures that can display alterations in matrix polysaccharide composition and concentration, which ultimately affect the wall deformation rate. The wide varieties of plant cell shapes, spanning from elongated cylinders (as pollen tubes) and jigsaw puzzle-like epidermal cells, to very long fibres and branched stellate leaf trichomes, can be understood if the underlying mechanisms regulating wall biosynthesis and cytoskeletal dynamics are addressed. This review aims at gathering the available knowledge on the fundamental mechanisms regulating expansion, growth and shape in plant cells by putting a special emphasis on the cell wall-cytoskeleton system continuum. In particular, we discuss from a molecular point of view the growth mechanisms characterizing cell types with strikingly different geometries and describe their relationship with primary walls. The purpose, here, is to provide the reader with a comprehensive overview of the multitude of events through which plant cells manage to expand and control their final shapes.
