FORCE-ing the shape

The plant cell wall is a dynamic structure that mediates cell and organ morphogenesis and provides structural support to the whole plant body. The primary load bearing components of the cell wall are a cellulose-xyloglucan network embedded in a pectin matrix. Plant morphogenesis is regulated by a constant adjustment of the chemical structure and thus mechanical properties of the cell wall components. These modifications are modulated by a variety of different remodeling agents that precisely control cell wall mechanical properties. Here, we briefly review the major recent updates on cell wall mechanics during growth and development.
