- Abstract
- Understanding the relationship between epidermal outer cell wall structures and mechanical stress is needed to link plant biomechanics and stress distribution within tissues.With a modelling approach that consisted of constructing various 2D epidermal cell networks, and changing the mechanical properties of cell wall elements, we conducted a global sensitivity analysis on these anatomical Gmsh meshes. We used the Finite Element Method from the Fenics library to assess the proportional influence of the different mechanical properties of the cuticle, the inner and outer cell walls, and the middle lamella, as well as the turgor pressure. Our observations revealed the significance of cell geometry, turgor pressure, and proportional differences in mechanical properties between cell wall elements. These factors play a critical role in determining the localization of mechanical stress within this anatomical arrangement. By altering mechanical properties systematically, our study provides novel insights into the localization of mechanical stress within plant tissues, offering implications for biomechanics and potential applications in understanding plant responses to stretching forces.
