There is a growing interest in measuring the cell wall mechanical property at different locations in single walled cells. We present an inference scheme that maps relative surface elastic modulus distributions along the cell wall based on tracking the location of material marker points along the turgid and relaxed cell wall outline. A primary scheme is developed to provide a step-function inference of surface elastic moduli by computing the tensions and elastic stretches between material marker…

Molecular insights into the complex mechanics of plant epidermal cell walls
TLDR
A coarse-grained model based on polymer physics that recapitulates aspects of assembly and tensile mechanics of epidermal cell walls is developed and reveals design principles of biomaterials that combine stiffness with yielding and extensibility.
An Eulerian nonlinear elastic model for compressible and fluidic tissue with radially symmetric growth
TLDR
A mathematical model based on finite elasticity and growth theory and the reference map techniques to describe the coupled tissue growth and mechanics in the Eulerian frame is developed and applied to study tumor spheroid growth and epithelial disc growth when a reaction-diffusion process determines the growth-promoting factor field.
Inferring lateral tension distribution in wall structures of single cells
TLDR
An optimization method is developed that effectively restores the spatial resolution of the primary scheme by converting the discrete tension distributions to smooth polynomials and is applied to map tension distributions in moss protonemal cells.
Systematic mapping of cell wall mechanics in the regulation of cell morphogenesis
TLDR
A systematic method is introduced to map subcellular values of cell wall thickness and bulk elasticity in large populations of yeast cells with unprecedented accuracy and finds that lateral wall stiffness, defined by the surface modulus, σ = hY, robustly scales with cell diameter.
Cell wall architecture of Physcomitrella patens is revealed by atomic force microscopy
TLDR
Conventional staining and light microscopy were used to provide the first direct evidence that protonemal cells of P. patens lack a cuticle, and detailed surface structures identified by scanning electron microscopy (SEM).

TLDR
The primary walls of the cells of higher plants are made up of a framework of interwoven cellulose fibrils embedded in mostly amorphous substances which can be removed by various chemical treatments or by digestion with pectic enzymes.
