Coupling water fluxes with cell wall mechanics in a multicellular model of plant development

Hierarchy of models presented in this article.
The cells are given a height h as illustrated in c). The walls that hold stresses (in green) have a thickness w. a) Lockhart-Ortega model: uniaxial growth in the x direction of a cell of length l. b) two cells extension, both growing along x; the lighter shade of green corresponds to a lower elastic modulus; c) 2D extension of a single cell growth; d) Multicellular, multidimensional model; left: fluxes, right: mechanical equilibrium; the stress σ is proportionnal to the elastic deformation εe; E is the elastic modulus.
