dc.description.abstract | The relatively thick primary walls of epidermal and collenchyma cells often form waviness on the surface that faces
the protoplast when they are released from the tensile in-plane stress that operates in situ. This waviness is a manifestation
of buckling that results from the heterogeneity of the elastic strain across the wall. In this study, this heterogeneity
was confirmed by the spontaneous bending of isolated wall fragments that were initially flat. We combined the
empirical data on the formation of waviness in growing cell walls with computations of the buckled wall shapes. We
chose cylindrical-shaped organs with a high degree of longitudinal tissue stress because in such organs the surface
deformation that accompanies the removal of the stress is strongly anisotropic and leads to the formation of waviness
in which wrinkles on the inner wall surface are always transverse to the organ axis. The computations showed that the
strain heterogeneity results from individual or overlaid gradients of pre-stress and stiffness across the wall. The computed
wall shapes depend on the assumed wall thickness and mechanical gradients. Thus, a quantitative analysis of
the wall waviness that forms after stress removal can be used to assess the mechanical heterogeneity of the cell wall. | pl_PL |
