On growth and form of plant cells and tissues

By Professor Henrik Jönsson, Associate Director, University of Cambridge, UK (hosted by Dr. Timothy Saunders)

Plant cell growth is assumed to be a turgor driven process where the rigid cell walls yield and expand irreversibly. Since there is no cell migration, cell and tissue morphogenesis depends on regulation of the mechanics of the cell walls both heterogeneously and anisotropically. I will discuss how different shapes are formed in plants using models where anisotropy in mechanical stress and strain influences material anisotropy and heterogeneity in molecular concentrations influences material heterogeneity. I will further show how this relate to data on plant hormones and cytoskeletal dynamics.
