| Outline of Final Research Achievements |
We investigated the mechanism of the formation of the jigsaw puzzle-like morphology in pavement cells in dicotyledonous plants by using a mathematical model. We developed the mathematical model that considers the balance between cell and cell wall growth, restricted global cell growth orientation, and regulation of local cell outgrowth mediated by a Rho-like GTPase-cytoskeleton system. Our computational simulations suggest that interdigitated patterns form because of mechanical buckling in the absence of Rho-like GTPase-dependent regulation of local cell outgrowth. Our model clarifies the cell wall mechanics influencing pavement cell morphogenesis.
