Modeling plant morphogenesis and growth

Show Summary Details

Preview

Plant development occurs through a carefully controlled interaction between cell differentiation and growth. Biochemical substances such as genes, proteins, and signalling molecules cause cells to differentiate into specialized tissues and regulate the growth that ultimately determines the emergent forms seen in plants. Thus in order to simulate plant morphogenesis, it is necessary to combine biochemical and genetic network simulations with models of plant growth. In the simplest case, growth can be specified descriptively, for example when exploring the biochemical aspect of patterning processes such as plant organ positioning or phyllotaxis. In cases where the shape is an emergent property of the model, physically-based growth models are preferred, which allow the simulation of interactions and feedbacks between biochemical processes and biomechanics.
