Integrated Molecular Circuits for Stem Cell Activity in Arabidopsis Roots
Pattern formation in biological systems has long been thought to emanate from hierarchical control systems. More recently, another view on the development of patterns has gained ground, where multilevel interactions (spanning molecular, cellular and organismal processes and allowing feedback between all levels) create different attractor states for the biological system. In moving towards attractor states, complicated patterns may ensue as an emergent property from simple interactions. We study these processes in plant development, because plant cells do not move relative to one another which facilitates analysis.
