Root development

To understand development it is useful to analyze simple systems. Because of the simplicity of its organization, the Arabidopsis root is one of the most tractable systems for the study of plant organogenesis. Using primarily molecular genetic approaches, rapid progress has been made in identifying some of the pathways regulating root development. Over the past 10 years, control of radial patterning, specification of epidermal cell types and placement of the root organizing center have begun to be elucidated.
