Organogenesis is the developmental process for producing new organs from undifferentiated cells. In plants, most organs are formed during postembryonic development. Shoot lateral organs are generated in the shoot apical meristem whereas lateral roots develop outside the root apical meristem. While lateral organ formation at the shoot and root might seem quite different, recent genetic studies have highlighted numerous parallels between these processes. In particular, the dynamic accumulation of auxin has been shown to play a crucial role both as a "morphogenetic trigger" and as a morphogen in both phenomena. This suggests that a unique model system could be adopted to study organogenesis in plants. In this chapter we describe the conceptual and technical advantages that support lateral root development as a good model system for studying organogenesis in plants. © Springer Science+Business Media New York 2013.
