A systems approach to understand shoot branching
Shoots are ramifying systems with regular initiation of new growth axils called shoot branches. In seedplants, shoot buds initiate in leaf axils from axillary meristems (AMs) containing stem cells. The activitiesof AMs and buds play vital roles in plant architecture and crop yield. Whereas recent years have witnessedenormous progress the control of bud outgrowth, our knowledge of AM initiation remains rudimentary.Recently, systems biology approaches have been employed to study AM initiation, and have substantiallyexpanded our understanding of the underlying gene regulatory network (GRN). Systems approachesuncovered transcriptional signatures, predicted cellular functions, and identified new regulators andregulatory relationships. Complementary molecular genetic studies support and extend findings fromsystems studies.
