枝条是分枝系统，有规律地启动称为枝条的新的生长腋芽。在种子植物中，芽从含有干细胞的腋生分生组织(AM)中萌发。AM和芽的活动对植物结构和作物产量起着至关重要的作用。虽然近年来在控制芽生长方面取得了巨大的进展，但我们对AM启动的了解仍然很初级。最近，系统生物学方法被用来研究AM的启动，并极大地扩展了我们对潜在的基因调控网络(GRN)的理解。系统方法发现了转录签名，预测了细胞功能，并确定了新的调节器和调节关系。互补的分子遗传学研究支持并扩展了系统研究的结果。
Shoots are ramifying systems with regular initiation of new growth axils called shoot branches. In seed plants, shoot buds initiate in leaf axils from axillary meristems (AMs) containing stem cells. The activities of AMs and buds play vital roles in plant architecture and crop yield. Whereas recent years have witnessed enormous 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 substantially expanded our understanding of the underlying gene regulatory network (GRN). Systems approaches uncovered transcriptional signatures, predicted cellular functions, and identified new regulators and regulatory relationships. Complementary molecular genetic studies support and extend findings from systems studies.
