Lateral roots (LRs) are crucial for increasing the surface area of root systems to explore heterogeneous soil environments. Major advances have recently been made in the model plant arabidopsis (Arabidopsis thaliana) to elucidate the cellular basis of LR development and the underlying gene regulatory networks (GRNs) that control the morphogenesis of the new root organ. This has provided a foundation for understanding the sophisticated adaptive mechanisms that regulate how plants pattern their root branching to match the spatial availability of resources such as water and nutrients in their external environment. We review new insights into the molecular, cellular, and environmental regulation of LR development in arabidopsis.
侧根（LRs）对于增加根系的表面积以探索异质土壤环境至关重要。最近，在模式植物拟南芥（Arabidopsis thaliana）中取得了重大进展，阐明了 LR 发育的细胞基础以及控制新根器官形态发生的基础基因调控网络（GRNs）。这为理解复杂的适应机制提供了基础，这些机制调节植物如何对其根分支进行模式化，以匹配其外部环境中水分和养分等资源的空间可用性。我们综述了拟南芥中 LR 发育的分子、细胞和环境调控的新见解。
