Root architecture is an important agronomic trait that plays an essential role in water uptake, soil compactions, nutrient recycling, plant-microbe interactions, and hormone-mediated signaling pathways. Recently, significant advancements have been made in understanding how the complex interactions of phytohormones regulate the dynamic organization of root architecture in crops. Moreover, phytohormones, particularly auxin, act as internal regulators of root development in soil, starting from the early organogenesis to the formation of root hair (RH) through diverse signaling mechanisms. However, a considerable gap remains in understanding the hormonal cross-talk during various developmental stages of roots. This review examines the dynamic aspects of phytohormone signaling, cross-talk mechanisms, and the activation of transcription factors (TFs) throughout various developmental stages of the root life cycle. Understanding these developmental processes, together with hormonal signaling and molecular engineering in crops, can improve our knowledge of root development under various environmental conditions.
根系结构是一种重要的农艺性状，在水分吸收、土壤压实、养分循环、植物-微生物相互作用以及激素介导的信号通路中发挥着至关重要的作用。最近，在理解植物激素的复杂相互作用如何调节作物根系结构的动态组织方面取得了重大进展。此外，植物激素，特别是生长素，作为土壤中根系发育的内部调节因子，从早期器官发生到根毛（RH）形成，通过多种信号机制发挥作用。然而，在理解根系不同发育阶段的激素相互作用方面仍存在相当大的差距。本综述研究了植物激素信号传导的动态方面、相互作用机制以及在根系生命周期的各个发育阶段转录因子（TFs）的激活。了解这些发育过程，以及作物中的激素信号传导和分子工程，可以提高我们对各种环境条件下根系发育的认识。
