Plants exhibit enormous plasticity in regulating their architecture to be able to adapt to a constantly changing environment and carry out vital functions such as photosynthesis, anchoring, and nutrient uptake. Phytohormones play a role in regulating these responses, but sugar signalling mechanisms are also crucial. Sucrose is not only an important source of carbon and energy fuelling plant growth, but it also functions as a signalling molecule that influences various developmental processes. Trehalose 6-phosphate (Tre6P), a sucrose-specific signalling metabolite, is emerging as an important regulator in plant metabolism and development. Key players involved in sucrose and Tre6P signalling pathways, including MAX2, SnRK1, bZIP11, and TOR, have been implicated in processes such as flowering, branching, and root growth. We will summarize our current knowledge of how these pathways shape shoot and root architecture and highlight how sucrose and Tre6P signalling are integrated with known signalling networks in shaping plant growth.

植物在调节其结构方面表现出巨大的可塑性，能够适应不断变化的环境并执行光合作用、锚定和养分吸收等重要功能。植物激素在调节这些反应中发挥着作用，但糖信号传导机制也至关重要。蔗糖不仅是植物生长所需的碳和能量的重要来源，而且还充当影响各种发育过程的信号分子。海藻糖 6-磷酸 (Tre6P) 是一种蔗糖特异性信号代谢产物，正在成为植物代谢和发育的重要调节剂。参与蔗糖和 Tre6P信号通路的关键参与者，包括 MAX2、SnRK1、bZIP11 和 TOR，与开花、分枝和根生长等过程有关。我们将总结目前关于这些途径如何塑造芽和根结构的知识，并重点介绍蔗糖和 Tre6P 信号如何与已知的信号网络整合以塑造植物生长。
