Plants, as autotrophic organisms, capture light energy to convert carbon dioxide into ATP, NADPH, and sugars, which are essential for the biosynthesis of building blocks, cell proliferation, biomass accumulation, and reproductive fitness. The Target Of Rapamycin (TOR) signalling pathway is a master regulator in sensing energy and nutrients, adapting the metabolic network and cell behaviour in response to environmental resource availability. In the past years, exciting advances in this endeavour have pointed out this pathway's importance in controlling metabolic homeostasis in various biological processes and systems. In this review, we discuss these recent discoveries highlighting the need for a metabolic threshold for the proper function of this kinase complex at the cellular level and across distinct tissues and organs to control growth and development in plants.
植物作为自养生物，捕获光能以将二氧化碳转化为ATP、NADPH和糖类，这些对于生物合成构件、细胞增殖、生物量积累和繁殖适应性至关重要。雷帕霉素靶蛋白（TOR）信号通路是感知能量和营养物质、根据环境资源可用性调整代谢网络和细胞行为的主要调节因子。在过去几年中，这一研究领域取得了令人兴奋的进展，指出该通路在控制各种生物过程和系统中的代谢稳态方面具有重要意义。在本综述中，我们讨论了这些最新发现，强调了在细胞水平以及不同组织和器官中，为使该激酶复合物正常发挥功能以控制植物生长发育，需要一个代谢阈值。
