Abstract：
Plant growth is intimately linked to the availability of carbon and energy status. The Target of rapamycin (TOR) pathway is a highly relevant metabolic sensor and integrator of plant-assimilated C into development and growth. The cell wall accounts for around a third of the cell biomass, and the investment of C into this structure should be finely tuned for optimal growth. The plant C status plays a significant role in controlling the rate of cell wall synthesis. TOR signaling regulates cell growth and expansion, which are fundamental processes for plant development. The availability of nutrients and energy, sensed and integrated by TOR, influences cell division and elongation, ultimately impacting the synthesis and deposition of cell wall components. The plant cell wall is crucial in environmental adaptation and stress responses. TOR senses and internalizes various environmental cues, such as nutrient availability and stresses. These environmental factors influence TOR activity, which modulates cell wall remodeling to cope with changing conditions. Plant hormones, including auxins, gibberellins, and brassinosteroids, also regulate TOR signaling and cell wall-related processes. The connection between nutrients and cell wall pathways modulated by TOR are discussed.
摘要：
植物生长与碳和能源状况的可用性密切相关。雷帕霉素靶（TOR）途径是植物同化C发育和生长的高度相关的代谢传感器和整合器。细胞壁约占细胞生物量的三分之一，C对这种结构的投资应该进行微调，以实现最佳增长。植物C状态在控制细胞壁合成速率中起着重要作用。TOR信号调节细胞生长和扩增，这是植物发育的基本过程。营养和能量的可用性，由TOR感知和集成，影响细胞分裂和伸长，最终影响细胞壁成分的合成和沉积。植物细胞壁在环境适应和胁迫响应中至关重要。TOR感知和内化各种环境线索，比如营养供应和压力。这些环境因素影响TOR活性，它调节细胞壁重塑以应对不断变化的条件。植物激素,包括生长素,赤霉素,和油菜素类固醇,还调节TOR信号传导和细胞壁相关过程。讨论了营养素与TOR调节的细胞壁途径之间的联系。
