Abstract

As sessile photoautotrophs, plants constantly encounter diverse environmental stresses. Recent research has focused on elucidating sugar and energy signaling mediated by hexokinase (HXK), sucrose non-fermenting 1-related protein kinase 1 (SnRK1), and the target of rapamycin (TOR) and assessing its intricate interplay with hormones and secondary metabolism. HXK serves as a pivotal regulator of glucose sensing and metabolism. It affects plant growth and development in response to nutrient availability. SnRK1 acts as a vital energy sensor that regulates metabolic adjustments during stress to bolster plant resilience. Moreover, TOR integrates nutrient signals to finely modulate growth and development, balancing cellular metabolism and resource allocation. Understanding the functions of HXK, SnRK1, and TOR can provide profound insights into plant adaptation mechanisms and open promising avenues for leveraging biotechnological strategies to enhance the stress tolerance and nutritional value of crops. This narrative review focuses on recent advancements in the molecular mechanisms of HXK, SnRK1, and TOR and explores their potential applications in agricultural biotechnology.

植物中的HXK， SnRK1和TOR信号：揭示胁迫反应和次生代谢机制。

作为无根的光自养生物，植物不断遭受各种环境胁迫。最近的研究主要集中在阐明己糖激酶（HXK）、蔗糖非发酵1相关蛋白激酶1 （SnRK1）和雷帕霉素（TOR）靶点介导的糖和能量信号，并评估其与激素和次级代谢的复杂相互作用。HXK是葡萄糖感知和代谢的关键调节因子。它通过对养分有效性的响应影响植物的生长发育。SnRK1作为一种重要的能量传感器，在逆境中调节代谢调节，增强植物的恢复力。此外，TOR整合营养信号，精细调节生长发育，平衡细胞代谢和资源分配。了解HXK、SnRK1和TOR的功能可以深入了解植物的适应机制，并为利用生物技术策略提高作物的抗逆性和营养价值开辟有希望的途径。本文综述了HXK、SnRK1和TOR的分子机制的最新进展，并探讨了它们在农业生物技术中的潜在应用。
