Global climate change, characterized by increased frequency and intensity of extreme temperature events, poses significant challenges to plant survival and crop productivity. While considerable research has elucidated plant responses to temperature stress, the molecular mechanisms, particularly those involved in temperature sensing, remain incompletely understood. Thermosensors in plants play a crucial role in translating temperature signals into cellular responses, initiating the downstream signaling cascades that govern adaptive processes. This review highlights recent advances in the identification and classification of plant thermosensors, exploring their physiological roles and the biochemical mechanisms by which they sense temperature changes. We also address the challenges in thermosensor discovery and discuss emerging strategies to uncover novel thermosensory mechanisms, with implications for improving plant resilience to temperature stress in the face of a rapidly changing climate.
全球气候变化以极端温度事件的频率和强度增加为特征，对植物生存和作物生产力构成重大挑战。虽然大量研究已经阐明了植物对温度胁迫的反应，但分子机制，尤其是那些涉及温度感知的机制，仍未完全了解。植物中的温度感受器在将温度信号转化为细胞反应、启动控制适应性过程的下游信号级联反应中起着关键作用。本综述重点介绍了植物温度感受器识别和分类方面的最新进展，探讨了它们的生理作用以及感知温度变化的生化机制。我们还讨论了温度感受器发现方面的挑战，并探讨了揭示新型温度感知机制的新兴策略，这对于在快速变化的气候条件下提高植物对温度胁迫的恢复力具有重要意义。
