Plants are highly sensitive to temperature, and climate change is predicted to have negative impacts on agricultural productivity. Warming temperatures, coupled with a growing population, present a substantial challenge for food security and motivate research to understand how plants sense and respond to changes in temperature. Here, we synthesize our current understanding of temperature sensing and response in plants. We outline how temperature cues are integrated into preexisting signaling cascades using inherently temperature-sensitive proteins or processes. This dispersed nature of thermo-sensitive proteins and processes makes distinct signaling cascades sensitive to temperature. This model integrates current knowledge and distinguishes thermosensing from other conventional sensing and signaling mechanisms in plants.
植物对温度高度敏感，预计气候变化将对农业生产力产生负面影响。气温上升，再加上人口增长，对粮食安全构成了重大挑战，并促使人们开展研究，以了解植物如何感知温度变化并做出反应。在此，我们综合了目前对植物温度感知与反应的理解。我们概述了温度信号是如何利用内在的温度敏感蛋白或过程，整合到现有的信号级联反应中的。这种热敏蛋白和过程的分散性质，使得不同的信号级联反应对温度敏感。该模型整合了当前的知识，并将温度感知与植物中其他传统的感知和信号传导机制区分开来。
