Temperature is a key environmental cue that influences the distribution and behavior of plants globally. Understanding how plants sense temperature and integrate this information into their development is important to determine how plants adapt to climate change and to apply this knowledge to the breeding of climate-resilient crops. The mechanisms of temperature perception in eukaryotes are only just beginning to be understood, with multiple molecular phenomena with inherent temperature dependencies, such as RNA melting, phytochrome dark reversion, and protein phase change, being exploited by nature to create thermosensory signaling networks. Here, we review recent progress in understanding how temperature sensing in four major pathways in Arabidopsis thaliana occurs: vernalization, cold stress, thermomorphogenesis, and heat stress. We discuss outstanding questions in the field and the importance of these mechanisms in the context of breeding climate-resilient crops.

植物温度传感

温度是影响全球植物分布和行为的关键环境因素。了解植物如何感知温度并将这些信息整合到其发育中对于确定植物如何适应气候变化以及将这些知识应用于气候适应性作物的育种非常重要。真核生物的温度感知机制才刚刚开始被理解，多种具有固有温度依赖性的分子现象，例如RNA熔化、光敏色素暗回复和蛋白质相变，被大自然用来创建热感信号网络。在这里，我们回顾了了解拟南芥四个主要途径温度感知如何发生的最新进展：春化、冷应激、热形态发生和热应激。我们讨论了该领域的突出问题以及这些机制在培育气候适应型作物方面的重要性。
