由於植物無法移動，因此演化出複雜的基因調控機制以應付環境變化。在氣候變化加劇的近代，植物如何適應已成為相當重要的研究課題。許多環境因子中，受溫室效應影響，逐漸上升的平均溫度和瞬間出現的高溫是比較受到關注的，本文回顧植物感受熱及熱逆境反應相關研究。基礎研究及調控模型目前仍以模式物種為主，而近年已有木本植物熱反應的研究報告。使用不同物種為材料的研究說明了熱休克蛋白功能有物種間不保守的情形，顯示在研究上不能過度依賴基因功能預測。

As sessile organisms, plants acquire sophisticated gene regulation mechanism through evolution to respond to changing environment. Due to intensified climate change, response of plants has been an important research topic. In many environmental factors, rising temperature and heat wave receive greater attention. This article discusses plant heat perception and heat stress response. Heat response regulation model is currently based on model plant, but there is an increasing research that uses woody plant as research material. Use of different materials among different research revealed that function of the genes participated in heat response cannot rely on prediction and more research is needed.
