Plants are exposed to a wide range of temperatures during their life cycle and need to continuously adapt. These adaptations need to deal with temperature changes on a daily and seasonal level and with temperatures affected by climate change. Increasing global temperatures negatively impact crop performance, and several physiological, biochemical, morphological and developmental responses to increased temperature have been described that allow plants to mitigate this. In this review, we assess various growth, development, and yield-related responses of crops to extreme and moderate high temperature, focusing on knowledge gained from both monocot (e.g. wheat, barley, maize, rice) and dicot crops (e.g. soybean and tomato) and incorporating information from model plants (e.g. Arabidopsis and Brachypodium). This revealed common and different responses between dicot and monocot crops, and defined different temperature thresholds depending on the species, growth stage and organ.
植物在其生命周期中会经历广泛的温度范围，需要不断适应。这些适应需要应对每日和季节性的温度变化以及受气候变化影响的温度。全球气温上升对作物表现产生负面影响，并且已经描述了植物对温度升高的几种生理、生化、形态和发育反应，这些反应使植物能够减轻这种影响。在本综述中，我们评估了作物对极端和适度高温的各种生长、发育和产量相关反应，重点关注从单子叶作物（如小麦、大麦、玉米、水稻）和双子叶作物（如大豆和番茄）中获得的知识，并纳入来自模式植物（如拟南芥和短柄草）的信息。这揭示了双子叶和单子叶作物之间的共同和不同反应，并根据物种、生长阶段和器官定义了不同的温度阈值。
