Plants in most natural habitats are exposed to a continuously changing environment, including fluctuating temperatures. Temperature variations can trigger acclimation or tolerance responses, depending on the severity of the signal. To guarantee food security under a changing climate, we need to fully understand how temperature response and tolerance are triggered and regulated. Here, we put forward the concept that responsiveness to temperature should be viewed in the context of dose-dependency. We discuss physiological, developmental, and molecular examples, predominantly from the model plant Arabidopsis thaliana, illustrating monophasic signaling responses across the physiological temperature gradient.
在大多数自然栖息地中,植物会暴露在不断变化的环境中,包括温度波动。温度变化可以根据信号的严重程度触发适应或耐受反应。为了在气候变化下保证粮食安全,我们需要充分了解温度响应和耐受是如何被触发和调节的。在这里,我们提出了这样一种观点,即应该根据剂量相关性来观察对温度的响应性。我们讨论了主要来自模式植物拟南芥的生理、发育和分子方面的例子,说明了在整个生理温度梯度上的单峰信号响应。
