3-h pulses of elevated temperatures (30 degrees C, 35 degrees C, 40 degrees C) phase shift the circadian conidiation rhythm of Neurospora crassa. The phase and amplitude of the phase response curves (PRC) were measured in wild type (frq+) and frequency mutants (frq 1, frq 7). The dose dependence of the phase shifts was compared to the dose dependence of total protein synthesis inhibition and heat shock protein induction in the three strains. All processes showed an almost linear dependence on temperature. These experiments and other available data suggest that a temperature increase may act on the circadian rhythm by a process belonging to the heat shock response.
3小时的高温脉冲（30摄氏度、35摄氏度、40摄氏度）会使粗糙脉孢菌的昼夜产孢节律发生相移。在野生型（frq+）和频率突变体（frq 1、frq 7）中测量了相位响应曲线（PRC）的相位和振幅。比较了三个菌株中相移的剂量依赖性与总蛋白质合成抑制和热休克蛋白诱导的剂量依赖性。所有过程对温度均表现出几乎呈线性的依赖性。这些实验和其他现有数据表明，温度升高可能通过属于热休克反应的过程作用于昼夜节律。
