Abstract: Global warming is now a major trend, in which temperature stress due to abnormal climate occurs frequently, posing a great challenge to the high-yield and stable agricultural production. The circadian clock, an endogenous, heritable timekeeping mechanism, endows plants with the ability to anticipate and respond rapidly to cyclic changes in external factors, which ensures that physiological and biochemical pathways are synchronized with the environment and greatly enhances plant's ability to survive and reproduce. The temperature responses and temperature compensation are not only related to the key scientific issue of "synchronization" of the circadian clock with environmental signals, but also to the application of crop adaptation to temperature stress in agriculture. Temperature compensation refers to the fact that within a broad range of physiological temperatures, through transcriptional and post-transcriptional architecture, the clock can essentially maintain the circadian period length unchanged, ensuring that the timekeeping mechanism operates accurately. Light, temperature and humidity are closely coupled in the natural environment, and they act as timing factors, transmitting external cues to the core oscillators via the input pathway, which affects almost all processes of plant growth and development. In this review, we summarized the historical research of the temperature response and compensation mechanism of plant circadian clocks, and describe the latest research progress, and also look forward to its application in crop genetic breeding, field management, etc. We seek to provide a novel idea and solution to the problem of temperature stress adaptation in crops.
