Understanding gene expression dynamics in the context of the time of day and temperature response is an important part of understanding plant thermotolerance in a changing climate. Performing "gating" experiments under constant conditions and light-dark cycles allows users to identify and dissect the contribution of the time of day and circadian clock to the dynamic nature of stress-responsive genes. Here, we describe the design of specific laboratory experiments in plants (Arabidopsis thaliana and bread wheat, Triticum aestivum) to investigate temporal responses to heat (1 h at 37 °C) or cold (3 h at 4 °C), and we include known marker genes that have circadian-gated responses to temperature changes.
