Summary We tested the hypothesis that the circadian clock modulates Ca2+‐based signalling pathways, using low‐temperature (LT)‐induced Ca2+ signals. We investigated the relationship between diurnal and circadian modulation of LT‐induced increases in cytosolic‐free calcium ([Ca2+]cyt), and regulation...
