Circadian rhythms are biological cycles with a period of about 24 h that persist in the absence of external cues. These rhythms are thought to provide a biological measure of the time of day. Circadian regulation has an incredibly pervasive influence upon plant life, regulating processes including photosynthesis, metabolism, growth, responses to environmental cues. Therefore, circadian regulation impacts traits of agricultural and ecological importance. My lab investigates signal transduction processes that participate in circadian regulation in plants. I will discuss work in my lab focusing on the integration of circadian timing cues with other types of environmental signals to regulate plant physiology, and aspects of the circadian regulation of signalling and metabolism of potential importance for agriculture.
