About

Most organisms possess an internal timer or circadian clock that allows them to regulate their physiology to better adapt to our continually changing world. These circadian clocks generate roughly 24 hour rhythms in physiology and behavior that are maintained even in the absence of environmental cues. Although the molecular components of circadian clocks are not conserved across higher taxa, in all organisms studied these clocks are cell autonomous oscillators and in eukaryotes are composed of complex transcriptional networks.

The Harmer lab uses forward and reverse genetics, genomics, biochemistry, and physiological studies to better understand the nature of the plant clock and how it helps shape plant adaptations to ever-changing environments. We use techniques ranging from ‘omics approaches to field-based studies to better understand how the plant clock works and how it promotes fitness in the natural environment.
