Engineering plant chronobiology for climate adaptation

We study and engineer the plant circadian clock, a molecular oscillator that allows plants to tell the time and adapt to seasonal environmental changes.

Accurately telling the time and predicting when the next day will begin is a matter of life and death for plants. As living beings that photosynthesise in the day and respire at night, most plants need to partition their most important metabolic functions temporally. In fact, an estimated 30% of gene expression in plants is controlled by their internal circadian clock.

Our lab aims to develop a sophisticated understanding of how the plant circadian clock controls all aspects of plant growth at the molecular level. We are also interested in how plants utilise the clock and other processes to help adapt to new geographic environments, something of paramount importance in a world experiencing accelerating climate change.
