Similar and Yet Different: Oxygen Sensing in Animals and Plants

The ability to perceive oxygen levels and adapt metabolism on the basis of its availability is vital for most eukaryotic cells. Here, we retrace the key steps that led to the identification of oxygen-sensing mechanisms in animals and plants and compare the essential features of the two strategies.
