To control flowering and fruit ripening, plants release the gaseous hormone ethylene. Environmental conditions, including drought, salinity and pathogens, can also cause levels of the hormone to fluctuate. Therefore, monitoring ethylene’s release in real time could provide a farmer with important information about a plant’s development and health. Now, researchers reporting in ACS Central Science have developed an easy-to-use, robust sensor that can do just that.
