Brad Binder, with collaborator Nicolas Papon at the University of Angers in France, published a Forum article in Trends in Microbiology. The article, An Evolutionary Perspective on Ethylene Sensing in Microorganisms, briefly highlights recent research showing that ethylene receptors are wide-spread in microorganisms including a few non-plant eukaryotes. Unlike in plants, these receptors have diverse domain structures suggesting some may have multiple inputs and diverse output mechanisms. A challenge for the future is to determine the roles of these receptors. To date, only one ethylene receptor has been characterized in a non-plant species. This was research conducted by former BCMB graduate student Randy Lacey in the Binder lab.
