Herbicide selectivity in cereals and competing weeds

Selective herbicides enable the control of weeds without causing damage to the associated crop.  Cytochrome P450 enzymes (CYPs) are responsible for determining the metabolism and hence selectivity of many of the world’s most important herbicides. CYPs belong to a large gene family and little is known about which are the key CYPs involved in the metabolism of herbicides.  In a collaboration with Syngenta, the aim is to initiate an assay and expression platform capability around CYPs from crops and competing weeds, leading to insights into their role in herbicide selectivity and resistance.
