Heping’s research investigates resistance mechanisms with an emphasis on metabolism-based herbicide resistance in field-evolved resistant weed populations. Enhanced rates of herbicide metabolism are often catalysed by cytochrome P450 and other genes in many weeds. Heping now works on an ARC linkage project (in collaboration with Bayer Crop Science) to work on herbicide-metabolising gene discovery, characterisation and marker development which will greatly contribute to sustainable weed control.
