Gene discovery for herbicide resistance

Genes drive herbicide resistance mechanisms

Understanding the mechanisms of resistance starts with assessing whether resistance is due to changes at the herbicide enzyme target site (target site resistance) or due to changes elsewhere in the plant (non-target site resistance). AHRI focuses on annual ryegrass and wild radish, but also researches wild oats and other weed species.

The Gene Discovery for Herbicide Resistance team is led by Principal Research Fellow Dr Qin Yu and Research Associate Dr Heping Han, with advice from Professor Stephen Powles. They investigate resistance mechanisms in current and new herbicide-resistant weed biotypes, using biochemical and molecular analysis.
