What is AHRI?


Welcome to The Australian Herbicide Resistance Initiative (AHRI) homepage! Before you dig into all our publications and podcasts, you might be wondering who we are and what we do. AHRI was a GRDC initiative which launched in 1998 under the guidance of Professor Stephen Powles. In 2018, we celebrated 20 years of GRDC funding, operating as a research group out of the University of Western Australia. You can get a great overview of what we’re all about by watching the video on the right. You can also learn more in this Outlooks on Pest Management article here.

Publications Aldo-keto reductase metabolizes glyphosate and confers glyphosate resistance in Echinochloa colona

Mon, 4 Nov 2019

In this Plant Physiology paper, it is clearly established that glyphosate resistance in this Echinochloa population is due to an enhanced capacity to metabolise glyphosate, catalysed by an Aldo-keto reductase gene.  The first author on the paper is Dr Pan Lang, now at the Hunan Agricultural University, Changsha, China. Pan Lang spent one year in our AHRI laboratory on a China Scholarship Council award and he continued this research upon his return to China.
