Herbicide Resistance in Plants

By P. Anderson, K. A. Hibberd. 2020

396 citations recorded by the source corpus.

This invention is directed to the production of plants, plant tissues and plant seeds which are resistant to inhibition by an herbicide which normally inhibits the growth and development of those plants, plant tissues and plant seeds. In particular this invention is directed to altered acetohydroxyacid synthase enzymes which are resistant to inhibition by herbicides which normally inhibit the activity of the synthase before such alteration. This invention further relates to genes encoding such enzymes, and to processes for utilizing these novel genes and enzymes. Further products of the invention include plants, plant tissues and seeds which exhibit resistance to such herbicides resulting from expression of genes encoding herbicide resistant acetohydroxyacid synthase enzyme.

• Evolution in action: plants resistant to herbicides. (2010, background): “Herbicide resistance in general is reviewed in several books (15, 35, 54, 83, 131, 134).”
• Lessons Learned From the History of Herbicide Resistance (2014, background): “However, there were concerns raised about the future evolution of herbicide resistant weed populations and an international conference was held from which came the first book on herbicide resistance edited by Lebaron and Gressel (1982).”
• The foxtail (Setaria) species-group (2003, background): “Although triazine-resistant (R) biotypes of many species have been shown to have reduced seed yield relative to susceptible variants (LeBaron and Gressel 1982), it is not clear that this reduction in growth and yield occurs in R biotypes of green foxtail (Ricroch et al. 1987).”
• Natural selection for resistance to the allelopathic effects of invasive plants (2005, background): “Resistance in plants evolves rapidly in response to man-made chemical herbicides (Powles & Holtum 1994), and plants can apparently adapt rapidly to the particular chemical composition of neighbouring plants (Ehlers & Thompson 2004).”
• Strategies for Using Transgenes to Produce Allelopathic Crops1 (2001, background): “With synthetic herbicides, evolution of resistance is much more rapid with certain molecular target sites (e.g., acetolactate synthase: Saari and Maxwell 1997) than to those with other sites of action (e.g., EPSP synthase: Dyer 1994).”
• Sustainability and Stewardship of Glyphosate and Glyphosate-resistant Crops (2007, background): “Consistent with this concept, mutations in the herbicide-binding site for D1 come with a fitness penalty, as expected for highly conserved amino acids (Powles and Holtum 1994).”
