Non-target-site resistance to ALS inhibitors in waterhemp
… amino acid biosynthesis, and is the target site of five families of herbicides referred to as ALS inhibitors. Waterhemp (Amaranthus tuberculatus) is considered one of the most problematic weeds in the Midwest cropping region. The evolution of herbicide resistance and multiple …

Exploiting muscarinic acetylcholine receptors as an insecticidal target to enhance the toxicity of gamma-amino butyric acid channel blockers and the continued challenges with resistance
… there are no commercialized insecticides targeting insect mAChRs. In this dissertation, effective target-site synergism was demonstrated in susceptible Drosophila melanogaster where mAChR agonism by pilocarpine enhanced the toxicity of insecticides targeting gamma-aminobutyric acid …

From the simple to the complex: an examination of different herbicide resistances
… as goosegrass (Eleusine indica), frequently have target-site resistance mechanisms controlled by a single gene. Outcrossing species, such as waterhemp (Amaranthus tuberculatus), in addition to having herbicide resistance conferred by a target-site mutation controlled by a single gene, often evolve …

Reduced Chemical Weed Control Options in Virginia for Corn and Turfgrass and Characterization of Sorghum halepense Expressing Multiple Resistance to Nicosulfuron and Glyphosate
… Herbicide resistance was not conferred via target-site mutation. Five ALS-gene site mutations were confirmed absent in Virginia johnsongrass, while three others were located in coding regions that could not be elucidated in johnsongrass. Further investigations showed glyphosate resistance …

Examination of target-site-based mechanisms of glyphosate resistance in waterhemp (Amaranthus tuberculatus)
… resistance to herbicides spanning multiple sites of action. Three potential mechanisms of resistance have been linked with GR waterhemp: EPSPS gene amplification, EPSPS target-site mutations, and reduced translocation. The objective of this research was to investigate the target-site-based …
