This study evaluates fendioxypyracil's efficacy against PPO-resistant Amaranthus mutants and finds it maintains low IC50 values and strong weed control in field trials.

This study analyzes glutamine synthetase mutations in GFA-resistant plants, finding that G255D reduces enzyme activity but confers GFA insensitivity, while other mutations impair catalytic function.

The paper identifies a novel extrachromosomal circular DNA in Amaranthus palmeri that confers resistance to both glyphosate and glufosinate by co-duplicating resistance genes.
