This study identifies a novel R98Q mutation in PPO2 conferring resistance to sulfentrazone in common ragweed populations from Michigan.

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 evaluates the potential for target-site resistance to the herbicide cinmethylin by analyzing amino acid substitutions in FAT A and FAT B, finding limited practical risk of resistance evolution.

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.

This study identifies PPO1 mutations in Bassia scoparia that confer resistance to PPO-inhibiting herbicides, with fomesafen remaining effective against resistant biotypes.

The paper investigates how extrachromosomal DNA (eccDNA) contributes to glufosinate resistance in Palmer amaranth by amplifying the GS2 gene.

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

The paper outlines genomic resources developed by the International Weed Genomics Consortium to improve weed control and crop breeding through insights into stress tolerance.

The paper investigates whether double PPO mutations can co-occur in the same allele and assesses their functionality in Amaranthus species.
