In planta analysis of the mode of action of cinmethylin and confirmation of fatty acyl-ACP thioesterases (FATs) as primary site of action.

BACKGROUND Resistances to most known herbicide modes of action have emerged in many weeds, highlighting the need for new modes and sites of action. Cinmethylin, a selective herbicide effective against multi-resistant populations of Alopecurus myosuroides, Lolium rigidum, Lolium multiflorum and Apera spica-venti in whea...

Fendioxypyracil Exhibits Potent Inhibition of PPO-Resistant Mutant Enzymes and Robust Activity Against PPO-Resistant Amaranthus

Novel amino acid substitutions in Protoporphyrinogen oxidase 1 endow resistance to PPO-inhibiting herbicides in Bassia scoparia

PPO-inhibiting herbicides are widely used to manage weeds in different cropping systems, yet resistance evolution threatens their long-term efficacy. Here, we investigated the molecular basis of resistance to PPO-inhibiting herbicides in Bassia scoparia biotypes collected from four locations in North Dakota, USA. Green...

Characterization of a novel R98Q mutation that confers resistance to sulfentrazone in common ragweed (Ambrosia artemisiifolia) populations from Michigan

This study reports the first field occurrence of the R98Q substitution in PPO2 of A. artemisiifolia populations and demonstrates its association with to PPO inhibitor resistance, highlighting the rapid evolution of target-site resistance.
