Non-Target-Site Resistance to Herbicides: Recent Developments

Plants, 2019
Non-target-site resistance (NTSR) to herbicides in weeds can be conferred as a result of the alteration of one or more physiological processes, including herbicide absorption, translocation, sequestration, and metabolism.

Coexistence of target-site and non-target-site mechanisms of glyphosate resistance in Amaranthus palmeri populations from Argentina

Acta Scientiarum. Agronomy, 2021
Amaranthus palmeri S. Waston is currently one of the most problematic weeds worldwide. Biotypes with resistance to herbicides such as glyphosate and ALS inhibitors are now present in almost all Argentinian cultivable areas.

Dinitroaniline Herbicide Resistance and Mechanisms in Weeds

Frontiers in Plant Science, 2021
Dinitroanilines are microtubule inhibitors, targeting tubulin proteins in plants and protists. Dinitroaniline herbicides, such as trifluralin, pendimethalin and oryzalin, have been used as pre-emergence herbicides for weed control for decades.

Repeated origins, widespread gene flow, and allelic interactions of target-site herbicide resistance mutations

eLife, 2022
Causal mutations and their frequency in agricultural fields are well-characterized for herbicide resistance. However, we still lack understanding of their evolutionary history: the extent of parallelism in the origins of target-site resistance (TSR), how

Non-triazine photosystem II inhibitors provide effective control of metabolic atrazine-resistant Amaranthus tuberculatus. [PDF]

Pest Manag Sci
Metabolism‐based atrazine‐resistant Amaranthus tuberculatus populations ACR and MCR exhibit little or no cross‐resistance to amicarbazone and metribuzin, suggesting that non‐halogenated Group 5 herbicides can be utilized to re‐establish effective control.

Analysis of glutamine synthetase target-site mutations and their role in endowing glufosinate-ammonium resistance. [PDF]

Pest Manag Sci
GS2.2 G255D mutation conferred enzyme‐level glufosinate insensitivity but no whole‐plant resistance, showing trade‐offs between catalytic function and herbicide binding and providing a baseline for future studies on target‐site glufosinate resistance.

Thirty years of glyphosate-resistant crops and weeds: Current situation and future prospects. [PDF]

Pest Manag Sci
Since 1996, when the first glyphosate‐resistant crop was commercialized and the first resistant weed was reported, resistance has expanded globally. This review analyzes emergence patterns across weed species, crops, regions, resistance mechanisms, and herbicides.

Herbicide Metabolic Resistance in Poaceae Plants via the GA-GID1/DELLA-DOF2-P450s Module. [PDF]

Adv Sci (Weinh)
Plant hormone signaling modulates herbicide resistance in Echinochloa crus‐galli. The GA–DELLA–DOF2 cascade directly activates P450 detoxification genes in two Poaceae species, uncovering a core mechanism of metabolic herbicide resistance. ABSTRACT Barnyard grass (Echinochloa crus‐galli) is one of the world's most important weeds, and the evolution of ...

Detection of Target-Site Herbicide Resistance in the Common Ragweed: Nucleotide Polymorphism Genotyping by Targeted Amplicon Sequencing

Diversity, 2021
Background: The spread of herbicide-resistance Ambrosia artemisiifolia threatens not only the production of agricultural crops, but also the composition of weed communities.

The Resistance Levels and Target-Site Based Resistance Mechanisms to Glyphosate in Eleusine indica from China

Agronomy, 2022
The Dongting and Poyang Lakes are the important rice growing areas, and the Bohai Rim and Loess Plateau are the main producing areas of apples in China, where glyphosate has been used continuously to control weeds including Eleusine.
