Agronomy, 2023 A study was carried out to determine the ALS (acetolactate synthase)-inhibitor herbicide resistance in the Mexican grass Ixophorus unisetus, a troublesome weed in corn crops in Mexico. First, the resistance was confirmed in field screening assays.

Reference genes to study herbicide stress response in Lolium sp.: up-regulation of P450 genes in plants resistant to acetolactate-synthase inhibitors. [PDF]
PLoS ONE, 2013 Variation in the expression of numerous genes is at the basis of plant response to environmental stresses. Non-target-site-based resistance to herbicides (NTSR), the major threat to grass weed chemical control, is governed by a subset of the genes ...

Genetic Mechanism of Non-Targeted-Site Resistance to Diquat in Spirodela polyrhiza
PlantsUnderstanding non-target-site resistance (NTSR) to herbicides represents a pressing challenge as NTSR is widespread in many weeds. Using giant duckweed (Spirodela polyrhiza) as a model, we systematically investigated genetic and molecular mechanisms of ...

Mechanism of Resistance to S-metolachlor in Palmer amaranth
Frontiers in Plant Science, 2021 Herbicides are major tools for effective weed management. The evolution of resistance to herbicides in weedy species, especially contributed by non-target-site-based resistance (NTSR) is a worrisome issue in crop production globally. Glyphosate-resistant

Julius-Kühn-Archiv, 2014 Blackgrass (Alopecurus myosuroides) is one of the most economically important weeds in Europe. Because of the development and distribution of herbicide resistant populations the control of this weed has become a serious challenge in agriculture.

Pest Management Science, EarlyView.Over a decade, Arkansas Amaranthus palmeri populations maintained resistance to PPO‐inhibiting herbicides. PPO2 mutations relate to shifts in herbicide resistance patterns over time. Abstract BACKGROUND Amaranthus is a highly troublesome weed genera globally.

Agronomy, 2020 In this work, we studied the effect of three glyphosate formulations (isopropylamine, ammonium and potassium salts) and two non-ionic adjuvants on the resistance response of two resistant (R1, R2) and one susceptible population of the highly invasive ...

Pest Management Science, EarlyView.This review bridges the gap between understanding resistance mechanisms and applying them in weed management, highlighting how mechanistic insights reveal vulnerabilities that can guide more effective control strategies. Abstract Herbicide resistance remains one of the most intensively studied areas in weed science because of its direct consequences ...

Pest Management Science, EarlyView.Using cellular phenotyping and resistance profiling, we show that herbicides across the Herbicide Resistance Action Committee (HRAC) Groups 3 and 23 induce indistinguishable, dose‐dependent microtubule defects. Resistance patterns, rather than cellular phenotypes, reveal distinct sites of action and support reclassifying Group 3 as α‐tubulin binders ...
