Eugenia brasiliensis: Analysis of the Chemical Profile and Evaluation of Cytotoxic Potential

open access: yesChemistry &Biodiversity, Volume 22, Issue 9, September 2025.
Leaves of Eugenia brasiliensis were dried, crushed and macerated with polarity increment. The antiporliferative and anti‐migratory potential and the cell cycle were evaluated. 28 compounds were tentatively identified by mass sceptrometry. ABSTRACT This work evaluated the antiproliferative potential of Eugenia brasiliensis leaf extracts against the HeLa

Carfentrazone-ethyl resistance in an Amaranthus tuberculatus population is not mediated by amino acid alterations in the PPO2 protein.

open access: yesPLoS ONE, 2019
To date, the only known mechanism conferring protoporphyrinogen IX oxidase (PPO)-inhibitor resistance in waterhemp (Amaranthus tuberculatus) is a glycine deletion in PPO2 (ΔG210), which results in cross-resistance to foliar PPO-inhibiting herbicides ...

Fitness of ALS-Inhibitors Herbicide Resistant Population of Loose Silky Bentgrass (Apera spica-venti)

open access: yesFrontiers in Plant Science, 2017
Herbicide resistance is an example of plant evolution caused by an increased reliance on herbicides with few sites of action to manage weed populations.

Natural variation of response to glyphosate in Sinapis alba (Brassicaceae): Physiological effects, shikimate accumulation and genetic mechanisms

open access: yesWeed Research, Volume 65, Issue 5, September/October 2025.
Abstract Glyphosate is the most widely used herbicide worldwide, and glyphosate‐resistant weeds have increased globally. Resistance mechanisms, including target‐site resistance (TSR) and non‐target‐site resistance (NTSR), are well documented, but their extent and importance are poorly understood among biotypes. This study examines the natural variation

Non-Target-Site Based Tolerance to Herbicides in Amaranthus palmeri [PDF]

open access: yes, 2018
Palmer amaranth, one of the most aggressive and damaging broadleaf weeds in the USA, has evolved resistance to multiple herbicide modes of action. The overall objective of this research was to elucidate the mechanisms by which Palmer amaranth adapt to ...

Different nontarget‐site mechanisms underlie resistance to dicamba and 2,4‐D in an Amaranthus tuberculatus population

open access: yesPest Management Science, Volume 81, Issue 7, Page 3464-3473, July 2025.
Weak phenotypic and genetic associations between resistance to dicamba and 2,4‐D suggest that different nontarget‐site mechanisms contribute to these traits in an Amaranthus tuberculatus population from Illinois. Abstract BACKGROUND Amaranthus tuberculatus (Moq.) Sauer (waterhemp) has emerged as one of several weed species that is resistant to ...

A point mutation in IAA34 confers resistance to the auxin herbicide 2,4‐D in Sisymbrium orientale

open access: yesPest Management Science, Volume 81, Issue 7, Page 3523-3531, July 2025.
A point mutation in domain IV of SoAux/IAA34‐R provides resistance to 2,4‐D. Abstract BACKGROUND Sisymbrium orientale has evolved resistance to 2,4‐D in Australia due to a 27 bp deletion in SoIAA2. However, one population of Sisymbrium orientale resistant to 2,4‐D (R1) did not contain the SoIAA2Δ27, suggesting another 2,4‐D resistance mechanism was ...

Population genomics of herbicide resistance in Alopecurus myosuroides [PDF]

open access: yes, 2022
Over the past 50 years, herbicides have often replaced mechanical and manual human weed control, thus representing a major factor in yield productivity in modern agriculture. Herbicide applications, however, exert strong selection pressures on weeds.

Multiple Origins or Widespread Gene Flow in Agricultural Fields? Regional Population Genomics of Herbicide Resistance in Bromus tectorum

open access: yesMolecular Ecology, Volume 34, Issue 11, June 2025.
ABSTRACT The repeated evolution of herbicide resistance in agriculture provides an unprecedented opportunity to understand how organisms rapidly respond to strong anthropogenic‐driven selection pressure. We recently identified agricultural populations of the grass species Bromus tectorum L. with resistance to multiple herbicides.

Biochemical and Molecular Knowledge about Developing Herbicide-Resistant Weeds [PDF]

open access: yes, 2017
Herbicide resistance is the genetic capacity of a weed population to survive an herbicide treatment that, under normal use conditions, would effectively control the resistant weed population.
