Diversity and Spread of Acetolactate Synthase Allelic Variants at Position 574 Endowing Resistance in Amaranthus hybridus in Italy

open access: yesPlants, 2023
Poor control of Amaranthus spp. with herbicides inhibiting acetolactate synthase (ALS) has been observed for several years in soybean fields in north-eastern Italy, but to date only a few ALS-resistant populations have been confirmed.

HIV therapy: Managing resistance [PDF]

open access: yesProceedings of the National Academy of Sciences, 2000
Over the last years, a number of potent drugs have been developed that inhibit HIV-1 replication in vivo . Treatment regimes involving a combination of three or more different drugs can induce a decline in virus load by several orders of magnitude, as well as a significant rise in the CD4 cell count.

Framework for an expert evaluation for the evolution of weed resistance

open access: yesJulius-Kühn-Archiv, 2014
The apparent rate of evolution of resistance of weeds to herbicides has increased substantially over the past decade. Data suggests phenotypic expression is affected by the mechanism of action of the herbicide, the taxonomy of the weed, the extent and ...

Characterization of Asian Corn Borer Resistance to Bt Toxin Cry1Ie

open access: yesToxins, 2017
A strain of the Asian corn borer (ACB), Ostrinia furnacalis (Guenée), has evolved >800-fold resistance to Cry1Ie (ACB-IeR) after 49 generations of selection. The inheritance pattern of resistance to Cry1Ie in ACB-IeR strain and its cross-resistance to

Management of resistant hypertension [PDF]

open access: yesCanadian Medical Association Journal, 2015
In their review, Padwal and colleagues[1][1] made an interesting and important omission. Variants of Liddle syndrome (genetic mutations affecting the renal tubular epithelial sodium channel, ENac, causing salt and water retention and loss of potassium), are far commoner than most physicians ...

Overlapping Residual Herbicides for Control of Photosystem (PS) II- and 4-Hydroxyphenylpyruvate Dioxygenase (HPPD)-Inhibitor-Resistant Palmer amaranth (Amaranthus palmeri S. Watson) in Glyphosate-Resistant Maize

open access: yesFrontiers in Plant Science, 2018
A Palmer amaranth (Amaranthus palmeri S. Watson) biotype has evolved resistance to photosystem (PS) II- (atrazine) and 4-hydroxyphenylpyruvate dioxygenase (HPPD)-inhibiting herbicides (mesotrione, tembotrione, and topramezone) in maize seed production ...

Complex Interactions between Fungal Avirulence Genes and Their Corresponding Plant Resistance Genes and Consequences for Disease Resistance Management

open access: yesFrontiers in Plant Science, 2017
During infection, pathogens secrete an arsenal of molecules, collectively called effectors, key elements of pathogenesis which modulate innate immunity of the plant and facilitate infection.

Evaluating Cross-Resistance to Cry and Vip Toxins in Four Strains of Helicoverpa armigera With Different Genetic Mechanisms of Resistance to Bt Toxin Cry1Ac

open access: yesFrontiers in Microbiology, 2021
Evolution of resistance by pests has diminished the efficacy of transgenic crops producing insecticidal proteins from Bacillus thuringiensis (Bt). In China, where transgenic cotton producing Bt toxin Cry1Ac has been planted since 1997, field control ...
