Resistance Mechanisms to Glyphosate in Lamarckia aurea (L.) Moench Found in Southern Spain

Agronomy
Glyphosate has been used for roadside weed control in southern Spain for over 40 years, and most populations of goldentop (Lamarckia aurea L.) Moench have putatively developed resistance to this active ingredient.

Transcriptome Profiling to Identify Genes Involved in Mesosulfuron-Methyl Resistance in Alopecurus aequalis

Frontiers in Plant Science, 2017
Non-target-site resistance (NTSR) to herbicides is a worldwide concern for weed control. However, as the dominant NTSR mechanism in weeds, metabolic resistance is not yet well-characterized at the genetic level.

Polymorphisms in Gag spacer peptide 1 confer varying levels of resistance to the HIV-1 maturation inhibitor bevirimat [PDF]

, 2010
Background: The maturation inhibitor bevirimat (BVM) potently inhibits human immunodeficiency virus type 1 (HIV-1) replication by blocking capsid-spacer peptide 1 (CA-SP1) cleavage. Recent clinical trials demonstrated that a significant proportion of HIV-

Fitness costs associated with evolved herbicide resistance alleles in plants [PDF]

, 2009
Predictions based on evolutionary theory suggest that the adaptive value of evolved herbicide resistance alleles may be compromised by the existence of fitness costs.

Altered Translocation Pattern as Potential Glyphosate Resistance Mechanism in Blackgrass (Alopecurus myosuroides) Populations from Lower Saxony

International Journal of Plant Biology
Glyphosate is a broad-spectrum herbicide widely used. After years of extensive usage, many weed species have developed resistance due to both target-site (TSR) and non-target-site resistance mechanisms (NTSRs).

Characterization of EiEPSPS Genes from Eleusine indica (L.) Gaertn. Ecotypes Differing in Glyphosate Resistance

Hayati Journal of Biosciences
Goosegrass (Eleusine indica (L.) Gaertn.) is among the most noxious weeds, particularly during the early growth stages of oil palm. Glyphosate is the most widely used herbicide globally for controlling E. indica by targeting the EPSPS enzyme. This study

Investigating the cost of adaptation in Amaranthus tuberculatus populations with evolved resistance to glyphosate [PDF]

Amaranthus tuberculatus (Common Waterhemp) is a prevalent, problematic weed in Midwestern USA, where genetically-modified crops are widely grown, resulting in multiple annual applications of glyphosate.

Target-Site Mutations Conferring Herbicide Resistance

, 2019
Mutations conferring evolved herbicide resistance in weeds are known in nine different herbicide sites of action. This review summarizes recently reported resistance-conferring mutations for each of these nine target sites.

Field-simulator studies of insecticide resistance to dimethylcarbamates and pyrethroids conferred by metabolic- and target site-based mechanisms in peach-potato aphids, Myzus persicae (Hemiptera: Aphididae)

, 2002
A range of insecticides was applied at recommended application rates against populations of Myzus persicae (Sulzer) carrying various combinations of three insecticide resistance mechanisms (carboxylesterase-based metabolic resistance and two target-site ...

Weed resistance diagnostic technologies to detect herbicide resistance in cerealgrowing areas. A review

Julius-Kühn-Archiv, 2012
Cereals are major crops used for food and feed. By 2050, the world population is expected to be close to 10 billion requiring a doubling of the food production from a fixed area of arable land.
