Climate change‐driven expansion of goosegrass highlights risks to global food production

Pest Management Science, EarlyView.
Climate change is expanding the climatic suitability of Eleusine indica into temperate agricultural regions, increasing its overlap with major soybean and maize production areas. These findings highlight a growing global threat to food security and the need for proactive weed management strategies.

Thirty years of glyphosate‐resistant crops and weeds: Current situation and future prospects

Pest Management Science, EarlyView.
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.

Generation of Maize 5-Enolpyruvylshikimate-3-Phosphate Synthase (EPSPS) Variants with Improved Glyphosate Tolerance

International Journal of Plant Biology
Glyphosate (N-phosphonomethylglycine) is a broad-spectrum, foliar-applied herbicide that inhibits 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) in plants.

A Modified phosphate-carrier protein theory is proposed as a non-target site mechanism For glyphosate resistance in weeds Teoria das proteínas carregadoras fosfato modificadas proposta como mecanismo de resistência ao herbicida glyphosate em plantas daninhas

Planta Daninha, 2010
Glyphosate is an herbicide that inhibits the enzyme 5-enolpyruvyl-shikimate-3-phosphate synthase (EPSPs) (EC 2.5.1.19). EPSPs is the sixth enzyme of the shikimate pathway, by which plants synthesize the aromatic amino acids phenylalanine, tyrosine, and ...

Deciphering the structure of Arabidopsis thaliana 5-enol-pyruvyl-shikimate-3-phosphate synthase: An essential step toward the discovery of novel inhibitors to supersede glyphosate

Computational and Structural Biotechnology Journal, 2022
Glyphosate interferes with plant aromatic metabolism through the inhibition of 5-enol-pyruvyl-shikimate-3-phosphate (EPSP) synthase [EPSPS, EC 2.5.1.19]. For this reason, EPSPS has been extensively studied in a vast array of organisms.

In rats, neurodevelopmental disorders induced by maternal hypoxia are associated with attenuated excitatory neurotransmission in the cingulate cortex

British Journal of Pharmacology, EarlyView.
Background and Purpose Maternal hypoxia is a recognised risk factor for neurodevelopmental disorders in offspring. Although rodent models of hypoxia have been reported, the detailed pathogenesis of maternal hypoxia‐induced neurodevelopmental disorders remains unclear.

Movement and Survival of Spodoptera litura (Lepidoptera: Noctuidae) Neonate Larvae on Cotton Expressing Bacillus thuringiensis Proteins

Entomologia Experimentalis et Applicata, EarlyView.
Spodoptera litura neonates showed increased movement on Bt‐expressing Bollgard 3 (BG) cotton leaf discs but did not initially avoid it. Survival was higher when larvae could move from BG3 to non‐Bt leaf discs. On whole plants, more larvae dispersed from hatching on BG3 cotton compared to non‐Bt cotton. These findings suggest the larval movement differs

EPSPS Gene Copy Number and Whole-Plant Glyphosate Resistance Level in Kochia scoparia.

PLoS ONE, 2016
Glyphosate-resistant (GR) Kochia scoparia has evolved in dryland chemical fallow systems throughout North America and the mechanism of resistance involves 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) gene duplication.

Shikimate pathway disruption in yeast induces metabolite self‐assembly into toxic aggregates

The FEBS Journal, EarlyView.
In Saccharomyces cerevisiae, shikimate pathway disruption induces toxic metabolite assemblies. Deleting ARO4 plus phenylalanine (Phe) feeding causes Phenylalanine accumulation, lowers ARO3 activity, and triggers amyloid‐like fibril formation. Deleting ARO3 plus tyrosine (Tyr) feeding leads to Tyrosine buildup and similar fibril assembly.

Growth and Reproduction of Glyphosate-Resistant and Susceptible Populations of Kochia scoparia.

PLoS ONE, 2015
Evolution of glyphosate-resistant kochia is a threat to no-till wheat-fallow and glyphosate-resistant (GR) cropping systems of the US Great Plains. The EPSPS (5-enol-pyruvylshikimate-3-phosphate synthase) gene amplification confers glyphosate resistance ...
