Continued overexpression of EPSPS transgene enhances fitness in multigeneration crop–wild rice hybrids and its long-term environmental impact [PDF]

Frontiers in Plant Science
Transgene flow from genetically engineered (GE) crops to their wild relatives has aroused worldwide biosafety concerns. Environmental impact caused by transgene flow from GE glyphosate herbicide-tolerant rice overexpressing the endogenous EPSPS (5 ...

Identification of genetic elements associated with EPSPs gene amplification.

PLoS ONE, 2013
Weed populations can have high genetic plasticity and rapid responses to environmental selection pressures. For example, 100-fold amplification of the 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) gene evolved in the weed species Amaranthus palmeri

Dendritic coincidence detection of EPSPs and action potentials

Nature Neuroscience, 2001
We describe a mechanism for coincidence detection mediated by the interaction between backpropagating action potentials and EPSPs in neocortical pyramidal neurons. At distal dendritic locations, appropriately timed EPSPs or oscillations could increase the amplitude of backpropagating action potentials by three- to fourfold.

Effects of EPSPS Copy Number Variation (CNV) and Glyphosate Application on the Aromatic and Branched Chain Amino Acid Synthesis Pathways in Amaranthus palmeri

Frontiers in Plant Science, 2017
A key enzyme of the shikimate pathway, 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS; EC 2.5.1.19), is the known target of the widely used herbicide glyphosate.

Rethinking the Intrinsic Sensitivity of Fungi to Glyphosate

BioTech, 2022
The 5-enolpyruvylshikimate 3-phosphate synthase (EPSPS) is the central enzyme of the shikimate pathway to synthesize the three aromatic amino acids in fungi, plants, and prokaryotes. This enzyme is the target of the herbicide glyphosate.

Computational simulations and Ca2+ imaging reveal that slow synaptic depolarizations (slow EPSPs) inhibit fast EPSP evoked action potentials for most of their time course in enteric neurons.

PLoS Computational Biology, 2022
Transmission between neurons in the extensive enteric neural networks of the gut involves synaptic potentials with vastly different time courses and underlying conductances.

Simultaneous expression of 5-enol pyruvyl shikimate 3-phosphate synthase (epsps) and glyphosate oxidoreductase (gox) in transgenic canola plants towards enhancing resistance to glyphosate herbicide [PDF]

Zīst/shināsī-i Giyāhī-i Īrān, 2018
Canola (Brassica napus L.) is known as one of the most important oil-producing plants worldwide that has a high food value. Today, expansion of planting area of this plant has been highly considered.

Transcriptomic analysis reveals the transcription factors involved in regulating the expression of EPSPS gene, which confers glyphosate resistance of goosegrass (Eleusine indica)

Journal of Integrative Agriculture, 2021
Glyphosate inhibits the enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) and overexpression of the EPSPS gene is one of the molecular mechanisms conferring glyphosate resistance in weeds.

The First Case of Glyphosate Resistance in Johnsongrass (Sorghum halepense (L.) Pers.) in Europe

Plants, 2020
Six Johnsongrass populations suspected of being glyphosate resistant were collected from railways and freeways near Cordoba (SW Spain), where glyphosate is the main weed control tool.

EPSPs in rat neocortical neurons in vitro. I. Electrophysiological evidence for two distinct EPSPs [PDF]

Journal of Neurophysiology, 1989
1. To investigate excitatory postsynaptic potentials (EPSPs), intracellular recordings were performed in layer II/III neurons of the rat medial frontal cortex. The average resting membrane potential of the neurons was more than -75 mV and their average input resistance was greater than 20 M omega.
