The Resistance Levels and Target-Site Based Resistance Mechanisms to Glyphosate in Eleusine indica from China

open access: yesAgronomy, 2022
The Dongting and Poyang Lakes are the important rice growing areas, and the Bohai Rim and Loess Plateau are the main producing areas of apples in China, where glyphosate has been used continuously to control weeds including Eleusine.

From knowledge to action: the importance of characterizing herbicide resistance mechanisms for implementing management strategies

open access: yesPest Management Science, EarlyView.
This review bridges the gap between understanding resistance mechanisms and applying them in weed management, highlighting how mechanistic insights reveal vulnerabilities that can guide more effective control strategies. Abstract Herbicide resistance remains one of the most intensively studied areas in weed science because of its direct consequences ...

EPSP depression following neocortical seizures in cat [PDF]

open access: yesEpilepsia, 2007
Summary To study the possible mechanism(s) underlying unresponsiveness following neocortical seizures, we recorded excitatory postsynaptic potentials (EPSPs) of cortical neurons evoked by ipsilateral cortical stimulation before and after spontaneous or elicited seizures. Regular‐spiking neurons (n = 32) were intracellularly recorded in association area

Effects of over-expressing a native gene encoding 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) on glyphosate resistance in Arabidopsis thaliana.

open access: yesPLoS ONE, 2017
Widespread overuse of the herbicide glyphosate, the active ingredient in RoundUp®, has led to the evolution of glyphosate-resistant weed biotypes, some of which persist by overproducing the herbicide's target enzyme, 5-enolpyruvylshikimate-3-phosphate ...

Increased Activity of 5-Enolpyruvylshikimate-3-phosphate Synthase (EPSPS) Enzyme Describe the Natural Tolerance of Vulpia myuros to Glyphosate in Comparison with Apera spica-venti

open access: yesAgriculture, 2021
Rattail fescue (Vulpia myuros (L.) C.C. Gmel.) is a self-pollinating winter annual grassy weed of winter annual crops. The problems with V. myuros are mostly associated with no-till cropping systems where glyphosate application before sowing or emergence

A Retinomorphic Graphene Transistor Implementing Direction‐ and Velocity‐Selective Computation for In‐Sensor Image Stabilization

open access: yesSmall, EarlyView.
A multi‐gated ion‐gel graphene transistor architecture emulates spatiotemporal dendritic filtering inspired by biological direction‐selective retinal circuits. Leveraging distributed resistance‐capacitive ionic relaxation delays under combined excitation‐inhibition pulse routines, the solid‐state device exhibits programmable direction‐selective index ...

Serotonin engages divergent 5‐HT receptor pathways for cell type‐resolved modulation of prefrontal layer 5 microcircuits

open access: yesBritish Journal of Pharmacology, EarlyView.
Serotonin differentially modulates layer 5 mPFC microcircuits through cell type‐specific pre‐ and postsynaptic receptor pathways. Presynaptic 5‐HT1BRs suppress glutamate and GABA release, whereas presynaptic and postsynaptic 5‐HT3ARs enhance fast‐spiking interneuron activity, whilst distinct pyramidal neuron subtypes exhibit divergent 5‐HT1AR‐ and 5 ...

Selective expression of the CP4 EPSPS in plants containing MON 87429. [PDF]

open access: yes, 2018
(A) Male tissue-specific cleavage of the CP4 EPSPS transcript. Full length CP4 EPSPS (approximately 2.1 kb) was detected in all tissues while cleaved products (B) Sequence-specific cleavage of the CP4 EPSPS.

Weak and straddling secondary nicotinic synapses can drive firing in rat sympathetic neurons and thereby contribute to ganglionic amplification

open access: yesFrontiers in Neurology, 2010
Interactions between nicotinic EPSPs critically determine whether paravertebral sympathetic ganglia behave as simple synaptic relays or as integrative centers that amplify preganglionic activity.
