Cysteine proteases are activated in sensitive Amaranthus palmeri populations upon treatment with herbicides inhibiting amino acid biosynthesis
(Wiley, 2023)
Artículo / Artikulua,
The herbicides glyphosate and pyrithiobac inhibit the enzyme 5-enolpyruvylshikimate3-phosphate synthase (EPSPS) in the aromatic amino acid biosynthetic pathway and
acetolactate synthase (ALS) in the branched-chain amino ...
Unravelling the phytotoxic effects of glyphosate on sensitive and resistant Amaranthus Palmeri populations by GC-MS and LC-MS metabolic profiling
(MDPI, 2023)
Artículo / Artikulua,
Glyphosate, the most successful herbicide in history, specifically inhibits the activity of the enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS; EC 2.5.1.19), one of the key enzymes in the shikimate pathway. ...
Role of oxidative stress in the physiology of sensitive and resistant Amaranthus palmeri populations treated with herbicides inhibiting acetolactate synthase
(Frontiers Media, 2023)
Artículo / Artikulua,
The aim of the present study was to elucidate the role of oxidative stress in the
mode of action of acetolactate synthase (ALS) inhibiting herbicides. Two
populations of Amaranthus palmeri S. Watson from Spain (sensitive ...
The moderate oxidative stress induced by glyphosate is not detected in Amaranthus palmeri plants overexpressing EPSPS
(Elsevier, 2022)
Artículo / Artikulua,
The present study aimed to determine whether glyphosate-induced oxidative stress is directly related to the action mechanism of this herbicide (5-enolpyruvylshikimate-3-phosphate synthase or EPSPS inhibition) and analyse ...
Increased glyphosate-induced gene expression in the shikimate pathway is abolished in the presence of aromatic amino acids and mimicked by shikimate
(Frontiers Media, 2020)
info:eu-repo/semantics/article,
The herbicide glyphosate inhibits the plant enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) in the aromatic amino acid (AAA) biosynthetic pathway, also known as the shikimate pathway. Amaranthus palmeri is a ...
Enhancement of glyphosate efficacy on Amaranthus palmeri by exogenous quinate application
(Elsevier, 2019)
info:eu-repo/semantics/article,
Glyphosate is a widely used herbicide targeting the enzyme 5-enolpyruvylshikimate 3-phosphate synthase (EPSPS) in the aromatic amino acid biosynthesis pathway (shikimate pathway) and provoking
accumulation of quinate, a ...
ERF-VII transcription factors induce ethanol fermentation in response to amino acid biosynthesis-inhibiting herbicides
(Oxford University Press, 2019)
info:eu-repo/semantics/article,
Herbicides inhibiting either aromatic or branched-chain amino acid biosynthesis trigger similar physiological responses in plants, despite their different mechanism of action. Both types of herbicides are known to activate ...
Physiological performance of glyphosate and imazamox mixtures on Amaranthus palmeri sensitive and resistant to glyphosate
(Nature Research, 2019)
info:eu-repo/semantics/article,
The herbicides glyphosate and imazamox inhibit the biosynthetic pathway of aromatic amino acids (AAA) and branched-chain amino acids (BCAA), respectively. Both herbicides share several physiological effects in the processes ...
Primary metabolism in an Amaranthus palmeri population with multiple resistance to glyphosate and pyrithiobac herbicides
(Elsevier, 2022)
info:eu-repo/semantics/article,
The objective of this work was to characterize the resistance mechanisms and the primary metabolism of a multiple resistant (MR) population of Amaranthus palmeri to glyphosate and to the acetolactate synthase (ALS) inhibitor ...
Hypoxic treatment decreases the physiological action of the herbicide imazamox on pisum sativum roots
(MDPI, 2020)
info:eu-repo/semantics/article,
The inhibition of acetolactate synthase (ALS; EC 2.2.1.6), an enzyme located in the biosynthetic pathway of branched-chain amino acids, is the target site of the herbicide imazamox. One of the physiological effects triggered ...
