An aerated axenic hydroponic system for the application of root treatments: exogenous pyruvate as a practical case
Background: Hydroponic systems are a convenient platform for plant cultivation when treatments are applied to the roots because they provide precise control of the composition of the growth medium, ensuring the availability ... -
Both foliar and residual applications of herbicides that inhibit amino acid biosynthesis induce alternative respiration and aerobic fermentation in pea roots
The objective of this work was to ascertain whether there is a general pattern of carbon allocation and utilisation in plants following herbicide supply, independent of the site of application: sprayed on leaves or supplied ... -
Branched-chain amino acid biosynthesis inhibitors: herbicide efficacy is associated with an induced carbon–nitrogen imbalance
Acetolactate synthase (ALS; EC 4.1.3.18) and ketol-acid reductoisomerase (KARI; EC 1.1.1.86) are two consecutive enzymes in the biosynthesis of branched-chain amino acids. Several commercial herbicides inhibit ALS as their ... -
Characterization of the Amaranthus palmeri physiological response to glyphosate in susceptible and resistant populations
The herbicide glyphosate inhibits the plant enzyme 5-enolpyruvylshikimate3-phosphate synthase (EPSPS) in the aromatic amino acid (AAA) biosynthetic pathway. The physiologies of an Amaranthus palmeri population exhibiting ... -
Efecto del glifosato en la expresión génica de la ruta del siquimato en Amaranthus palmeri
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2017) Contribución a congreso / Biltzarrerako ekarpenaEste estudio ha abordado el efecto del herbicida glifosato en la regulación de la ruta del siquimato en la especie Amaranthus palmeri, comparando una población sensible a glifosato con una población resistente. Se han ... -
Efecto del glifosato y de diferentes intermediarios metabólicos en la regulación de la ruta del siquimato
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2017) Contribución a congreso / Biltzarrerako ekarpenaEn este estudio se han abordado los mecanismos de regulación de la ruta del siquimato en la biosíntesis de los aminoácidos aromáticos. Para ello se han comparado el contenido de siquimato y de los enzimas EPSPS ... -
Effects of EPSPS Copy Number Variation (CNV) and glyphosate application on the aromatic and branched chain amino acid synthesis pathways in Amaranthus palmeri
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. Glyphosate resistance in Amaranthus palmeri, one of ... -
ERF-VII transcription factors induce ethanol fermentation in response to amino acid biosynthesis-inhibiting herbicides
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 ... -
Fermentation and alternative oxidase contribute to the action of amino acid biosynthesis-inhibiting herbicides
Acetolactate synthase inhibitors (ALS-inhibitors) and glyphosate (GLP) are two classes of herbicide that act by the specific inhibition of an enzyme in the biosynthetic pathway of branched-chain or aromatic amino acids, ... -
Hypoxic treatment decreases the physiological action of the herbicide imazamox on pisum sativum roots
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 ... -
Increased glyphosate-induced gene expression in the shikimate pathway is abolished in the presence of aromatic amino acids and mimicked by shikimate
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 ... -
Induction of the PDH bypass and upregulation of the ALDH7B4 in plants treated with herbicides inhibiting amino acid biosynthesis
Imazamox and glyphosate represent two classes of herbicides that inhibit the activity of acetohydroxyacid synthase in the branched-chain amino acid biosynthesis pathway and the activity of 5-enolpyruvylshikimate-3-phosphate ... -

Physiological approach to the use of the natural compound quinate in the control of sensitive and resistant Papaver rhoeas
Quinate (1,3,4,5-tetrahydroxycyclohexanecarboxylate) is a compound synthesized in plants through a side-branch of the shikimate biosynthesis pathway, which is accumulated after glyphosate and acetolactate synthase inhibiting ... -
Physiological performance of glyphosate and imazamox mixtures on Amaranthus palmeri sensitive and resistant to glyphosate
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 ... -
Proteolytic pathways induced by herbicides that inhibit amino acid biosynthesis
Background: The herbicides glyphosate (Gly) and imazamox (Imx) inhibit the biosynthesis of aromatic and branched-chain amino acids, respectively. Although these herbicides inhibit different pathways, they have been reported ... -
