Alterations of oxidative status induced by amino acid synthesis-inhibiting herbicides in sensitive and target-site resistantpopulations of Amaranthus palmeri
(2023) Tesis doctoral / Doktoretza tesiaEntre los métodos de control de malas hierbas, los herbicidas aparecen como métodos rápidos y efectivos, y conforman el método más utilizado para el control de malas hierbas. Dos de los grupos de herbicidas más importantes ... -
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 ... -
Control de Ailanthus altissima en un ecosistema natural
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2017) Contribución a congreso / Biltzarrerako ekarpenaEl ailanto (Ailanthus altissima) es una especie considerada invasora en ecosistemas naturales. Se han realizado ensayos para su control, inyectando herbicida al tronco, con cuatro dosis de glifosato (36 %) mezclado con ... -
Cysteine proteases are activated in sensitive Amaranthus palmeri populations upon treatment with herbicides inhibiting amino acid biosynthesis
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 ... -
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, ... -
Fisiología de la resistencia múltiple a los herbicidas glifosato e inhibidores de acetolactato sintasa en amaranthus palmeri
Este trabajo se plantea en el marco de la necesidad de profundizar en el conocimiento de la fisiología de las plantas resistentes a herbicidas, lo que requiere, no solo identificar y dilucidar las bases moleculares de las ... -
Impairment of carbon metabolism induced by the herbicide glyphosate
The herbicide glyphosate reduces plant growth and causes plant death by inhibiting the biosynthesis of aromatic amino acids. The objective of this work was to determine whether glyphosate-treated plants show a carbon ... -
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 ... -
Inorganic–organic hybrids based on sepiolite as efficient adsorbents of caffeine and glyphosate pollutants
Sepiolite clay mineral was functionalized with (3-chloropropyl)triethoxysilane (ClPTES) or 3-[tri(ethoxy/methoxy)silyl] propylurea (TEMSPU) alkoxides and tested as adsorbent for herbicide glyphosate and also of caffeine, ... -
The moderate oxidative stress induced by glyphosate is not detected in Amaranthus palmeri plants overexpressing EPSPS
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 ... -
