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 ... -
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 ... -
Enhancement of glyphosate efficacy on Amaranthus palmeri by exogenous quinate application
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 ... -
The pattern of shikimate pathway and phenylpropanoids after inhibition by glyphosate or quinate feeding in pea roots
The shikimate pathway is a metabolic route for the biosynthesis of aromatic amino acids (AAAs) (i.e. phenylalanine, tyrosine, and tryptophan). A key enzyme of shikimate pathway (5-enolpyruvylshikimate-3-phosphate synthase, ... -
Physiological action of herbicides inhibiting amino acid biosynthesis and their sustainable mixtures in Amaranthus palmeri sensitive and resistant to glyphosate
Durante el siglo pasado, la producción agrícola se ha ido incrementando en todo el mundo gracias a la mejora en sus técnicas de manejo. Una de las herramientas más poderosas para alcanzar ese incremento en la producción ... -
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 ...
