AHAS herbicide resistance endowing mutations: Effect on AHAS functionality and plant growth
(Oxford University Press, 2010-09)
Twenty-two amino acid substitutions at seven conserved amino acid residues in the acetohydroxyacid synthase (AHAS) gene have been identified to date that confer target-site resistance to AHAS-inhibiting herbicides in ...
AHAS Trp574Leu substitution in Raphanus sativus L.: screening, enzyme activity and fitness cost
(John Wiley & Sons Ltd, 2018-01-03)
Feral radish (Raphanus sativus L.) is a problematic weed that has become resistant to acetohydroxyacid synthase (AHAS) inhibitor herbicides due to the Trp574Leu mutation. An AHAS gene mutation that causes herbicide resistance ...
Ecological fitness cost associated with the AHAS Trp574Leu mutation in feral Raphanus sativus
(Wiley Blackwell Publishing, Inc, 2021-06)
Gene mutations endowing herbicide resistance may have negative pleiotropic effects on plant fitness. Quantifying these effects is critical for predicting the evolution of herbicide resistance and developing management ...
Differential expression of acetohydroxyacid synthase genes in sunflower plantlets and its response to imazapyr herbicide
(Elsevier Ireland, 2013-03)
Acetohydroxyacid synthase (AHAS) catalyzes the first reaction in branch chain amino acids biosynthesis. This enzyme is the target of several herbicides, including all members of the imidazolinone family. Little is known ...
Acetohydroxyacid synthase activity and transcripts profiling reveal tissue-specific regulation of ahas genes in sunflower
(Elsevier Ireland, 2014-04)
Acetohydroxyacid synthase (AHAS) is the target site of several herbicides and catalyses the first step in the biosynthesis of branched chain amino acid. Three genes coding for AHAS catalytic subunit (ahas1, ahas2 and ahas3) ...
AHAS Trp574Leu substitution in Raphanus sativus L.: screening, enzyme activity and fitness cost
(2018-07)
BACKGROUND: Feral radish (Raphanus sativus L.) is a problematic weed that has become resistant to acetohydroxyacid synthase (AHAS) inhibitor herbicides due to the Trp574Leu mutation. An AHAS gene mutation that causes ...
Characterization of sequence of Ahas and psbA genes related to herbicide resistance in Lupinus albus L.Caracterización de secuencias de los genes Ahas y psbA relacionados con resistencias a herbicidas en Lupinus albus L.
(Facultad de Ciencias Agrarias. Universidad Austral de Chile, 2015)
Broad resistance to acetohydroxyacid‐synthase‐inhibiting herbicides in feral radish (Raphanus sativus L.) populations from Argentina
(John Wiley & Sons Ltd, 2015-02-19)
BACKGROUND: Soon after the commercial release of sunflower cultivars resistant to imidazolinone herbicides, several uncontrolled feral radish (Raphanus sativus L.) populations were found in south-eastern Buenos Aires, ...
¿Cuánto le cuesta al nabón (Raphanus sativus L.) ser resistente a inhibidores de AHAS?: Implicancias para el manejo
(Asociación Argentina de Ciencia de las Malezas, 2021-06)
El nabón (Raphanus sativus L.) es una maleza problemática ampliamente difundida en las regiones templadas de América que ha desarrollado resistencia a los herbicidas inhibidores de la enzima acetohidroxiácido sintasa (AHAS) ...
Broad resistance to acetohydroxyacid-synthase-inhibiting herbicides in feral radish (Raphanus sativus L.) populations from Argentina
(2016-02)
BACKGROUND:
Soon after the commercial release of sunflower cultivars resistant to imidazolinone herbicides, several uncontrolled feral radish (Raphanus sativus L.) populations were found in south-eastern Buenos Aires, ...
