The Dominance of the Herbicide Resistance Cost in Several Arabidopsis thaliana Mutant Lines
Resistance evolution depends upon the balance between advantage and disadvantage (cost) conferred in treated and untreated areas. By analyzing morphological characters and simple fitness components,… Expand
PCR-based detection of resistance to acetyl-CoA carboxylase-inhibiting herbicides in black-grass (Alopecurus myosuroides Huds) and ryegrass (Lolium rigidum gaud).
A simple method based upon allele-specific PCR was developed to detect an isoleucine-leucine substitution in the gene encoding chloroplastic acetyl-coenzyme A carboxylase (ACCase) in two gramineous… Expand
Inheritance of fenoxaprop-P-ethyl resistance in a blackgrass (Alopecurus myosuroides Huds.) population
Abstract A blackgrass population has developed resistance to fenoxaprop-P-ethyl following field selection with the herbicide for 6 consecutive years. Within this population, 95% of the individuals… Expand
Occurrence of genetically modified oilseed rape seeds in the harvest of subsequent conventional oilseed rape over time
Is returning to a conventional crop possible after growing a genetically modified (GM) variety? Oilseed rape volunteers in oilseed rape crops can cause seed admixture in the harvest. Farmers who… Expand

In Chenopodium album two different levels of atrazine resistance have been found according to following criteria: lethal dose and leaf fluorescence curve. The intermediate (I) phenotype is… Expand
Enhanced activity of several herbicide-degrading enzymes: a suggested mechanism responsible for multiple resistance in blackgrass (Alopecurus myosuroides Huds.)
Cette experimentation a pour but d'analyser l'eventuelle implication de monooxygenases a cytochrome P450 (P450(s)) et de glutathione S-transferases (GST(s)) dans les resistances multiples observees… Expand
Isoenzymatic variations in populations of Chenopodium album L. resistant and susceptible to triazines
Abstract As part of a study of triazine resistance in weed species, the authors have collected several resistant populations of Chenopodium album in different areas in France. A study of intra- and… Expand
Resistance to acetyl CoA carboxylase-inhibiting herbicides in Lolium multiflorum

Abstract A Lolium multiflorum Lam. biotype resistant to diclofop-methyl was found in a Triticum aestivum field in France (Normandy) that had been treated for several years with diclofop-methyl. Based… Expand
Chlamydomonas reinhardtii as a model system for pro‐active herbicide resistance evolution research
Modern herbicides greatly contribute to world agricultural production but their sustainability is threatened by the widespread evolution of herbicide resistant weedy plant populations. Despite the… Expand
Evaluation of cropping systems for management of herbicide-resistant populations of blackgrass (Alopecurus myosuroides Huds.).
Abstract Simplification of cropping systems often leads to an increase in weed populations which require an intensive use of herbicides to maintain populations at an acceptable level. Due to a heavy… Expand
