Non-target-site herbicide resistance: a family business.
We have witnessed a dramatic increase in the frequency and diversity of herbicide-resistant weed biotypes over the past two decades, which poses a threat to the sustainability of agriculture at both local and global levels. In addition, non-target-site mechanisms of herbicide resistance seem to be increasingly implicated. Non-target-site herbicide resistance normally involves the biochemical mo...
متن کاملMultiple-Herbicide Resistance Is Widespread in Roadside Palmer Amaranth Populations.
Herbicide-resistant Palmer amaranth is a widespread issue in row-crop production in the Midsouthern US. Palmer amaranth is commonly found on roadside habitats in this region, but little is known on the degree of herbicide resistance in these populations. Herbicide resistance in roadside Palmer amaranth populations can represent the spread of an adaptive trait across a selective landscape. A lar...
متن کاملImmunomodulation confers herbicide resistance in plants.
In order to create a novel mechanism for herbicide resistance in plants, we expressed a single-chain antibody fragment (scFv) in tobacco with specific affinity to the auxinic herbicide picloram. Transgenic tobacco plants and seedlings expressing this scFv against picloram were protected from its effect in a dose-dependent manner. This is the first successful use of an antibody to confer in vivo...
متن کاملMutation of a Locus of Arabidopsis thaliana Confers Resistance to the Herbicide Isoxaben.
Mutants resistant to the herbicide N-(3-[1-ethyl-1-methylpropyl]-5-isoxazolyl)-2,6,dimethoxybenzamide (isoxaben) were recovered from an M2 population of Arabidopsis thaliana. Two of these mutants, DH47 and DH48, had a high level of resistance in the homozygous state. Crosses of these mutants to marker strains, and to each other, showed that each contained a mutation at a single locus tightly li...
متن کاملA red and far-red light receptor mutation confers resistance to the herbicide glyphosate
Glyphosate is a widely applied broad-spectrum systemic herbicide that inhibits competitively the penultimate enzyme 5-enolpyruvylshikimate 3-phosphate synthase (EPSPS) from the shikimate pathway, thereby causing deleterious effects. A glyphosate-resistant Arabidopsis mutant (gre1) was isolated and genetic analyses indicated that a dysfunctional red (R) and far-red (FR) light receptor, phytochro...
