Mecanismos fisiológicos, bioquímicos y moleculares de tolerancia/resistencia a glifosato en especies de México
(Universidad de Córdoba, UCOPress, 2016)
La actividad agrícola es afectada por factores bióticos y abióticos. Las malas hierbas son uno de los factores bióticos más importantes que causan grandes pérdidas en el rendimiento de los cultivos (Oerke, 2006), y su ...
First Case of Multiple Resistance to EPSPS and PSI in Eleusine indica (L.) Gaertn. Collected in Rice and Herbicide-Resistant Crops in Colombia
(MDPI, 2021)
Eleusine indica is a highly competitive and difficult-to-control plant in annual and perennial crops. In Colombia, broad-spectrum herbicides, such as paraquat and glyphosate, have begun to present poor levels of control ...
Management of Glyphosate-Resistant Weeds in Mexican Citrus Groves: Chemical Alternatives and Economic Viability
(MDPI, 2019)
Glyphosate is a cheap herbicide that has been used to control a wide range of weeds (4–6 times/year) in citrus groves of the Gulf of Mexico; however, its excessive use has selected for glyphosate-resistant weeds. We evaluated ...
Fitness Cost of Imazamox Resistance in Wild Poinsettia (Euphorbia heterophylla L.)
(MDPI, 2020)
Wild poinsettia (Euphorbia heterophylla L.) is a difficult-to-control weed in soybean production in Brazil that has developed resistance to herbicides, including acetolactate synthase inhibitors. We investigated the potential ...
Ile-1781-Leu and Asp-2078-Gly Mutations in ACCase Gene, Endow Cross-resistance to APP, CHD, and PPZ in Phalaris minor from Mexico
(MDPI, 2015)
Herbicides that inhibit acetyl coenzyme A carboxylase (ACCase) are commonly
used in Mexico to control weedy grasses such as little seed canarygrass (Phalaris minor).
These herbicides are classified into three major ...
Clodinafop-Propargyl Resistance Genes in Lolium rigidum Guad. Populations Are Associated with Fitness Costs
(MDPI, 2018)
Amino acid substitutions that confer herbicide-resistance may cause fitness costs in mutant
plants at unfavorable levels in contrast to wild-species. The fitness costs in three Lolium rigidum
populations (AH3 (Ile-2041-Asn) ...
Point Mutations and Cytochrome P450 Can Contribute to Resistance to ACCase-Inhibiting Herbicides in Three Phalaris Species
(MDPI, 2021)
Species of Phalaris have historically been controlled by acetyl-coenzyme A carboxylase (ACCase)-inhibiting herbicides; however, overreliance on herbicides with this mechanism of action has resulted in the selection of ...
Non-Target Site Mechanisms Endow Resistance to Glyphosate in Saltmarsh Aster (Aster squamatus)
(MDPI, 2021)
Of the six-glyphosate resistant weed species reported in Mexico, five were found in citrus groves. Here, the glyphosate susceptibility level and resistance mechanisms were evaluated in saltmarsh aster (Aster squamatus), a ...
Physiological Fitness Associated to ACCase Target-Site Resistance Enhances Growth and Reproduction in Phalaris brachystachys
(MDPI, 2022)
Short-spike canarygrass (Phalaris brachystachys (Link.)) from Iranian wheat fields has developed resistance to acetyl-coenzyme A carboxylase (ACCase) inhibitors due to a target-site mutation (Ile-1781-Thr). Target-site ...
First Case of Conyza canadensis from Hungary with Multiple Resistance to Glyphosate and Flazasulfuron
(MDPI, 2018)
Conyza canadensis is a species invading large areas throughout the world, mainly due to its
ability to evolve herbicide resistance. In Hungary, extensive areas have been infested by this species
due to the difficulty in ...
