AHAS Trp574Leu substitution in Raphanus sativus L.: screening, enzyme activity and fitness cost
Vercellino, Roman Boris; Pandolfo, Claudio Ezequiel; Breccia, Gabriela; Cantamutto, Miguel Angel; Presotto, Alejandro Daniel (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 ... -
Broad resistance to acetohydroxyacid-synthase-inhibiting herbicides in feral radish (Raphanus sativus L.) populations from Argentina
Pandolfo, Claudio Ezequiel; Presotto, Alejandro Daniel; Moreno, Florencia; Dossou, Ida; Migasso, Juan P.; Sakima, Ernesto; Cantamutto, Miguel Angel (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, ... -
Can achene selection in sunflower crop–wild hybrids by pre-dispersal seed predators hasten the return to phenotypically wild sunflowers
Presotto, Alejandro Daniel; Pandolfo, Claudio Ezequiel; Poverene, Maria Monica; Cantamutto, Miguel Angel (2016-04)Bird attack is a serious limitation to sunflower yield in several regions of the world, but it could also cause selection. The wild Helianthus annuus, naturalized in several regions of the world, hybridizes with the crop ... -
Crop-wild sunflower hybridization can mediate weediness throughout growth-stress tolerance trade-offs
Presotto, Alejandro Daniel; Hernández, Fernando; Díaz, Marina; Fernández Moroni, Ivana; Pandolfo, Claudio Ezequiel; Basualdo, Jessica; Cuppari, Selva Yanet; Cantamutto, Miguel Angel; Poverene, María Mónica (2017-11)Agricultural weeds are plants well-adapted to agricultural environments interfering directly and indirectly with crop production and causing important economic losses worldwide. Crop-wild hybridization is one of the main ... -
Herbicide-resistant weeds from dryland agriculture in Argentina
Oreja, Fernando H.; Moreno, Natalia; Gundel, Pedro Emilio; Vercellino, Roman Boris; Pandolfo, Claudio Ezequiel; Presotto, Alejandro Daniel; Perotti, Valeria Elisa; Permingeat, Hugo; Tuesca, Daniel Horacio; Scursoni, Julio Alejandro; Dellaferrera, Ignacio Miguel; Cortes, Eduardo; Yanniccari, Marcos; Vila-Aiub, Martín Miguel (Wiley, 2024-01)We reviewed and performed a quantitative synthesis on herbicide-resistant weeds from rain-fed crops in Argentina. Twenty-four weed species distributed in the main extensive crops (soybean, maize, wheat, barley, oilseed ... -
IMI resistance associated to crop-weed hybridization in a natural Brassica rapa population: characterization and fate
Ureta, Maria Soledad; Torres Carbonell, Francisco Javier; Pandolfo, Claudio Ezequiel; Presotto, Alejandro Daniel; Cantamutto, Miguel Angel; Poverene, María Mónica (2017-03)Wild turnip (Brassica rapa) is a common weed and a close relative to oilseed rape (Brassica napus). The Clearfield® production system is a highly adopted tool which provides an alternative solution for weed management, but ... -
The roles of light and pericarp on seed dormancy and germination in feral Raphanus sativus (Brassicaceae)
Vercellino, Roman Boris; Pandolfo, Claudio Ezequiel; Cerrotta, Alfonso; Cantamutto, Miguel Angel; Presotto, Alejandro Daniel (Wiley, 2019-08-19)The timing of seed germination may determine the success of a weed species in an agroecosystem, and its expression is modulated by environmental conditions, but also by seed physiology and anatomy. The aims of this study ... -
Transgene escape and persistence in an agroecosystem: the case of glyphosate-resistant Brassica rapa L. in central Argentina
Pandolfo, Claudio Ezequiel; Presotto, Alejandro Daniel; Torres Carbonell, Francisco Javier; Ureta, Maria Soledad; Poverene, María Mónica; Cantamutto, Miguel Angel (2018-03)Brassica rapa L. is an annual Brassicaceae species cultivated for oil and food production, whose wild form is a weed of crops worldwide. In temperate regions of South America and especially in the Argentine Pampas region, ... -
Transgenic glyphosate-resistant oilseed rape (Brassica napus) as an invasive weed in Argentina: detection, characterization, and control alternatives
Pandolfo, Claudio Ezequiel; Presotto, Alejandro Daniel; Torres Carbonell, Francisco Javier; Ureta, Maria Soledad; Poverene, María Mónica; Cantamutto, Miguel Angel (2016-12)The presence of glyphosate-resistant oilseed rape populations in Argentina was detected and characterized. The resistant plants were found as weeds in RR soybeans and other fields. The immunological and molecular analysis ...
