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 ... -
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 ... -
Introgression from local cultivars is a driver of agricultural adaptation in Argentinian weedy rice
Presotto, Alejandro Daniel; Hernández, Fernando; Vercellino, Roman Boris; Kruger, Raúl; Fontana, Maria Laura; Ureta, Maria Soledad; Crepy, Maria Andrea; Auge, Gabriela; Caicedo, Ana (Wiley, 2024-04-27)Weedy rice, a pervasive and troublesome weed found across the globe, has often evolved through fertilization of rice cultivars with little importance of crop-weed gene flow. In Argentina, weedy rice has been reported as ... -
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 ...
