Dynamics of glyphosate resistance in Lolium perenne: pollen-mediated gene flow under field conditions in Argentina
Yanniccari, Marcos Ezequiel; Istilart, Carolina Maria; Gimenez, Daniel Oscar; Castro, Ana Maria (MDPI, 2018-11)The genus Lolium has shown a high tendency to evolve resistance to herbicides. Considering the high level of allogamy of L. perenne and the importance of the wind as an agent for pollen dispersion, the aim of this work was ... -
Efecto del glifosato sobre el crecimiento y acumulación de azúcares libres en dos biotipos de lolium perenne de distinta sensibilidad al herbicida = Glyphosate effects on the growth and free sugar accumulation of two lolium perenn e biotypes with different herbicide sensitivity
Yanniccari, Marcos Ezequiel; Istilart, Carolina Maria; Gimenez, Daniel Oscar; Acciaresi, Horacio Abel; Castro, Ana Maria (Sociedade Brasileira da Ciência das Plantas Daninhas, 2012-03)El movimiento sistémico del glifosato está determinado por el transporte de fotoasimilados. A su vez, la capacidad de un destino de consumir los asimilados está condicionada por su actividad metabólica. Pese a su importancia, ... -
Effects of glyphosate on the movement of assimilates of two Lolium perenne L. populations with differential herbicide sensitivity
Yanniccari, Marcos Ezequiel; Istilart, Carolina Maria; Gimenez, Daniel Oscar; Castro, Ana Maria (2012-10)Glyphosate applications trigger the depletion of aromatic amino acid pools and the decrease of photosynthesis that results in changes in carbon metabolism. The aim of this work was to determine the effect of glyphosate on ... -
Glyphosate resistance in perennial ryegrass (Lolium perenne L.) from Argentina
Yanniccari, Marcos Ezequiel; Istilart, Carolina Maria; Gimenez, Daniel Oscar; Castro, Ana Maria (2012-02)In Argentina, glyphosate is the most widely used herbicide. A population of perennial ryegrass, subjected to two glyphosate applications per year during twelve years, was putatively identified as glyphosate-resistant based ... -
Inheritance of glyphosate resistance in Lolium perenne and hybrids with Lolium multiflorum
Yanniccari, Marcos Ezequiel; Istilart, Carolina Maria; Gimenez, Daniel Oscar; Castro, Ana Maria (2015-05)Glyphosate-resistant Lolium species have been selected in weed communities where glyphosate is the herbicide used almost exclusively for weed control. The rate of evolution of herbicide resistance is highly influenced by ... -
Mechanism of Resistance to Glyphosate in Lolium perenne from Argentina
Yanniccari, Marcos Ezequiel; Gómez Lobato, María Eugenia; Istilart, Carolina Maria; Natalucci, Claudia; Gimenez, Daniel Oscar; Castro, Ana Maria (2017-10)In Argentina, glyphosate resistance was reported in a Lolium perenne population after 12 years of successful herbicide use. The aim of the current paper was to put in evidence for the mechanism of glyphosate resistance of ...
