Glyphosate resistance in perennial ryegrass (Lolium perenne L.) is associated with a fitness penalty
(2016)
The net selection effect of herbicides on herbicide-resistance traits in weeds is conditioned by the fitness benefits and costs associated with resistance alleles. Fitness costs play an important evolutionary role preventing ...
Glyphosate resistance in perennial ryegrass (Lolium perenne L.) from Argentina
(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 ...
CONTROL OF Conyza bonariensis WITH GLYPHOSATE ASSOCIATED TO ADJUVANTS APPLIED WITH DIFFERENT SPRAY NOZZLES
(Univ Federal Uberlandia, 2017-03-01)
The study aimed to evaluate the control of Conyza bonariensis in delayed post-emergence stage using different spray nozzles and solutions with and without adjuvants; and to verify the occurrence of resistance to glyphosate, ...
Controle de conyza Bonariensis com glyphosate associado a adjuvantes aplicados com diferentes pontas de Pulverização
(2017-03-01)
The study aimed to evaluate the control of Conyza bonariensis in delayed post-emergence stage using different spray nozzles and solutions with and without adjuvants; and to verify the occurrence of resistance to glyphosate, ...
Glyphosate applied at low doses can stimulate plant growth
(John Wiley & Sons Ltd, 2008-04-01)
BACKGROUND: Glyphosate blocks the shikimic acid pathway, inhibiting the production of aromatic amino acids and several secondary compounds derived from these amino acids. Non-target plants can be exposed to low doses of ...

Metabolic profiling of glyphosate-resistant sourgrass (Digitaria insularis)
(Cambridge Univ Press, 2020-10-01)
Putative glyphosate-resistant sourgrass was collected to determine its resistance level and to evaluate its metabolic profile after resistance. Although accumulation of shikimic acid is known to occur in glyphosate-susceptible ...
Differential resistance mechanisms to Glyphosate result in fitness cost for Lolium perenne and L. multiflorum
(Frontiers in Plant Science, 2018)
Non-target-site glyphosate resistance in Echinochloa colona from Western Australia
(Elsevier, 2018-10)
An Echinochloa colona population from Western Australia has evolved resistance to glyphosate. This current study investigates the physiological, molecular and biochemical basis of glyphosate resistance in this population. ...
Contrasting plant ecological benefits endowed by naturally occurring EPSPS resistance mutations under glyphosate selection
(Wiley Blackwell Publishing, Inc, 2021-03)
Concurrent natural evolution of glyphosate resistance single- and double-point EPSPS mutations in weed species provides an opportunity for the estimation of resistance fitness benefits and prediction of equilibrium resistance ...
