Mechanism of resistance to glyphosate in Lolium perenne from Argentina
(Frontiers Media S. A, 2017-10)
n 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 ...
No fitness cost of glyphosate resistance endowed by massive EPSPS gene amplification in Amaranthus palmeri
(Springer, 2014-01)
Amplification of the EPSPS gene has been previously identified as the glyphosate resistance mechanism in many populations of Amaranthus palmeri, a major weed pest in U.S. agriculture. Here, we evaluate the effects of EPSPS ...
Constitutive overexpression of EPSPS by gene duplication is involved in glyphosate resistance in Salsola tragus
(Wiley, 2022-11)
Background: Glyphosate-resistant Salsola tragus accessions have been identified in the USA and Argentina; however, the mechanisms of glyphosate resistance have not been elucidated. The goal of this study was to determine ...
Do plants pay a fitness cost to be resistant to glyphosate?
(Wiley Blackwell Publishing, Inc, 2019-02-08)
We reviewed the literature to understand the effects of glyphosate resistance on plant fitness at the molecular, biochemical and physiological levels. A number of correlations between enzyme characteristics and glyphosate ...
Mechanism of Resistance to Glyphosate in Lolium perenne from Argentina
(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 ...
Protein identification before and after glyphosate exposure in Lolium multiflorum genotypes
(Wiley-Blackwell, 2018-05-01)
BACKGROUNDWeeds reduce crop yields, and among the methods used to control these plants, the use of chemicals is preferred. However, the repeated application of herbicides with the same mechanism of action selects for ...
P-Glycoprotein contributes to cell membrane depolarization of hippocampus and neocortex in a model of repetitive seizures induced by pentylenetetrazole in rats
(Bentham Science Publishers, 2013-03)
P-glycoprotein (P-gp) has been associated with pharmacoresistance and mechanisms regulating the membrane potential. However, at present it is unknown if P-gp overexpression in brain is associated with changes in membrane ...
One-step purification of 5-enolpyruvylshikimate-3-phosphate synthase enzyme from Mycobacterium tuberculosis
(2003-04-01)
Currently, there are 8 million new cases and 2 million deaths annually from tuberculosis, and it is expected that a total of 225 million new cases and 79 million deaths will occur between 1998 and 2030. The reemergence of ...
