Interaction of glyphosate with amino acids of a genetically modified Roundup-resistant and not genetically modified soybean in aqueous solution in the conditions of in vitro
Abstract: In the first 2 cups placed 10 g of soybeans not GM and in one of them added 66 mg of Roundup (glyphosate) in dry powder form, and in the 3rd and 4th cups, similar to 10 g of GM Roundup-resistant soybean, and in one of them was added also 66 mg of Roundup …
Complex outcomes from insect and weed control with transgenic plants: Ecological surprises?
Abstract: Agriculture is fundamental for human survival through food production and is performed in ecosystems that, while simplified, still operate along ecological principles and retain complexity. Agricultural plants are thus part of ecological systems, and interact in complex ways with the surrounding terrestrial, soil, and aquatic habitats. We discuss three case studies that demonstrate how …
Glyphosate and Roundup® alter morphology and behavior in zebrafish
Abstract: Glyphosate has become the most widely used herbicide in the world, due to the wide scale adoption of transgenic glyphosate resistant crops after its introduction in 1996. Glyphosate may be used alone, but it is commonly applied as an active ingredient of the herbicide Roundup®. This pesticide contains several adjuvants, which may promote an unknown …
Environmental exposure to glyphosate and reproductive health impacts in agricultural population of Argentina
Abstract: Argentina annually utilizes 240,000 tones of glyphosate in industrial agriculture and a change in the profile of morbidity is perceived for physicians of agricultural areas; now reproductive disorders seem to prevail. The objective of this study is to determine concurrence of glyphosate exposure and reproductive disorders in a typical argentine agricultural town (Monte Maíz). An …
Glyphosate and AMPA concentrations in wind‐blown material under field conditions
Abstract: Agricultural intensification in fragile arid and semiarid environments has led to an increase in soil degradation, mainly through wind erosion. Argentina is an agricultural and cattle‐farming country, which has increased its productivity in the last few decades, widening the boundaries of farm land and the use of herbicides to control weeds. Glyphosate, which accounts for …
Virtual land and international trade
Suelo virtual y comercio internacional La agricultura es una actividad humana transformadora de su entorno y existen igualmente prácticas de producción y manejo que la acercan o alejan de modelos más o menos sostenibles; Mucho menos discutidos son los efectos que el comercio internacional y las demandas globales de productos primarios ejercen, como presiones exógenas, …
Field-based assessment of resistance to Bt corn by western corn rootworm (Coleoptera: Chrysomelidae)
Abstract: Western corn rootworm, Diabrotica virgifera virgifera LeConte, is a serious pest of corn and is managed with corn that produces insecticidal toxins derived from the bacterium Bacillus thuringiensis (Bt). Beginning in 2009, resistance to Cry3Bb1 corn, and severe injury to Cry3Bb1 corn in the field, was observed in Iowa. However, few data exist on …
Seed‐specific overexpression of phytoene synthase: Increase in carotenoids and other metabolic effects
Abstract: A bacterial phytoene synthase (crtB) gene was overexpressed in a seed‐specific manner and the protein product targeted to the plastid in Brassica napus (canola). The resultant embryos from these transgenic plants were visibly orange and the mature seed contained up to a 50‐fold increase in carotenoids. The predominant carotenoids accumulating in the seeds of the …
Distribution of glyphosate in chicken organs and its reduction by humic acid supplementation
Abstract: Glyphosate (N-(phosphonomethyl) glycine) is a most popular herbicide in agricultural practices throughout the world. It is possible that glyphosate spread in the ecosystems can reach plants, animals. The present work was directed to investigate the glyphosate residue in different organs of broiler chickens using ELISA and to study the possibility of its neutralisation using …
A plant 35S CaMV promoter induces long-term expression of luciferase in Atlantic salmon
Abstract: The long-term persistence and activity of a naked plasmid DNA (pGL3-35S) containing a luc gene (reporter gene) controlled by a plant 35S CaMV promoter was studied in Atlantic salmon (Salmo salar L.) after injection. Atlantic salmon (mean weight 70 grams) were injected intramuscularly with 100 μg of plasmid DNA. Blood, different tissues and organs …
Glyphosate influence on nitrogen, manganese, iron, copper and zinc nutritional efficiency in glyphosate resistant soybean
Abstract: After development of glyphosate-resistant (GR) soybean, there is a considerable raise in the use of this herbicide, with three to four applications during the culture cycle. Thus, these applications may be influencing the mineral nutrition of the crop. So, the aim of this research was evaluate the glyphosate influence on uptake, translocation and use efficiency …
