Glyphosate (N-phosphonomethyl-glycine) is a non-selective systemic herbicide widely used worldwide. The purpose of this study is to determine if glyphosate alone (GLPH) or in formulation with Roundup (G-RU) can affect granulosa cell proliferation and steroid production. Four experiments were conducted. In Exp. 1, 10 and 300 μg/mL of GLPH had no effect (P > 0.05) on cell numbers, estradiol or progesterone production, whereas 10 and 300 μg/mL of G-RU dramatically decreased (P < 0.05) cell numbers and estradiol and progesterone production...

Glyphosate is the most widely used herbicide worldwide and a critical tool for weed control in no-till cropping systems. However, there are concerns about non-target impacts of long-term glyphosate use on soil microbial communities. We investigated the impacts of repeated glyphosate treatments on bacterial communities in the soil and rhizosphere of wheat in soils with and without long-term history of glyphosate use. We cycled wheat in the greenhouse using soils from 4 paired fields under no-till (20+ years history of glyphosate) or no history of use...

The increase of agricultural areas with glyphosate-resistant (GR) crops, and use of this herbicide in Brazil, makes necessary to assess its impacts on non-target organisms. The objective was to evaluate the development, reproduction and life table parameters of Podisus nigrispinus (Heteroptera: Pentatomidae) reared on GR-soybean plants treated with glyphosate formulations (Zapp-Qi, Roundup-Transorb-R and Roundup-Original) at the recommended field dose (720g acid equivalent ha(-1)). Glyphosate formulations had no affect on nymph and adult weight of this predator...

A large share of genetically modified (GM) crops grown worldwide is processed into livestock feed. Feed safety of GM crops is primarily based on compositional equivalence with near-isogenic cultivars and experimental trials in rodents. However, feeding studies in target animals add to the evaluation of GM crops with respect to animal health. This review aimed to evaluate the possible health effects of feeding GM crops to livestock by reviewing scientific publications on experimental studies in ruminants, pigs, and poultry in which at least one of the following health parameters was investigated: body condition score, organ weight, haematology, serum biochemistry, histopathology, clinical examination, immune response, or gastrointestinal microbiota...

In Argentina, Chaetophractus villosus has a wide distribution that overlaps with agricultural areas where soybean is the predominant crop. In such areas the pesticide Roundup Full II® (RU) is widely applied. The genotoxic effect of its active ingredient glyphosate (RU is 66.2% glyphosate) on the peripheral blood lymphocytes of C. villosus was tested over a range of concentrations (280, 420, 560, 1120 μmol/L). Culture medium without glyphosate served as negative control, while medium containing mitomycin C served as positive control...

Mutations induced by pollutants may promote pathogen evolution for example by accelerating mutations conferring antibiotic resistance. Generally, evaluating the genome-wide mutagenic effects of long-term sublethal pollutant exposure at single-nucleotide resolution is extremely difficult. To overcome this technical barrier, we use the mutation accumulation/whole genome sequencing (MA/WGS) method as a mutagenicity test, to quantitatively evaluate genome-wide mutagenesis of Escherichia coli after long-term exposure to a wide gradient of the glyphosate-based herbicide (GBH) Roundup® Concentrate Plus...

Glyphosate-based herbicides (GBH) are the major pesticides used worldwide. Among them, the Roundup formulations are the most popular. Some aspects of GBH toxicity are well known, such as induction of oxidative stress. However, embryotoxicity is scarcely known. Therefore, the aim of the present study was to evaluate the effect of exposure to different Roundup Transorb R concentrations (0.36, 1.80, 3.62 and 5.43 mg glyphosate a.e./L) on Odontesthes humensis embryonic development. Embryos were sampled at three exposure times (48, 72 and 96 h)...

The aim of this study was to investigate the effects of Roundup Original(®), a glyphosate-based herbicide, against biochemical parameters including thiobarbituric acid-reactive substances (TBARS), protein carbonyl, enzymatic and nonenzymatic antioxidant responses and acetylcholinesterase (AChE) of jundiara fish (Leiarius marmoratus × Pseudoplatystoma reticulatum) at a sublethal concentration of 1.357 mg L(-1). Fish exposed to the herbicide for different periods (6-96 h) showed a significant increase of both hepatic and muscular TBARS and protein carbonyl...
