Abstract: Potato is a critical crop to European growers, both economically and agronomically as a break crop in the standard cereal rotation. As studies investigating the agronomic performance and environmental impact of disease resistant, GM potatoes come to an end across several sites in Europe, past discussions on achieving the effective coexistence of GM and …

Abstract: Field studies were conducted in 2008 in Ontario, OR and Paterson, WA to determine the effect of simulated glyphosate drift on ‘Ranger Russet’ potato, including visual injury, shikimic acid accumulation, and tuber yield. Glyphosate was applied at 8.5, 54, 107, 215, and 423 g ae ha−1; which corresponds to 0.01, 0.064, 0.126, 0.254, and …

Abstract: The analysis of the relevant part of the Institute of Nutrition Report showed that the studies were not carried out according to the accepted protocols for the biomedical assessment of GM food and feed (1). Many of the conclusions drawn by the authors do not correspond to the obtained data and therefore they are …

Abstract: Transgenic potato plants with the nptII gene coding for neomycin phosphotransferase (kanamycin resistance) as a selection marker were examined for the spread of recombinant DNA into the environment. We used the recombinant fusion of nptII with the tg4 terminator for a novel biomonitoring technique. This depended on natural transformation of Acinetobacter sp. strain BD413 …

Abstract: Larvicidal proteins encoded by cry genes from Bacillus thuringiensis were released in root exudates from transgenic B. thuringiensis corn, rice, and potato but not from B. thuringiensis canola, cotton, and tobacco. Nonsterile soil and sterile hydroponic solution in which B. thuringiensis corn, rice, or potato had been grown were immunologically positive for the presence …

Abstract: The article is devoted to the introduction of transgenic products into the consumer market. The impact of the genetically modified potatoes on the cytological and morphological parameters of mice was investigated. Transgenic potato plants were produced by agrobacterium-mediated transformation using genetic constructions 35S-proSmAMP with marker gene npt11 of the resistance to the kanamycin. An increase in hearts …

Abstract: The problems of the introduction of transgenic products into the consumer market were examined. The impact of the genetically modified potatoes on the cytological and morphological parameters in mice was investigated. An increase in body mass and in hearts mass and a decrease in spleens mass, degeneration of the ovaries and changing of the …

Abstract: Aim. To estimate the likelihood of transfer of kanamycin‐resistance gene (nptII) from commercially available genetically modified (GM) plants. Methods and Results. Acinetobacter sp. BD413 carrying a plasmid containing an inactivated nptII gene was treated with DNA derived from GM potato and GM papaya. Kanamycin‐resistant transformants were obtained at a frequency of 10–30 μg−1 DNA. Calculation …

Abstract: Substantial equivalence is widely accepted as assessment of feeds from genetically modified plants without changes in the composition. But this concept is not adequate for those with output traits, especially concerning their nutritive feeding value. The objective of this study is to evaluate rapeseed and potatoes belonging to the second generation of GM-plants… Although …

Abstract: A theoretical basis for resistance development to Bacillus thuringiensis by insect pests is presented with examples. The Colorado potato beetle, Leptinotarsa decemlineata (Say), is used as a model organism for discussing potential for resistance development, and operative factors that could influence resistance development are presented. The use of transgenic plants that produce high expression …

Abstract: Field experiments were conducted over a 4-yr period, 1989 to 1992, in southern Manitoba to investigate potato (5. tuberosum) response to simulated drift of the dimethylamine salt of dicamba, 2.8 to 22.2 g ai ha–1; alkanolamine salt of clopyralid, 4 to 32 g ai ha–1; and tribenuron, 0.15 to 1.2 g ai ha–1. Rate …

Abstract: Transgenic potatoes containing the marker genes NTP II and GUS were planted in the field and at varying distances (0–1, 1–2, 2–3, 10, 100 and 11000 m) from them were patches of untransformed potatoes of another variety. All seeds produced by the untransformed potatoes were collected after the flowering season and screened for the …

Abstract: In his clinical review on genetically modified foods Jones implies that Pusztai had tested only the effects of potato spiked with concanavalin A (a lectin) at the Rowett Institute. The initial dissemination of this incorrect information followed by the inappropriate suspension of Pusztai and the suspicion of fraud implied by instituting an audit according …

Abstract: Bt plants are plants that have been genetically modified to express the insecticidal proteins (e.g. Cry1Ab, Cry1Ac, Cry3A) from subspecies of the bacterium, Bacillus thuringiensis (Bt), to kill lepidopteran pests that feed on corn, rice, tobacco, canola, and cotton and coleopteran pests that feed on potato. The biomass of these transgenic Bt plants (Bt+) …

To the editor: Your May 29 editorial1 about the health risks of genetically modified (GM) food was apposite and addresses some of the important medical issues vigorously. It beggars belief that “badly designed, poorly carried out, inaccurately interpreted experiments” could have perpetuated such profound public debate for almost a year. Regrettably, among the correspondents who …

Abstract: Many researchers have hailed transgenic insecticidal crops—plants modified to produce insecticidal proteins derived from genes of the bacterium Bacillus thuringiensis (Bt)—as the most important technological advancement in insect pest management since the development of synthetic insecticides (Vaeck et al. 1987, Koziel et al. 1993, Perlak et al. 1990, 1993). At least 18 transgenic insecticidal …

Text: Biotechnology is big business.1 As such, the use of biotechnology to engineer plants, and the regulation of the resulting food crops, involves economic and trade issues, as well as science and health issues.2 Through modern biotechnology, selected individual genes are transferred from one organism into another, sometimes between nonrelated species, using recombinant DNA (rDNA) …

Text: Widespread distribution of genetically modified organisms (GMO) causes great biological risks for human and the Environment. Three kind of biological risks are described usually: ecological, nutrition and agrotechnical. The term genetically modified organisms (GMOs) refers to plants, microbes and animals with genes transferred from other species in order to produce certain novel characteristics (for …
