Background: In the last two decades, genetic engineering has led to the production of genetically modified or transgenic products in the world using the modern biotechnology. However, accepting such products by consumers is still in doubt with respect to their negative effects on the environment and human health. Thus, the present study aimed to evaluate the attitude of housewives in Yazd towar...
Due to population growth in the coming years, adequate food supply is the world's biggest problem, and it seems that one way to meet this need is to produce transgenic products. Transgenic products are created using modern technology to create or enhance a desirable property, such as increasing resistance to weeds or improving nutritional properties. The advantages of transgenic products includ...
World population growth and requirement to global food security, application of genetic engineering and utilization of transgenic organisms have made more important. Using this technology, without regarding to its risks, can cause loses to environment. To generate transgenic organisms, selection systems are applied that cause to selective growth of transformed cells. Antibiotic resistance genes...
due to ever-increasing global diffusion and related socio-economic implications, the detectionof genetically modified organisms (gmos) is very important. in this study, we design a plasmidcontaining two genes in mutated form as construct-specific (cp4 epsps) and event-specific(pd35s). it is applied for quantitative-competitor (qc) pcr as a simple and reliable method forthe detection of gm food....
Background and Objectives: Currently, increases in population of the world increase supply and food demands. Production of transgenic plants is one of the relative achievements. The aim of this study was to describe the consumer perceptions towards transgenic products. Materials & Methods: The study was carried out by sampling with the maximum diversity and participants enrolled until data sa...
Recent advances in gene technology have been applied to create fast-growing transgenic fish, which are of great commercial interest owing to their potential to shorten production cycles and increase food production. However, there is growing concern and speculation over the impact that escaped growth hormone (GH)-transgenic fish may have on the natural environment. To predict these risks it is ...
The comparative approach to food safety assessment is based on the idea that the safety of a new food can largely be determined by its comparison to the benchmark of commonly consumed foods already in the food supply (also called the 'conventional counterpart'). Any differences between the new food and its conventional counterpart are evaluated to determine their relevance to human health and s...
Environmental risk assessment of genetically modified organisms requires determination of their fitness and invasiveness relative to conspecifics and other ecosystem members. Cultured growth hormone transgenic coho salmon (Oncorhynchus kisutch) have enhanced feeding capacity and growth, which can result in large enhancements in body size (>7-fold) relative to nontransgenic salmon, but in nature...
Background: Rice seed proteins are lacking essential amino acids (EAAs). Genetic engineering off ers a fast and sustainable method to solve this problem as it allows the specifi c expression of heterologous EAA-rich proteins. The use of selectable marker gene is essential for generation of transgenic crops, but might also lead to potential environmental and food safety problems...
