Ecological Risks and Benefits of Transgenic Plants
The spread of commercial growing of transgenic crops has been very rapid, with such crops being grown on 44.2 million ha in 13 countries in 2000. Most currently grown transgenic plants are either herbicide or insect resistant, but research into other possibilities is intense. There are potentially significant environmental effects of this technology, as well as sharply conflicting claims about ...
متن کاملEvaluation of potential risks associated with recombination in transgenic plants expressing viral sequences.
Virus-resistant transgenic plants have been created primarily through the expression of viral sequences. It has been hypothesized that recombination between the viral transgene mRNA and the RNA of an infecting virus could generate novel viruses. As mRNA/viral RNA recombination can occur in virus-resistant transgenic plants, the key to testing this risk hypothesis is to compare the populations o...
متن کاملThe ecological risks and benefits of genetically engineered plants.
Discussions of the environmental risks and benefits of adopting genetically engineered organisms are highly polarized between pro- and anti-biotechnology groups, but the current state of our knowledge is frequently overlooked in this debate. A review of existing scientific literature reveals that key experiments on both the environmental risks and benefits are lacking. The complexity of ecologi...
متن کاملPollution potential and ecological risk of heavy metals in municipal wastewater treatment plants sludge
Background and Objective: Application of sewage sludge contaminated with heavy metals may cause health and ecological concern. Ecological risk and heavy metals content of sewage sludge from wastewater treatment plants of East Azerbaijan province were evaluated in the present study. Materials and Methods: Nine composite samples were taken and analyzed for heavy metals. The geo-accumulation inde...
متن کاملResponse to Some Biosafety Concerns of Transgenic Plants
Plant genetic engineering has been the fastest technology adopted in human history to achieve quantitative and qualitative superiority by farmers. This technology has real benefits to the environment and the livelihood of farmers. Unfortunately, despite numerous credible scientific studies on the safety of GM products for the consumer and the environment, this technology still faces misleading ...
