In crops targeted for the expression of a protein, the introduced DNA insert includes the protein-coding sequence (open reading frame) along with the regulatory sequences (promoter and terminator) required for its expression.Suppression of expression of specific viral and endogenous proteins has currently been achieved by inserting DNA that produces a complementary strand of RNA specific to viral RNA or endogenous RNA.
Improving wheat is a major challenge for agricultural scientists.
The world’s population continues to grow – and so does its appetite. Despite a “debate” stretching back to…If you believe this article from Collective Evolution, a site that claims to be “one of the worlds most popular alternative media company”, there is currently DNA from genetically modified plants floating…
Genetically engineered (GE) crops have been produced and marketed commercially for more than 20 years, and the foods obtained from them have been consumed by millions of people and billions of livestock animals (Van Eenennaam and Young, 2014).
The safety of GE crops introduced into the market has been assessed for potential to cause adverse effects to human and animal health or the environment in premarket approval processes.
The segments of interfering RNA can be single-stranded or double-stranded RNA (ds RNA) that activates natural suppression of the RNA by induction of specific ds RNAse or blocking RNA function.
The overall process is called RNA interference (RNAi) technology.This opinion is based on an extensive review of the published scientific literature in which the safety of foods from GE crops has been evaluated.This document does not address the environmental impact of GE organisms, such as potential gene transfer to nonengineered plants or general environmental impacts of agriculture which have previously been evaluated by economists and ecologists (eg, Brookes and Barfoot, 2013).Such genetic modifications are random, not targeted, and usually involve large-scale changes in the plant genome that have not been characterized.In contrast, genetic engineering involves precise and targeted introduction of a piece of DNA that has been thoroughly characterized and the resulting GE crops characterized using scientifically validated methods (Ladics , 2015).Furthermore, the genome-edited crops are not yet widely commercialized (Wolt , 2016), and extensive safety data for such crops are not yet available.Thus, this document focuses on the safety of foods obtained from or produced by the first and second generation GE food crops.Even though the safety of every new GE crop has been evaluated by various regulatory authorities throughout the world prior to its commercial release, the ongoing public debate about the safety of food and feed derived from GE plants has not abated.Such debates often overshadow an important fact that all crops used as human food or animal feed include varieties that have been developed through conventional breeding and selection over hundreds or thousands of years, or through intentional but random mutagenesis.This document reviews the safety data and information of GE crops and foods obtained from them.The purpose of this document is to present a current (2018) scientific opinion from the Society of Toxicology (SOT) regarding the safety of foods derived from GE crops.
