Is Innate potato genetically modified?
The potatoes were modified to express the Galanthus nivalis agglutinin (GNA) gene from the Galanthus (snowdrop) plant, which caused them to produce GNA lectin protein that is toxic to some insects. This variety of potatoes is the one which was involved in the Pusztai affair.
In this study, CRISPR/Cas reagents expressing one of two single-guide RNA (sgRNA) targeting the potato ACETOLACTATE SYNTHASE1 (StALS1) gene were tested for inducing targeted mutations in callus and stable events of diploid and tetraploid potato using Agrobacterium-mediated transformation with either a conventional T-DNA or a modified geminivirus T-DNA.

Nov 27, 2018 · The Innate® potato has been modified using RNA interference (RNAi) technology to inhibit blackspot bruising and browning by reducing levels of asparagine and certain enzymes in the potato. In addition to white russet potatoes, ranger russet, russet Burbank and Atlantic potatoes have also been modified in this way.
Oct 17, 2018 · Given the nature of the potato industry, the most common potato varieties, such as Russet Burbank and Ranger Russet, will soon be contaminated with GMO stock. Other GMO Foods Have Hidden Concerns, Too. My book describes the many hidden issues of GMO potatoes, but GMO potatoes are not the exception. They are the rule.
Nov 08, 2018 · The “Innate” potato is a group of potato varieties that have had the same genetic alterations applied using a new form of genetic engineering known as RNA interference (RNAi). Five different potato varieties have been transformed, including the Ranger Russet, Russet Burbank, and Atlantic potatoes. Simplot also has two proprietary varieties. Simplot has designed the potato to reduce spotting, browning, and bruising by lowering certain enzymes and to reduce the amount of asparagine, a ...
Nov 19, 2015 · The use of Agrobacterium to introduce genes of interest is the most common method of stable transformation in potato, although other methods such as particle bombardment, protoplast transformation, and microinjection have been successful.
Aug 03, 2017 · Canadian officials say three types of potatoes genetically engineered by an Idaho company to resist the pathogen that caused the Irish potato famine are safe for the environment and safe to eat.
Genetically modified plants have been engineered for scientific research, to create new colours in plants, deliver vaccines, and to create enhanced crops. Plant genomes can be engineered by physical methods or by use of Agrobacterium for the delivery of sequences hosted in T-DNA binary vectors.
In the past decades, considerable progress has been made to establish the scientific foundation for the use of such modified cells. In particular, articular chondrocytes and, more recently, MSCs have been genetically modified using nonviral or viral methods.
