Phenomena responsible for disturbances
Gene silencing - where transgenes "can be unstable and become silenced" [ie switched off] Explanation: There are strong protection mechanisms against the uptake of foreign genes. These may silence the inserted gene ...

GeneWatch UK - Techniques for Genetically Modifying Plants - A basic guide on how plants are genetically modified.
GM techniques are not sufficiently accurate or precise enough to allow the introduction of a gene or gene(s) at one particular site in the genome. Rather, there may be multiple copies ... levels of naturally occurring toxins or allergenic proteins; silencing of genes in subsequent generations if multiple copies exist as a result of transgene silencing. ↑ Top Please note that GeneWatch UK should ...

Say No To GMOs! - November 2007
Researchers have created plants that kill insects by disrupting their gene expression. The crops, which initiate a gene-silencing response called RNA interference, are a step beyond existing genetically ... , eating double-stranded RNA is enough to cause gene silencing. This is surprising: in previous research, RNA interfered with organisms' gene expression only when it was injected. "People have ...

Genetically Modified Foods: Harmful or Helpful?
For example, plant geneticists can isolate a gene responsible for drought tolerance and insert that gene into a different plant. The new genetically-modified plant will gain ... 3, pp 628-627, Jun 2001) Post-transcriptional gene silencing in plum pox virus resistant transgenic European plum containing the plum pox potyvirus coat protein gene (Transgenic Research, Vol 10, No 3, ...

Benjamin Franklin Medal in Life Science - The Franklin Institute Awards
By 1999, however, David Baulcombe's work spotting small (or micro-) RNAs associated with gene silencing in plants helped catapult the work to the forefront. This was also fueled by ... several examples of gene silencing, including one related to viral defense. They deduced that the newly discovered small RNAs, now known as small interfering RNAs or siRNAs, guided the silencing to the ...
