GURTs: No Case for Field Trials

No peer-reviewed scientific data has been published on GURTs since 2000 that would alter the assessment and implications of CBD decision V/5-III, recommending that field trials not take place before ”appropriate scientific data can justify such testing”. In particular, there is an absence of:

  • Evidence that the components of GURTs (individually and in combination) perform with the degree of reliability and accuracy required for a stable and reliable GURT;
  • Evidence concerning impacts on the environment, biodiversity, and human health;
  • Evidence that v-GURTs applications to be used for bio-confinement will not allow gene flow to occur, via seed or pollen.

Unless reliable data from greenhouse trials, published in the peer-reviewed scientific literature, can show the existence of a complete GURT and its reliable and stable performance, and address outstanding issues, there is no reason for Parties to the CBD to consider field trials or case-by-case risk assessment.

V-GURTs (Terminator Technology)

This paper describes in brief the concepts and design behind Terminator technology or Genetic Use Restriction Technology (GURTs) in language accessible to non-scientists. It details the different elements that are theoretically required to assemble gene sequences designed to prevent the germination of seeds.

V-GURTs (Terminator)

Any biological containment system setting out to prevent gene flow of transgenes via pollen and seed must be 100% reliable and effective. At present there are a number of molecular containment strategies that aim to restrict gene flow either via pollen, seed or sprouting of vegetative organs (e.g. tubers). Such strategies include male sterility, maternal inheritance, seed sterility, prevention of sprouting, apomixis and temporal and tissue specific control.

Terminator Technology

Monsanto's latest flagship technology makes a nonsense of its claim that it seeks to feed the worlds hungry. On the contrary, it threatens to undermine the very basis of traditional agriculture - that of saving seeds from year to year. What's more, this “gene cocktail" will increase the risk that new toxins and allergens will make their way into the food chain.
