Genetic Use Restriction Technologies (GURTS)

is the “official” name for Terminator technology that is used at the United Nations and by scientists. It refers to a general category of technologies that, in their design, provide a mechanism to switch previously introduced genes on or off, using external inducers like chemicals or physical stimuli (e.g. heat shock). This mechanism allows for restricted use or performance of transgenes. There are two main categories of GURTs, namely trait-related or T-GURTs and variety-related or V-GURTs. Whilst T-GURTs aims to control the use of traits such as insect resistance, stress tolerance or production of nutrients, V-GURTs aims to control reproductive processes that will result in seed sterility, thus affecting the viability of the whole variety. (V-GURTs is a concept, with many different potential designs.) The ability to switch the GURTs mechanism on or off externally enables the producer to exercise control either over traits or the viability of seeds (Source: EcoNexus See www.econexus.info)
