GM Sugarbeet Fructan Biosynthesis It has been previously demonstrated that traditional crops can be used to produce novel products. However, this approach has not been fully commercially exploited as some modified crops are not capable of producing sufficient amount of the compound of interest to offset the cost of processing. One of the reasons for this low output is that the precursors for the final product are present in low amounts in the plant. Because sugar beets are bred to produce high amounts of sucrose, this makes them a logical choice for fructan production.
The Dutch research institute, Plant Research International (http://www.plant.wageningen-ur.nl/), a part of Wageningen University and Research Centre, successfully modified sugar beets to produce fructan. The crop contains the 1-SST (1-sucrose:sucrose fructosyl transferase) from Jerusalem artichoke (Helianthus tuberosus). This enzyme mediates the first step for the conversion of sucrose into low molecular weight fructose polymers. |
