General Information
Field trial with chicory plants expressing additional fructosyltransferases
EN
17 Feb 2004
Risk assessment details
  • Chicory modified for increased inulin expression
    | Plant Research International | Increased inulin, Resistance to antibiotics (Kanamycin)
Methodology and points to consider
EN
Outcrossing to wild chicory is possible. The trial will be confined to the experimental plot. If any effect should occur, it will be confined to this plot area.
EN
EN
The risk of any adverse effect is considered to be neglilible.

At this moment there is uncertainty concerning the extent the alteration of the soluble carbohydrate content of the chicory root could have an effect on different aspects of the life of the plants. The most relevant aspects of concern is an increased frost tolerance affect and an altered ability to flower and to set seeds. For this reason the GM chicory will be grown only during the vegetative part of their reproductive cycle and will not be allowed to flower.
EN
The field trials will be conducted in the Central Netherlands. In this same region commercial production of chicory may also occur.
wild chicory can grow in the surroundings, but the GM chicory will be grown only during vegative phase, culture will be checked periodically to detect, and destroy, plants initiating flowering.
EN
No specific validated detection method available.

Additional information
The GM chicory possesses an extra SST enzyme that is expected to compensate for the decrease of activity of the native chicory SST. The result of this modification will be the accumulation in the GM chicory taproot of inulin with a higher mean DP. This alteration of the soluble carbohydrate content of the chicory root could have effect on different aspects of the life of the plants.
To avoid any effects, the GM chicory will be grown only during the vegetative part of their reproductive cycle and will not be allowed to flower.

Purpose of the release such as agronomic purposes, test of hybridisation, changed survivability or dissemination, test of effects on target or non-target organisms
The introduced enzyme is intended to sustain the endogenous chicory enzyme encoding the enzyme responsible for the first step  of the inulin biosynthesis.
This complementation is expected to result in an improved inulin quality. The purpose of the application is to assess under agronomic conditions the fructan production capacity of the transformed chicory and the effects of autumnal cold and frost on the quality of the inulin produced.
