Project / Concept

Since 2007, 17 teams from 8 different countries have already chosen the problem of heavy metals in our environment as their topic. A total of 13 medals have been awarded in this subject area. This shows how relevant and highly topical the subject is. While other teams have concentrated more on detection and quantification, we want to go one step further with our concept of plant-based water and soil decontamination. Here you find more Background about heavy metals...

With our project we combine cleaning nature by using nature itself: We want to equip plants with a protein which binds four different heavy metals at the same time and hence brings about a significant reduction in the heavy metal concentration of grounds and seas. We thus hope to achieve more extensive binding of hazardous heavy metals than that achieved by conventional methods.

1. step: Transformation of Plants 2. step: Secretion and Immobilising 3. step: Water and soil decontamination

Our path to finding a solution

We created a protein for binding heavy metals that is intended to be expressed and produced in plants. This protein, called Top4-Metal-Binding-Protein (T4-MBP), contains 4 different domains of methallothioneins. Each domains is specific for a different heavy metal: Copper, Arsenic, Zinc and Cadmium. To avoid cytotoxic effects on the plant caused by the heavy metals we decided to put T4-MBP out of the cell. With a secretion signal (Expa4) the T4-MBP is directed to the extracellular space. Via the cellulose binding domain the protein is attached to the cell wall. The transformation of the T4-MBP is done via the binary vector pORE-E3 in which we exchanged the promoter and completed it with an optimized 5'UTR. Here you find more about our construct...

We decided to demonstrate the principle initially in the model organisms Arabidopsis thaliana (A. thaliana) and Nicotiana tabacum (N. tabacum) with the aid of a transformation by Rhizobium radiobacter (formerly Agrobacterium tumefaciens). For what reason...?
