The Story of Prometheus
We are iGEMers from BNU-China, we are going to tell you a story about E.coli Prometheus ...
2
Mr E.coli Prometheus is a philanthropic man. One day, he saw plenty poor peanuts living in a condition that was rough for them to grow up nor to flower. He made up his mind that he must to do something to help!
3
Then he found us for help, he asked for the power to collect molybdate and send them to peanut. We told him: " Since the power is not belong to you in nature, for the sake of the other life, you will die after this." But he didn't change his mind for one second.
4
E.coli Prometheus collected many molybdate with the power ...
5
He sent the precious micronutrient to those peanut everyday. The peanuts became more and more healthier and was about to flower ...
4
Sadly, E.coli Prometheus flied to heaven before he saw the flowers of peanut. He died as we informed him before. His body changed into nutrition for peanut after his death.
     He is honorable.
THE STORY OF E.COLI PROMETHEUS

Our work

The ability of rhizobium to fix nitrogen is essential for legumes growth and development. The stronger the ability, the less chemical fertilizer will be used. Molybdenum is a key element in rhizobial nitrogen fixing enzyme, and is also necessary for the growth of plants themselves. However, Mo being heavy mental, abusing it will pollute the environment. Hence, spot application of Mo is of great importance; it would be even better to concentrate the element only around the roots.

We transferred our designed plasmids into E.coli "Prometheus" to make it express a fusion protein: one half of it anchors on the outter membrane and the other side, namely ModA, absorbs molybdate. With the help of organic acid chemotaxis system, our "Prometheus" will head for the roots. A suicide system depending on time is also designed for bio-safety concerns. E.coli Prometheus will deliver Mo directly to the root. This opens a new chapter of biological fertilizer.




Wiki Design

Art design, pictures, figures and the latest experiment results were put on the wiki, an important platform to show our works.


ModA & INPN

ModA we used in our project can bind the molybdate, and INPN can display ModA on E.coli surface.


Chemotaxis

We Used McfR plasmid to give E.coli the capacity of Chemotaxis, so that those E.coli carrying molybdate can "swim" to the root of peanut.


Modeling

We have made a model of peanut roots and E.coli in surrounding environment to simulate our idea in soil.
