<h4>Tips</h4>
+
−
<p>This wiki will be your team’s first interaction with the rest of the world, so here are a few tips to help you get started: </p>
+
−
<ul>
+
−
<li>State your accomplishments! Tell people what you have achieved from the start. </li>
+
−
<li>Be clear about what you are doing and how you plan to do this.</li>
+
−
<li>You have a global audience! Consider the different backgrounds that your users come from.</li>
+
−
<li>Make sure information is easy to find; nothing should be more than 3 clicks away.  </li>
+
−
<li>Avoid using very small fonts and low contrast colors; information should be easy to read.  </li>
+
−
<li>Start documenting your project as early as possible; don’t leave anything to the last minute before the Wiki Freeze. For a complete list of deadlines visit the <a href="https://2015.igem.org/Calendar_of_Events">iGEM 2015 calendar</a> </li>

<h4> Uploading pictures and files </h4>
+
−
<p> You can upload your pictures and files to the iGEM 2015 server. Remember to keep all your pictures and files within your team's namespace or at least include your team's name in the file name. <br />
+
−
When you upload, set the "Destination Filename" to <code>Team:YourOfficialTeamName/NameOfFile.jpg</code>. (If you don't do this, someone else might upload a different file with the same "Destination Filename", and your file would be erased!)</p>

IGEM Bordeaux 2015

IGEM Bordeaux 2015

Cur'd Vine


Problem

We all love wine , right?

France is the first producers and exporters of wine, representing approximately 16% of the world's production. In fact, Aquitaine is one of the 4 regions which produces the most wine. However, vineyards are threatened by an oomycete called Plasmopara viticola , otherwise known as Downy Mildew which affects the quality of wine by causing irreparable damages to grapevine organs. This microorganism infects the grapevine’s tissues, particularly it's leaves, draining the plant’s resources and preventing its photosynthetic capacities.

The most common preventive treatment used by vineyards in the region is called « bouillie bordelaise » and is composed of copper sulfate , a product which has toxic effects on the surrounding soil. Although this treatment is efficient and does help to protect the plant from harmful microorganisms, this method has a bad environmental and sanitary impact since the copper present in the treatment infiltrates in the ground and prevents the growth of other types of plants, therefore impacting the biodiversity of the region. Furthermore, long term contact with these chemical components can create symptoms such as headaches, stomachaches, or renal/hepatic dysfunctions for those living in these contaminated areas.

To sum it up

We plan on using two host organisms: Sacharomyces cerevisiae which naturally produces Curdlan and Escherichia coli , the most common organism used for synthetic biology. Our genes will be synthethized industrially by IDT and will be inserted respectively in Saccharomyces cerevisiae or Escherichia coli with their appropriate promoters. These modified cells will then be cultivated to produce our Curdlan molecule in large quantities. The final step of our project will be to extract the curdlan molecule, to quantify our production and to sulfate the molecules if possible.

Solution

This year, iGEM Bordeaux proposes an eco-friendly alternative treatment to prevent Downy Mildew: replacing copper sulfate by Curdlan , a sugar biopolymer which stimulates the plant's immune system . But what does that mean?
Actually, the plant naturally defends itself against pathogens through two distinct levels of immunity, a specific and non specific imunity which both cause a depolarization of the infected cell membrane and triggers the production of antimicrobial metabolites. Curdlan is recognised by the non specific immune system and activates it, with mechanisms similar to modern day vaccines.
The production of our molecule will be done using non-pathogenic micro-organisms which can easily be grown in our lab: Escherichia coli and Saccharomyces cerevisiae . These are two microorganisms commonly used in synthetic biology and that are amongst the most well known organisms on the planet.

Team members

Who is going to do all of this you ask?
Well, this year's iGEM Bordeaux's team is made up of 23 devoted students from diverse backgrounds. Whether we be from the Bordeaux University, from a biotech engineering school or from a Science Engineering school, we are all united for this unique project and are willing to give it our all to make it succeed!
In order to do so, we united our scientific knowledge and contacted various researchers to put together our protocols. At the same time, our team has spent time and energy thinking about various non-scientific aspects of our project including how to popularize scientific knowledge to raise awareness on the possibilities of synthetic biology. We have also considered throughout the project ethical and bio-safety thematics in order to insure that our protocols are not hazardous for the environment and that any genetically engineered microorganism is controled within the lab.

Sponsors


On behalf of the entire team, we would like to thank our sponsors for allowing us to build this project and present it at the 2015 edition of the Internationnal Genetically Engineered Machine competition! Also we would like to thank our donators!
