<p>Pathogens belonging to the Fursarium species are known to infect a wide range of crops and cause large losses in agriculture. In this project, we will concentrate on protecting bananas from Fusarium oxysporum f.sp. cubense using an engineered strain of the native soil bacterium Pseudomonas putida. At present commercially grown bananas for export are all the same species, known as Cavendish. Prior to the 1960s, though, the Gros Michel cultivar was the primary banana for export. This species was almost completely wiped out within a decade by the Panama disease that is caused by Fusarium. Recently a new strain of Fusarium has been infecting Cavendish plants and is spreading throughout the world.</p>

<h1><b>Saving the bananas</b></h1>
 +
 +
<p> Every time you go to the supermarket or to the local market to buy bananas you take for granted that there will be bananas readily available for you to enjoy and savour. However, banana plants are under threat and a world without bananas is more plausible than we all might imagine. Banana plants are threatened by <i>Fusarium oxysporum</i>. This pathogenic soil fungus enters plants through their root systems and lives off of them until they die. This fungus currently threatens all banana plants worldwide. Bananas, apart from being a delicious fruit, have economic importance in many tropical regions and are an important part of the diet. These are the reasons why the <b>iGEM team Wageningen 2014</b> has designed and created BananaGuard, a genetic system in <i>Pseudomonas putida</i> that detects the presence of <i>F. oxysporum</i> in the soil and produces a combination of antifungals to remove the fungal threat. If you want to read more about the system and our work during the last six months, the <b>iGEM team Wageningen 2014</b> invites you to continue surfing around our Wiki.</p>

<p>The first and perhaps most important part is the production of fungal growth inhibitors. In order to prevent these fungal inhibitors from damaging the soil microbiome, their production will be coupled to the sensing of fusaric acid, a characteristic toxin produced by Fusarium. To help our host compete against the fungus, resistance against fusaric acid will also be incorporated.</p>

<p>Protecting the natural biodiversity is a big part of our project. When the Fusarium threat has been detected and subsequently cleaned up, the bacteria will activate a kill-switch. In addition to this, spread of the genetically modified material will be prevented by a double dependent plasmid system in which loss or gain of one of the two modified plasmids will cause the host to kill itself.</p>

Bananas, apart from being a delicious fruit, have economic importance in many tropical regions and are an important part of the diet.
