<p class="texte">Since the birth of humanity, man himself understood well the importance of studying and mastering Nature to develop the civilization. Still today the most advanced technologies often try to mimic natural phenomena. With the development of the civilizations, men modified their environment, changing it for their own comfort depending on their own desire. By increasing their cities and acitvities, humans modify the natural environment. With the industrialization of the societies, the natural environment has suffered from human activities such as waste discharges, oil slicks, intensive fishing but also the introduction of devastating species such as the pathogen,<I> Ceratocystis platani</I>. However, despite these negative aspects, men are capable of favorable actions to help the environment and fix their mistakes. The current trend is to limit the impact of human interventions on the nature, and hopefully this trend is not transient and will not vanish. A new desire is born, a wish to protect the nature and the wildness. Man fits with his position: he takes advantage of the environment and the environment takes advantage of the reasoned human interventions. There is an adaptation of the mankind toward the nature. Moreover, humans have the capacity of empathy: people are able to understand the emotions and cognitive states of other organisms and to identify to them. To respond to these feelings, humans have technological tools allowing them to fight against enemies such as <I>Ceratocystis platani.</I>

<p class="texte">One single tree infected by the canker, that is a perimeter of a couple of hundred meters which is included in the prophylactic cut. So there a healthy population in this area, we want to protect this tree. There is a common principle in agronomics that said that you prefer to save the population to the subject. According to this concept the introduction of our GEM seems acceptable. A result of the subtitree’s introduction is the modification of endophytic microbial fauna, but without any treatment organisation of the entire population will be messier. As subtitree is an annual bacterium, its side effect will not last in the time, this disruption in this balance will return to the normal. </p>

<p class="texte">One single tree
 +
infected by Canker, and all the trees located in an area of a couple of hundred
 +
meters around are included in the prophylactic cut. We acted to preserve the
 +
surrounding trees. The modification of the endophytic
 +
microbial fauna generated by the introduction of the engineered bacterium has
 +
to be compared to the introduction of chemicals. They contain chlorine atom and
 +
aromatic hydrocarbon, so their remediation is complicated and they represent a
 +
source of pollution. By shortening the lifespan to one season and minimizing
 +
the risks of spreading, we plan a safe and environmental-friendly way to fight

Canker.

<p class="texte">Furthermore, usual fungicides used come from chemical industry. They contain chlorine atom and aromatic hydrocarbon, so their remediation is complicated and they represent a source of pollution. We propose to use in this project biofungicide, so they are eco-friendly and more specific. Thus they seem to be a good way to fight against the fungal infection.  </p>

deeper. First, we can improve the fixation module. Using chitin as fixation

anchor is simple but not enough specific to fix just one fungus type. That’s

why we first think to fix SubtiTree to one protein

included in the <i>Ceratocystis
