Team:XMU-China/Description
Inspiration
As a famous saying goes, "Quantitative changes lead to qualitative changes". This year team XMU-China did experience a period of pain. During the brainstorming stage, our team was divided into 5 groups to explore different project directions for the 2019 iGEM competition. We initially constructed 5 alternative projects in 8 weeks:
1. Reuse of Waste Edible Oil: Efficiently Producing Surfactants in Bacillus Subtilis
2. Plasmid Delivery System Suppresses the Release of Inflammatory Cytokines in Inflammatory Bowel Disease (IBD) to Relieve Symptoms
3. Using Alkaloids to Kill Fouling Organism Barnacles
4. Repairing Wooden Buildings with E. coli Secreted Cellulose
5. Using Bacteria to Simulate Social Relationships
With these preliminary projects, we joined this year's Southern China Regional Meeting, and this meeting did help us determine our project's direction. During the brainstorming stage of our team, there was an idea that was promoting at that time: Using Alkaloids to Kill Fouling Organism Barnacles as mentioned above. This was surprisingly similar to the design introduced by Greatbay_SCIE in the meeting presentation. We had more in-depth communication with Greatbay_SCIE team for genetic circuit. As we hope to construct innovative project, this stimulated us to explore more new fields through brainstorming. The meeting was a great impetus for us to turn our attention to the study of sociology using synthetic biology.
Then we did a pointed literature search and summarized some ideas that could support this project.
Using microbes for sociology often gains interesting results. Japanese scientist Nakagaki (1) used slime molds to crack a maze successfully in 2004. In 2010, Tero (2) just spent 26 hours by using slime molds and sweet oat granules simulating the road map of Japanese Shinkansen which actually spent several decades to build. People wondered why slime molds without nervous systems can solve such complicated network problem in such a short time, but no wan can give a convincing answer so far. Shapiro (3) pointed out in 2007 that bacteria have cognitive, computational and evolutionary abilities. Meanwhile, they can utilize complex intercellular communication mechanisms to control the basic cellular biology functions of "advanced" plants and animals, which means that it is possible to use bacteria to simulate some basic social forms or interactions.
Bourke, an evolutionary biologist, gives an explanation for the biological evolution to social evolution. He believes that: genes form genomes, prokaryotic cells and protobacteria form eukaryote cells, eukaryote cells form multicelled organisms and multicelled organisms form eusocial societies or join with other organisms to form mutualisms. (4)
In fact, observing the evolution of a stable species to another stable species can better help us understand the social structure. However, due to the consideration of time cost, it seems to be a more viable way by using synthetic biological method to create engineering bacteria with different functions that we need directly.
So, we abstracted social relationships into Mutual Benefit, Altruism, Spite and Selfishness. Our team prepared to build genetic circuits around these 4 relationships.
But it was the origin version of our project, we lately improved our project for more than 4 times and finally formed the final version Re_Gone with the wind. You can see more details about why and how we updated the project version at the page of Integrated Human Practices.

Integrated Human Practices
This year’s Integrated Human Practices can be divided into four parts. Firstly, we have widely read sociological literatures on our project, which established the foundation for initially constructing our project. Additionally, we have communicated with professors from Molecular Anthropology, Bioenergy Engineering, Sociology and Public Affairs Management respectively, whose feedbacks helped us to determine the subject of our project and the major direction of the experiment design. What’s more, in terms of the details of the subject, we have made an elaborate design for the questionnaire using social-science research methods, and we have conducted extensive investigations in iGEM Community and public. We attended various exchange meetings in China, and communicated with many teams.
