Recruitment: We Want You!

As everyone comes back after the summer break, we begin recruiting new 2018 Team MOD members. The handover process from 2017 iGEM Team SECA means we're slowly building an iGEM alumni here at UoA. They've been really helpful mentoring us as we start our new project in terms of sharing research documentation, transferring financial accounts, and having a small team cheering for us from the sidelines.

Fundraising

Had a meeting with Alastair Harris (Alumni from iGEM 2017) to organise financial accounts with our partner, Chiasma (Turns out Jessica Chiang, an Alumni from iGEM 2016, is CEO of Chiasma now so that’s handy). We talked about almost everything to do with iGEM and the Giant Jamboree, including presenting to Chiasma for constructive feedback. Contacted Shaun Lott to confirm the rollover of some more funding from Return on Science.

Registering Our Team

Began the iGEM team registration process, however problems with transferring bank account authority prevented us from paying iGEM (we therefore missed the early registrations). Confirmed primary lab space with Austen Ganley and secondary lab space with Jo Putterill if we need to do work on a plant model. Completed the iGEM Resource Description form. Nearly finished sorting out our financial account - thanks to iGEM alumni Jessica Chiang and Sheree Clifton from Chiasma (one of our university partners).

Contacted Matthew Mayo-Smith, a summer lab student recommended by our PI, Jo Putterill, due to his knowledge of plant molecular methods. Matthew was unsure whether he’d be at Auckland Uni this year but is keen to help if needed.

Improving the Wiki System

Followed up with Suzie and Traci from iGEM HQ about improving their wiki-handin system. They were well impressed with our website initiative but are having trouble implementing changes. We’re giving it one last push and offering all the help we can! The goal here is to allow teams to submit both a wiki and a private website to allow best practice web design and development for students.

Identifying a National Problem

As a team we've all come together to discuss potential project ideas. Everyone has their own specific interests ranging from plant physiology to wine microbiology - it's great to see a diverse range of options. We've identified waterway pollution as a huge problem in New Zealand: each year we're seeing more incidences of toxic algal bloom formation in the summer and have begun searching potential ways to use synthetic biology to combat this issue.

Donec ac mauris nulla. Nam eu purus sed turpis congue placerat. Nunc ut lorem eu arcu auctor sollicitudin.

Refining our Biological Solution

After carrying out our own research, we've looked into the effects of dairy run-off entering the water system. Discussion with our PI and researchers within the university has helped narrow down the chosen metabolic pathway we might upregulate. We've chosen Arabidopsis thaliana as our model organism and plan on increasing the uptake and breakdown of excess urea in the soil.

Set up a meeting with Dr Nijat Imin who specialises in nitrogen activity in plants. We were already thinking of upregulating AtDUR3 urea transporter and incorporating H. pylori’s urease that has a high affinity. He's informed us that ammonia is toxic in high amounts and gave us a few transporters that would be able to redirect it to other parts of the plant. He is excited about the project and is willing to give us more support throughout the year.

Lab induction time! We've all had to complete our safety training so we can jump into the PC1 facilities for our lab work.

Looking Beyond the Lab

If we're looking at a product for dairy farmers, it's important to start thinking about market validation. Rachel has begun speaking to social scientists in the university to get an idea of how to conduct a focus group, and how to engage with students as part of our community engagement efforts.

Identifying the Urea Metabolic Pathway

The team met with Nijat again after researching further into his suggestions. H. pylori high affinity urease will be a bit difficult to introduce as it would need special approval to be inserted into A. thaliana. It's also a human pathogen and has a different accessory proteins (so it's very complicated!). We need to look into another way of upregulating urease.

We’ve decided that we want to upregulate the AtDUR3 gene then the urease or rate limiting accessory protein. There is limited research around upregulating urease activity: one of the urease accessory proteins, UreG, might be our best luck as an alternative to expressing urease + all accessory genes.

Rachel has been researching which glutamine synthetase gene we might upregulate. GS1;2 isogene appears to be the most successful in producing glutamate from ammonia at the highest capacity.

Sharing our Experiences with Synthetic Biology

Hadleigh, Prokhor, Greta and Sneha went to St. John’s School in Mairangi Bay to teach our first lesson for the community engagement project. We taught two classes of Year 6 students how to conduct a basic scientific experiment and gave them the task of coming up with their own solutions to the polluted waterways issue. We then introduced GM and the concept of DNA to them - they asked a lot of questions!

For Team MOD, experiences like this really put our work into perspective. We want to share the potential we see in GMOs with the rest of New Zealand - this can happen at any level, from the big guys up in parliament to kids in the classroom.

Thinking about our Business Model

Spent the entire week working towards our Return on Science presentation, really diving into the commercial aspects of our project and thinking about GMO policy in New Zealand which is exciting! We’ve also spoken to our secondary PI, Shaun Lott, about the future of iGEM in terms of next year’s team and getting recognition from the university as a contribution to the BSc degree.

Getting started with our BioBrick Characterisation

Early June: Had a meeting with 2017 iGEM team lab members, Judith and Jess, to get a better idea of how we can work more efficiently. They suggested not to continue from their BioBrick project this year, but instead do a fluorescent or chromoprotein. We've chosen BBa_E0020 from 2004 - we’ll be finding out at what pH we observe the highest fluorescent intensity.

We've met with our lab supervisor, Jasper, to go over our lab protocol and familiarise ourselves to the BioBrick standard system.

Mid-June: Finally jumping into the lab to do our plating and preparatory steps for the transformation into competent E. coli strain, DH5α. We’re all starting to feel the pressure of upcoming exams which is getting in the way of lab progress. Right now, the priority is to grow our transformed E. coli and get them on ice so we can experiment on them later in July.

Our first transformation of our BioBrick has been successful! We’re now waiting for our primers (from our IDT free DNA supply) to arrive in the mail so we can run colony PCR and confirm our insert is being expressed.

Designing our Urea Gene Constructs

We’re starting to design our GS1;2 construct to transform into Agrobacterium, with help of our PI and other researchers, Nijat Imin and Matthew Mayo-Smith. We plan on using the Gateway reaction (using the attB sites) to introduce our gene constructs into our chosen destination vectors. From their advice, we'll be using pDONR221 as our entry vector and pB2GW7 as our destination vector.

The UreG plasmid the plant lab ordered from another lab group arrived in the mail. We want to test our Gateway protocol as we wait for our IDT vectors to arrive, but first we need to find out how to add the attB sites to our plasmid.

Working through the BioBrick lab

Early-July: Received our BioBrick primers from IDT and will begin the characterisation part of our project. It would be a good idea for future iGEM teams to provide primers for the BioBrick standard in the Distribution Kit. We’re also contacting past iGEM teams that have contributed to the same BioBrick or used similar protocols that we plan on using.

Mid-July: We’ve run into some roadblocks in the BioBrick characterisation lab - spending the week troubleshooting our PCR protocol. We’ve found the polymerase we’ve been using hasn’t been that efficient, now using KAPA2G. Also looking at the BioBrick construct, our original Brick (BBa_E0020) doesn’t have a promoter so there’s no way to observe CFP expression unless we subclone it into another vector - (this seems like poor design in terms of iGEM’s standard system). For this reason we’ve switched to characterising the RFP in the composite BBa_I3241 Brick.

We’ve successfully transformed our composite RFP BioBrick into E. coli and run colony PCR to confirm. We’ll be spending the rest of the week planning our purification technique (subcloning into another vector to add a HisTag) and fluorescent characterisation under different salinities. We’ve found the transformed E. coli grow a bit slower than usual - I’ve sent out emails asking past teams that have worked with our BioBrick if they’ve encountered the same problems. Still waiting for them to reply!

Starting our Investor Presentations!

Presented our research to BioMatters! They were really receptive towards our idea in terms of it being relevant to nitrogen pollution in New Zealand. Such a cool experience connecting with people in the industry who are equally passionate about GMOs and are keen to support us!

Had our presentation with Return On Science! It’s cool to see our lab students present the entrepreneurial aspects of our project for the first time. We got some good feedback on areas of commercialization we should deeper look into - particularly around IP and our business model.

Expanding the iGEM Community

One of our contribution initiatives is to establish another iGEM team in New Zealand. We've spoken to Kyle Webster, a PhD student previously from Canterbury University, who was involved in our past iGEM teams here in Auckland. He's keen to help us get in contact with the right people in Canterbury University to spread this opportunity to other undergrads down in the South Island.
