            <p class="abstract__text">We focused on establishing a framework to implement genetic manipulation techniques—specifically, multiplex automated genome engineering (MAGE) and CRISPR-Cas9 systems—into non-model, environmentally significant microbes using standard biological parts. The framework involves two components: (1) propagation and selection of cultures and (2) manipulation of cell genomes by MAGE and/or CRISPR. We identified design considerations for both components of the framework, and experimentally validated propagation and selection considerations using cyanobacterial strain Synechococcus sp. PCC 7002 (a fast-growing cyanobacterium capable of lipid biofuel production) and Rhizobium tropici CIAT (a nitrogen-fixing rhizobium which forms root nodules in legume plants). We then developed a workflow for the design, construction, and testing of MAGE and CRISPR technologies into non-model prokaryotes. The insights we gained from validating the propagation component of our workflow will serve to improve the versatility and robustness of our framework and will inform the development of tools for genetic manipulation in other non-model organisms.</p>

Not your typical role model. Learn more.

Design

By talking about your design work on this page, there is one medal criterion that you can attempt to meet, and one award that you can apply for. If your team is going for a gold medal by building a functional prototype, you should tell us what you did on this page. If you are going for the Applied Design award, you should also complete this page and tell us what you did.

Project Design

Our project focused on developing methods to tame non-model organisms and develop them for genetic manipulation. We chose for this project Cyanobacterium and Rhizobium because we foresee their successful applications in the fields of biotechnology. Cyanobacteria can become a producer of biofuel driven by light energy and Rhizobium can cultivate the soil and control the spread of genetically modified crops.

Grow

We succeeded in growing the strains and developing a robust assay for testing growth of non-model organisms in various media. We were informed by literature and work previously done in growing these particular microbes.

Transform

We were able to transform our non-model organisms and express our heterogenous DNA. Transformation is an integral part of synthetic biology and so we spent significant effort trying multiple protocols until we arrived at one with acceptable efficiency

Select

After transformation, selection was a key step. By modifying existing protocols testing for antibiotic resistance, we were able to develop a robust assay for antibiotic resistance and susceptibility in non-model organisms. This was a key step in pushing forward in taming non-model organisms.

MAGE

Multiplex automated genome engineering (MAGE) and recombineering are genetic manipulations techniques now used in E. coli, but that would make ideal techniques for use in our non-model organisms. In order to establish these in our organisms we searched through the body of research currently in existence and pulled out potentially useful recombinase proteins. We developed an assay to test for the activity of our recombinases as well.

Taming the Model Organism

Establishing genetic manipulation techniques and standard practice for these non-model organisms would have been the absolute success for our project. Thus far we have determined how to grow, transform, select, and integrate important elements of genetic manipulation systems into our organisms. More importantly, we have developed assays and principles that can be applied to the taming of any non-model organism.
