The field of synthetic biology continues to develop rapidly, amalgamating innovations in genome biology and data science with basic principles of engineering. Researchers are able to manipulate increasingly complex genomes and organisms using new technologies and techniques, such as introducing customizable synthetic genomes into eukaryotic organisms. New functions and metabolic pathways, which did not previously exist in nature, can now be designed and built into organisms using gene- and genome-editing technologies, and high-throughput engineering and testing approaches are being used to generate new microbial strains with recoded genomes. These technologies are also enabling the study and manipulation of microbial communities within their environments.
Advance fundamental understanding of genome biology and develop the genome-scale engineering technologies needed to design, build, and control plants and microbes for desired beneficial purposes.
The ability to deliberately manipulate and design biological systems has large implications for Genomic Science Program (GSP) research, including the elucidation of gene function at the organismal level; production of novel, high-value fuels, chemicals, and materials; and manipulation of plant and microbial behavior and interactions for the development of sustainable biofuel and bioproduct production systems. The program seeks to enable a future in which biological systems can be designed for specific purposes in silico and be built and tested using automated procedures, delivering new biosystems for deployment into the bioeconomy. Given the complexity and breadth of the requisite scientific challenges, this goal will require a broad, interdisciplinary, and cross-institutional approach.
GSP therefore recognizes that novel approaches to organizing scientific interactions and collaborations, such as virtual laboratories, may offer significant advantages. The program will also work to leverage the many synergies of current biosystems design developments with other Biological and Environmental Research (BER) program elements into a diverse research portfolio in biological engineering. As the promise of synthetic biology begins to bear fruit, the biotechnology industry is expected to play a growing role in the U.S. economy. BER is poised to contribute to growing opportunities in this area through its support of basic biosystems design research relevant to DOE’s mission space.Broadly, GSP biosystems design research objectives seek to:
- Discover and develop novel platform organisms across a range of physiologies as chassis for synthetic biology.
- Develop innovative genome-engineering tools, including large-scale DNA synthesis and intracellular delivery, recoded and minimal genomes, orthogonal pathways, and cell-free systems.
- Develop high-throughput genome editing, automated screening, characterization, phenotyping, and testing of engineered organisms.
- Elucidate gene function at the genome scale to develop generalized approaches for biological engineering.
- Provide computer-aided design tools, including artificial intelligence and machine-learning techniques, in an integrated, open-access platform for plants and microbes as part of an in silico or virtual laboratory capability.
- Develop analytical and characterization tools to understand processes of organic and inorganic synthesis and degradation in engineered organisms.
- Elucidate mechanisms for the acquisition, storage, transport, and chemical transformation of substrates in engineered organisms.
- Support research to build new genetic, regulatory, and biosynthetic networks to biologically produce useful molecules and materials that may or may not exist in nature.
- Develop new approaches for novel macromolecular design, characterization, and testing.
- Expand the “design-build-test-learn” cycle to organismal consortia.
