Harnessing stepping-stone hosts to engineer, select, and reboot synthetic bacteriophages in one pot. CELL REPORTS METHODS 2022; 2:100217. [PMID: 35637913 PMCID: PMC9142689 DOI: 10.1016/j.crmeth.2022.100217] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/03/2021] [Revised: 03/07/2022] [Accepted: 04/25/2022] [Indexed: 11/24/2022]
Abstract
Advances in synthetic genomics have led to a great demand for genetic manipulation. Trimming any process to simplify and accelerate streamlining of genetic code into life holds great promise for synthesizing and studying organisms. Here, we develop a simple but powerful stepping-stone strategy to promote genome refactoring of viruses in one pot, validated by successful cross-genus and cross-order rebooting of 90 phages infecting 4 orders of popular pathogens. Genomic sequencing suggests that rebooting outcome is associated with gene number and DNA polymerase availability within phage genomes. We integrate recombineering, screening, and rebooting processes in one pot and demonstrate genome assembly and genome editing of phages by stepping-stone hosts in an efficient and economic manner. Under this framework, in vitro assembly, yeast-based assembly, or genetic manipulation of native hosts are not required. As additional stepping-stone hosts are being developed, this framework will open doors for synthetic phages targeting more pathogens and commensals.

Abstract
Heterologous pathways are linked series of biochemical reactions occurring in a host organism after the introduction of foreign genes. Incorporation of metabolic pathways into host organisms is a major strategy used to increase the production of valuable secondary metabolites. Unfortunately, simple introduction of the pathway genes into the heterologous host in most cases does not result in successful heterologous expression. Extensive modification of heterologous genes and the corresponding enzymes on many different levels is required to achieve high target metabolite production rates. This review summarizes the essential techniques used to create heterologous biochemical pathways, with a focus on the key challenges arising in the process and the major strategies for overcoming them.

Rabinowitch I. What would a synthetic connectome look like? Phys Life Rev 2019; 33:1-15.

Abstract
A major challenge of contemporary neuroscience is to unravel the structure of the connectome, the ensemble of neural connections that link between different functional units of the brain, and to reveal how this structure relates to brain function. This thriving area of research largely follows the general tradition in biology of reverse-engineering, which consists of first observing and characterizing a biological system or process, and then deconstructing it into its fundamental building blocks in order to infer its modes of operation. However, a complementary form of biology has emerged, synthetic biology, which emphasizes construction-based forward-engineering. The synthetic biology approach comprises the assembly of new biological systems out of elementary biological parts. The rationale is that the act of building a system can be a powerful method for gaining deep understanding of how that system works. As the fields of connectomics and synthetic biology are independently growing, I propose to consider the benefits of combining the two, to create synthetic connectomics, a new form of neuroscience and a new form of synthetic biology. The goal of synthetic connectomics would be to artificially design and construct the connectomes of live behaving organisms. Synthetic connectomics could serve as a unifying platform for unraveling the complexities of brain operation and perhaps also for generating new forms of artificial life, and, in general, could provide a valuable opportunity for empirically exploring theoretical predictions about network function. What would a synthetic connectome look like? What purposes would it serve? How could it be constructed? This review delineates the novel notion of a synthetic connectome and aims to lay out the initial steps towards its implementation, contemplating its impact on science and society.

Whole genome engineering by synthesis. SCIENCE CHINA-LIFE SCIENCES 2018; 61:1515-1527. [PMID: 30465231 DOI: 10.1007/s11427-018-9403-y] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/20/2018] [Accepted: 08/31/2018] [Indexed: 01/12/2023]
Abstract
Whole genome engineering is now feasible with the aid of genome editing and synthesis tools. Synthesizing a genome from scratch allows modifications of the genomic structure and function to an extent that was hitherto not possible, which will finally lead to new insights into the basic principles of life and enable valuable applications. With several recent genome synthesis projects as examples, the technical details to synthesize a genome and applications of synthetic genome are addressed in this perspective. A series of ongoing or future synthetic genomics projects, including the different genomes to be synthesized in GP-write, synthetic minimal genome, massively recoded genome, chimeric genome and synthetic genome with expanded genetic alphabet, are also discussed here with a special focus on theoretical and technical impediments in the design and synthesis process. Synthetic genomics will become a commonplace to engineer pathways and genomes according to arbitrary sets of design principles with the development of high-efficient, low-cost genome synthesis and assembly technologies.
