Deciphering the Code of Pattern Formation: Integrating In Silico and Wet Lab Approaches in Synthetic Biology

Pattern formation is a fundamental process in biological development, enabling the transformation of initially uniform or random states into spatially ordered structures. A comprehensive understanding of the formation and function of these patterns is crucial for unraveling the underlying principles of biological design and engineering. In recent years, synthetic biology has emerged as a powerful discipline for investigating and manipulating pattern formation in biological systems, involving the design and construction of novel biological components, circuits, and networks with specific functionalities. The integration of computational simulations (in silico) and experimental techniques (wet lab) in synthetic biology has significantly advanced our knowledge of pattern formation and its implications in biological design and engineering. This review provides an overview of the computational simulations employed in studying pattern formation and introduces the representative and cutting-edge experimental methods utilized in wet labs.

Serine Integrase-based Recombination Enables Direct Plasmid Assembly In Vivo

Serine integrases are emerging as one of the powerful tools for synthetic biology. They have been widely developed across genome engineering, biological part construction, genetic circuit design, and in vitro DNA assembly. However, the strategy of in vivo DNA assembly by serine integrases has not yet been reported. To address this opportunity, here we developed a serine integrase-based in vivo DNA (plasmid) assembly approach. First, we demonstrated that the engineered “Acceptor” plasmids could be assembled with diverse “Donor” plasmids by serine integrases (Bxb1 and phiC31) in Escherichia coli (E. coli). Then, by programming the “Donor” plasmids and the host E. coli cells, we established an assembly cascade procedure and finally constructed plasmids that could constitutively express three different fluorescent proteins. Moreover, we used this approach to assemble different chromoprotein genes and generated colored E. coli cells. We anticipate that this approach will enrich the serine integrase-based biotechnology toolbox, and accelerate multiple plasmid assembly for synthetic biology with broad applications.
