Construction and iterative redesign of synXVI a 903 kb synthetic Saccharomyces cerevisiae chromosome.

The Sc2.0 global consortium to design and construct a synthetic genome based on the Saccharomyces cerevisiae genome commenced in 2006, comprising 16 synthetic chromosomes and a new-to-nature tRNA neochromosome. In this paper we describe assembly and debugging of the 902,994-bp synthetic Saccharomyces cerevisiae chromosome synXVI of the Sc2.

Killer yeasts: expanding frontiers in the age of synthetic biology.

Killer yeasts secrete protein toxins that are selectively lethal to other yeast and filamentous fungi. These exhibit exceptional genetic and functional diversity, and have several biotechnological applications. However, despite decades of research, several limitations hinder their widespread adoption.

Engineering biology and climate change mitigation: Policy considerations.

Engineering biology (EngBio) is a dynamic field that uses gene editing, synthesis, assembly, and engineering to design new or modified biological systems. EngBio applications could make a significant contribution to achieving net zero greenhouse gas emissions. Yet, policy support will be needed if EngBio is to fulfil its climate mitigation potential.

Parallel laboratory evolution and rational debugging reveal genomic plasticity to synthetic chromosome XIV defects.

Synthetic chromosome engineering is a complex process due to the need to identify and repair growth defects and deal with combinatorial gene essentiality when rearranging chromosomes. To alleviate these issues, we have demonstrated novel approaches for repairing and rearranging synthetic genomes. We have designed, constructed, and restored wild-type fitness to a synthetic 753,096-bp version of chromosome XIV as part of the Synthetic Yeast Genome project.

A spotlight on global collaboration in the Sc2.0 yeast consortium.

The Synthetic Yeast Genome Project (Sc2.0) is an international collaboration that aims to create and optimize synthetic versions of each chromosome, with the ultimate goal of assembling a yeast organism with a synthetic with design features facilitating applications in synthetic biology and engineering projects. The consortium research groups are global, and, here, we highlight the work of the China-based Sc2.
