摘要
Cell factories can use microbial cells to produce the energy, drugs, and chemicals that humans need. The adaptation of chassis cells to exogenous metabolic pathways is a core challenge in building efficient cell factories. Genome synthesis refers to the bottom-up construction of a genome from chemically synthesized nucleotides. Genomic induced rearrangement refers to the customized regulation of DNA sequences and structures in genome scale. Genome synthesis and inducible rearrangement have enabled the creation of organisms, enhanced the flexibility of model chassis. Proper genome simplification and codon simplification improve the utilization efficiency of substrates and energy, and improve the predictability and controllability of cell physiological performance. Genomic rearrangement can generate structural variations such as random deletion, replication, translocation and inversion. The rearrangements of synthetic genome accelerate the rapid evolution of chassis and the optimization of metabolic pathways, and improve the adaptability between chassis and pathway. The genome synthesis and inducible rearrangement provide a new strategy for the construction and optimization of cell factories. © All Right Reserved.
