Abstract: Abstract: De novo DNA synthesis technologies refer to synthesizing DNA fragments from oligonucleotides. The improvement of DNA synthesis technologies is one of the reasons for the rapid development of synthetic biology. The traditional ligation-mediated DNA synthesis and PCR-mediated DNA synthesis are increasingly mature， and DNA can be synthesized in length of 0.5-1 kb in accuracy using these methods. Microarray-mediated DNA synthesis has recently attracted attention due to low cost and high throughput. The successful exploration of DNA synthesis in yeast provides a compensation method for synthesis in vitro. DNA synthesis has been applied widely， including codon optimization for heterologous expression， construction of heterogenous metabolic pathways， synthesis of artificial genomes， and synthesis of attenuated artificial virus for vaccine research. Here we summarized the research progress in de novo DNA synthesis methods and the advanced applications of DNA synthesis.
