title: An improved method of gene synthesis based on DNA works software and overlap extension PCR.
abstract: A bottleneck in recent gene synthesis technologies is the high cost of oligonucleotide synthesis and post-synthesis sequencing. In this article, a simple and rapid method for low-cost gene synthesis technology was developed based on DNAWorks program and an improved single-step overlap extension PCR (OE-PCR). This method enables any DNA sequence to be synthesized with few errors, then any mutated sites could be corrected by site-specific mutagenesis technology or PCR amplification-assembly method, which can amplify different DNA fragments of target gene followed by assembly into an entire gene through their overlapped region. Eventually, full-length DNA sequence without error was obtained via this novel method. Our method is simple, rapid and low-cost, and also easily amenable to automation based on a DNAWorks design program and defined set of OE-PCR reaction conditions suitable for different genes. Using this method, several genes including Manganese peroxidase gene (Mnp) of Phanerochaete chrysosporium (P. chrysosporium), Laccase gene (Lac) of Trametes versicolor (T. versicolor) and Cip1 peroxidase gene (cip 1) of Coprinus cinereus (C. cinereus) with sizes ranging from 1.0 kb to 1.5 kb have been synthesized successfully.
