酿酒酵母基因编辑技术研究进展

Progress in gene editing technologies for Saccharomyces cerevisiae

酿酒酵母Saccharomyces cerevisiae是代谢工程中最重要的宿主之一,先进的基因编辑技术已经被广泛应用于酿酒酵母细胞工厂的设计和构建。随着基因编辑技术的飞速发展,早期基于重组酶和同源重组的基因编辑技术逐渐被新型基因编辑系统所替代。文中对酿酒酵母基因编辑技术的原理和应用进行了总结,包括经典的酿酒酵母基因编辑技术,基于核酸内切酶的MegNs、ZFNs和TALENs等基因组编辑系统,最后介绍和讨论了基于CRISPR/Cas系统、异源代谢途径多拷贝整合和基因组规模基因编辑的最新研究进展,并对酿酒酵母基因编辑技术的应用前景和发展方向进行了展望。

Saccharomyces cerevisiae is one of the most important hosts in metabolic engineering.Advanced gene editing technology has been widely used in the design and construction of S.cerevisiae cell factories.With the rapid development of gene editing technology,early gene editing technologies based on recombinase and homologous recombination have been gradually replaced by new editing systems.In this review,the principle and application of gene editing technology in S.cerevisiae are summarized.Here,we first briefly describe the classical gene editing techniques of S.cerevisiae.Then elaborate the genome editing system of MegNs,ZFNs and TALENs based on endonuclease.The latest research progress is especially introduced and discussed,including the CRISPR/Cas system,multi-copy integration of heterologous metabolic pathways,and genome-scale gene editing.Finally,we envisage the application prospects and development directions of Saccharomyces cerevisiae gene editing technology.
