At present, with the development of genetic engineering techniques and continuous reduction in gene sequencing costs, some micrcalgal genomes have been successively published, which enables specific genetic modification of microalgae according to human＇s demand and provides broad application prospects. In this paper, different mediating systems and emerging genome editing techniques were summarized, which laid the foundation for the application of genetic engineering methods for microalgae.展开更多
