Genetic manipulation of microorganisms has been crucial in understanding their biology, yet for many microbial species, robust tools for comprehensive genetic analysis were lacking until the advent of CRISPR-Cas-based gene editing techniques. In this Progress article, we discuss advances in CRISPR-based techniques for the genetic analysis of genetically intractable microorganisms, with an emphasis on mycobacteria, fungi and parasites. We discuss how CRISPR-based analyses in these organisms have enabled the discovery of novel gene functions, the investigation of genetic interaction networks and the identification of virulence factors.
遗传操作微生物在理解其生物学方面一直至关重要，但对于许多微生物物种来说，直到 CRISPR-Cas 为基础的基因编辑技术出现，才缺乏全面遗传分析的强大工具。在这篇进展文章中，我们讨论了基于 CRISPR 的技术在遗传上难以处理的微生物的遗传分析中的进展，重点是分枝杆菌、真菌和寄生虫。我们讨论了这些生物体中的基于 CRISPR 的分析如何能够发现新的基因功能，研究遗传相互作用网络以及鉴定毒力因子。
