In this review we describe the application of CRISPR tools for functional genomics screens in bacteria, with a focus on the use of interference (CRISPRi) approaches. We review recent developments in CRISPRi titration, which has enabled essential gene functional screens, and genome-scale pooled CRISPRi screens. We summarize progress toward enabling CRISPRi screens in non-model and pathogenic bacteria, including the development of new dCas9 variants. Taking into account the current state of the field, we provide a forward-looking analysis of CRISPRi strategies for determining gene function in bacteria.
在本综述中,我们描述了CRISPR工具在细菌功能基因组学筛选中的应用,重点是干扰(CRISPRi)方法的使用。我们回顾了CRISPRi滴定法的最新进展,该方法已实现了必需基因功能筛选和全基因组规模的CRISPRi筛选。我们总结了在非模式细菌和致病细菌中进行CRISPRi筛选方面取得的进展,包括新型dCas9变体的开发。考虑到该领域的现状,我们对用于确定细菌基因功能的CRISPRi策略进行了前瞻性分析。
