I型CRISPR-Cas系统是细菌的最丰富和最广泛的适应性免疫系统,并且可以在温和噬菌体感染的情况下极大地增强细菌存活。然而,目前尚不清楚这些系统如何保护免受致命的细菌。在这里,我们通过实验表明,黑脓果胶杆菌的I型CRISPR免疫导致两种不相关的毒性细菌ΦTE和ΦM1的快速抑制。然而,与细菌感染温带真菌的情况不同,这是一种流产感染样表型的结果,其中感染的细胞不能在感染中存活,而是变得代谢不活跃并失去其膜完整性。我们的研究结果挑战了CRISPR-Cas作为保护单个细胞的系统的观点,并支持越来越多的证据表明某些类型的CRISPR-Cas系统具有类似Abi的功能。
Type I CRISPR-Cas systems are the most abundant and widespread adaptive immune systems of bacteria and can greatly enhance bacterial survival in the face of temperate phage infection. However, it is less clear how these systems protect against virulent phages. Here we experimentally show that type I CRISPR immunity ofPectobacterium atrosepticumleads to rapid suppression of two unrelated virulent phages, ΦTE and ΦM1. However, unlike the case where bacteria are infected with temperate phages, this is the result of an abortive infection-like phenotype, where infected cells do not survive the infection but instead become metabolically inactive and lose their membrane integrity. Our findings challenge the view of CRISPR-Cas as a system that protects the individual cell and supports growing evidence of an Abi-like function for some types of CRISPR-Cas systems.
