细菌和古生菌拥有许多防御系统来对抗病毒感染和其他移动的遗传元素。其中独特的是,CRISPR-Cas(成簇的、规则间隔的短回文重复序列-CRISPR相关)提供了针对外源核酸的适应性遗传干扰。本文综述了奈瑟氏菌CRISPR-Cas9系统的最新研究进展,重点介绍了其在遗传转移中的生物学功能、建立新范式的机制特征及其在真核基因组工程中的技术应用。
Bacteria and archaea possess numerous defense systems to combat viral infections and other mobile genetic elements. Uniquely among these, CRISPR-Cas (clustered,regularlyinterspacedshortpalindromicrepeats-CRISPR associated) provides adaptive genetic interference against foreign nucleic acids. Here we review recent advances on the CRISPR-Cas9 system inNeisseriaspp, with a focus on its biological functions in genetic transfer, its mechanistic features that establish new paradigms and its technological applications in eukaryotic genome engineering.
