CRISPR systems canonically confer microorganisms with protection against invading viral DNA, plasmids and mobile genetic elements, however a multi-omics investigation of deep subsurface archaeal communities suggests that archaeal CRISPR systems might target other archaeal parasites or force a transition from parasitism to mutualism.
CRISPR 系统通常使微生物免受入侵的病毒 DNA、质粒和可移动遗传元件的侵害，但对深层地下古菌群落的多组学研究表明，古菌 CRISPR 系统可能针对其他古菌寄生虫，或迫使从寄生关系转变为共生关系。
