CRISPR/Cas9 technology and its progress in gene function research of aquatic organism.

Abstract

Cas9/sgRNA(single-guide RNA), a simplified derivative of CRISPR/Cas system, is gradually replacing zinc-finger nucleases(ZFNs) and transcription activator like effector nucleases(TALENs) due to its simple design, low cost and good repeatability, and is widely used in genome editing. After the modification of CRISPR/Cas system, it can be applied to high-throughput screening technology. Meanwhile, with the completion of whole-genome sequencing of numerous aquatic organisms and the rapid development of whole-genome screening technology, the research process of gene function of aquatic organisms will be greatly promoted. In this paper, the development of CRISPR/cas9 gene editing technology is introduced from the aspects of research history, system structure and simplification, and the application progress of CRISPR/cas9 gene editing technology in zebrafish and other aquatic organisms is reviewed in detail.
