Abstract:

Nuclease-mediated genome editing technologies contribute to the rapid advances in life sciences via the ability to edit the genomes within living cells, and present a new era for porcine genetic improvement. In this review, we introduce the development of various genomic editing technologies, particularly CRISPR/Cas9 strategies and characteristics of various naturally occurring and artificially engineered CRISPR enzymes. Also, we summarize progress in pig genetic improvement mediated by genome editing, especially those associated with meat quality traits and anti-virus resistance. We highlight the challenges in the implementation of pig genetic improvement and the prospects of pig genetic breeding based on genome editing technologies.

Key words: pig, genomic editing, genetic improvement
