Abstract

In the past two decades, with the discovery of RNA interference (RNAi) or post-transcriptional gene silencing (PTGS), the modern molecular biology field has been boosted with its immense applications. This rapid and powerful silencing method is useful in studying the gene function as well as in therapeutic applications for disease treatment. The RNAi or PTGS is a biological process of mRNA degradation induced by complementary double-stranded (ds) small interfering RNA (siRNA) sequences that mediate suppression of target protein-coding gene expression and provide resistance to both exogenous and endogenous microbial nucleic acids. This sequence-specific natural gene silencing mechanism has revolutionized experimental biology. RNAi technology has important practical applications in aquatic animal health, including functional genomics, therapeutic intervention, and other areas. Here in this chapter, we introduced the RNAi or PTGS mechanisms and the current understanding of gene silencing in aquatic animals in both fish and shellfish and will propose key areas of aquaculture fields where gene silencing could be applied.
