Background: Haliotis discus hannai more commonly referred to as the Pacific Abalone is of significant commercial and economical value in South Korea, with it being the second largest producer in the world. Despite this significance there is a lack of genetic studies with regards to the species. Most existing studies focused mainly on environmental factors.
Objective: To provide a comprehensive review describing the genetic feature of Haliotis discus hannai by infection of vibrio and virus.
Methods: This review summarized the immune response in the Haliotis spp. with regards to immunological genes such as Cathepsin B, C-type lectin and Toll-like receptors. Genetic studies with regards to transposable elements and miRNAs are few and far between. A study identified LTR retrotransposon Ty3/gypsy in the species. As to miRNA, a single study identified numerous miRNAs in the Haliotis discus hannai.
Conclusion: This paper sought to provide an overview of genetic perspective with regards to immune response genes, transposable elements and miRNAs.
Keywords: Haliotis discus hannai; Immune genes; Transposable element; miRNA.
