| Abstract: | Antimicrobial peptides directly play the immunity functions in the innate immunity system of the invertebrate.They play an important role in defending against the bacteria infection.In this paper,the Litopenaeus vannamei penaeidin 2 antibacterial peptides gene is the research object.And the gene cloning,amino acids sequences alignment,phylogenetic relationship analysis,and preliminary forecast for the molecular structure are mainly done.The results show that the Lva-pen 2 gene is an immunity response relevant gene.And it plays an important role in the innate immunity system of the Litopenaeus vannamei. |
