A new ALF from Litopenaeus vannamei and its SNPs related to WSSV resistance

Anti-lipopolysaccharide factors (ALFs) are basic components of the crustacean immune system that defend against a range of pathogens. The cDNA sequence of a new ALF, designated nLvALF2, with an open reading frame encoding 132 amino acids was cloned. Its deduced amino acid sequence contained the cons...

description Anti-lipopolysaccharide factors (ALFs) are basic components of the crustacean immune system that defend against a range of pathogens. The cDNA sequence of a new ALF, designated nLvALF2, with an open reading frame encoding 132 amino acids was cloned. Its deduced amino acid sequence contained the conserved functional domain of ALFs, the LPS binding domain (LBD). Its genomic sequence consisted of three exons and four introns. nLvALF2 was mainly expressed in the Oka organ and gills of shrimps. The transcriptional level of nLvALF2 increased significantly after white spot syndrome virus (WSSV) infection, suggesting its important roles in protecting shrimps from WSSV. Single nucleotide polymorphisms (SNPs) were found in the genomic sequence of nLvALF2, of which 38 were analyzed for associations with the susceptibility/resistance of shrimps to WSSV. The loci g.2422 A>G, g.2466 T>C, and g.2529 G>A were significantly associated with the resistance to WSSV (P
