Locus number estimation of MHC class II B in stone flounder and Japanese flounder.

ABSTRACT: Members of major histocompatibility complex (MHC) family are important in immune systems. Great efforts have been made to reveal their complicated gene structures. But many existing studies focus on partial sequences of MHC genes. In this study, by gene cloning and sequencing, we identified cDNA sequences and DNA sequences of the MHC class II B in two flatfishes, stone flounder (Kareius bicoloratus) and homozygous diploid Japanese flounder (Paralichthys olivaceus). Eleven cDNA sequences were acquired from eight stone flounder individuals, and most of the polymorphic sites distributed in exons 2 and 3. Twenty-eight alleles were identified from the DNA fragments in these eight individuals. It could be deduced from their Bayesian inference phylogenetic tree that at least four loci of MHC clas
