초록

To successful molecular breeding, identification and functional characterization of breeding related genes anddevelopment of molecular breeding techniques using DNA markers are essential. Although the development of a usefulmarker is difficult in the aspect of time, cost and effort, many markers are being developed to be used in molecular breedingand developed markers have been used in many fields. Single nucleotide polymorphisms (SNPs) markers were widely usedfor genomic research and breeding, but has hardly been validated for screening functional genes in olive flounder. Weidentified single nucleotide polymorphisms (SNPs) from expressed sequence tag (EST) database in olive flounder; out of atotal 4,327 ESTs, 693 contigs and 514 SNPs were detected in total EST, and these substitutions include 297 transitions and217 transversions. As a result, 144 SNP markers were developed on the basis of 514 SNP to selection of useful gene region,and then applied to each of eight wild and culture olive flounder (total 16 samples). In our experimental result, only 32markers had detected polymorphism in sample, also identified 21 transitions and 11 transversions, whereas indel was notdetected in polymorphic SNPs. Heterozygosity of wild and cultured olive flounder using the 32 SNP markers is 0.34 and 0.29,respectively. In conclusion, we identified SNP and polymorphism in olive flounder using newly designed marker, it supportsthat developed markers are suitable for SNP detection and diversity analysis in olive flounder. The outcome of this study canbe basic data for researches for immunity gene and characteristic with SNP.

Abstract

To successful molecular breeding, identification and functional characterization of breeding related genes anddevelopment of molecular breeding techniques using DNA markers are essential. Although the development of a usefulmarker is difficult in the aspect of time, cost and effort, many markers are being developed to be used in molecular breedingand developed markers have been used in many fields. Single nucleotide polymorphisms (SNPs) markers were widely usedfor genomic research and breeding, but has hardly been validated for screening functional genes in olive flounder. Weidentified single nucleotide polymorphisms (SNPs) from expressed sequence tag (EST) database in olive flounder; out of atotal 4,327 ESTs, 693 contigs and 514 SNPs were detected in total EST, and these substitutions include 297 transitions and217 transversions. As a result, 144 SNP markers were developed on the basis of 514 SNP to selection of useful gene region,and then applied to each of eight wild and culture olive flounder (total 16 samples). In our experimental result, only 32markers had detected polymorphism in sample, also identified 21 transitions and 11 transversions, whereas indel was notdetected in polymorphic SNPs. Heterozygosity of wild and cultured olive flounder using the 32 SNP markers is 0.34 and 0.29,respectively. In conclusion, we identified SNP and polymorphism in olive flounder using newly designed marker, it supportsthat developed markers are suitable for SNP detection and diversity analysis in olive flounder. The outcome of this study canbe basic data for researches for immunity gene and characteristic with SNP.
