Endogenous retroviruses (ERVs), eukaryotic transposable elements, exist as proviruses in vertebrates including primates and contribute to genomic changes during the evolution of their host genomes. Many studies about ERVs have focused on the elements residing in the human genome but only a few studies have focused on the elements which exist in non-human(More)
Chicken is one of the most popular domesticated species worldwide, as it can serve an important role in agricultural as well as biomedical research fields. Because it inhabits almost every continent and presents diverse morphology and traits, the need of genetic markers for distinguishing each breed for various purposes has increased. The whole genome(More)
Alu elements are the most successful short interspersed elements in primate genomes and their retrotransposition is a major source of genomic expansion. Alu elements integrate into genomic regions through target-site primed reverse transcription, which generates target site duplications (TSDs). Unexpectedly, we have identified target site triplications(More)
Mobile elements are responsible for ~45% of the human genome. Among them is the Alu element, accounting for 10% of the human genome (>1.1million copies). Several studies of Alu elements have reported that they are frequently involved in human genetic diseases and genomic rearrangements. In this study, we investigated the AluS subfamily, which is a(More)
Sequence analysis of the 16S rRNA gene has been widely used for the classification of microorganisms. However, we have been unable to clearly identify five Flavobacterium species isolated from a freshwater by using the gene as a single marker, because the evolutionary history is incomplete and the pace of DNA substitutions is relatively rapid in the(More)
Transposable elements (TEs) comprise ~10% of the chicken (Gallus gallus) genome. The content of TEs is much lower than that of mammalian genomes, where TEs comprise around half of the genome. Endogenous retroviruses are responsible for ~1.3% of the chicken genome. Among them is Gallus gallus endogenous retrovirus 10 (GGERV10), one of the youngest endogenous(More)
The manila clam, Ruditapes philippinarum, is an important bivalve species in worldwide aquaculture including Korea. The aquaculture production of R. philippinarum is under threat from diverse environmental factors including viruses, microorganisms, parasites, and water conditions with subsequently declining production. In spite of its importance as a marine(More)
The peroxisome proliferator-activated receptor gamma (PPARγ) gene plays an important role in the biosynthesis process controlled by a number of fatty acid transcription factors. This study investigates the relationships between 130 single-nucleotide polymorphisms (SNPs) in the PPARγ gene and the fatty acid composition of muscle fat in the commercial(More)
Approximately 80 long interspersed element (LINE-1 or L1) copies are able to retrotranspose actively in the human genome, and these are termed retrotransposition-competent L1s. The 5' untranslated region (UTR) of the human-specific L1 contains an internal promoter and several transcription factor binding sites. To better understand the effect of the L1 5'(More)
The human genome has various genomic structural variations such as insertion/deletions between human individuals. These structural variations have led to genomic fluidity and rearrangements in individuals and populations. To investigate Korean-specific structural genomic variations, we performed next generation sequencing with 30× mean coverage from 27(More)
