Japanese quail (Coturnix japonica) is the highest-producing poultry species and a model species in developmental, behavioral, vertebrate physiology and disease studies. The size of its genome is ~1.41 Gb being 1/7 time bigger than the chicken’s one. According to the International Quail Genome Consortium estimation, the amount of repeat sequences in C. japonica genome is about 25% that is much higher than in other avian genomes. Repetitive elements compose an essential part of constitutive heterochromatin of the centromere regions as well as the p-arms of acrocentric macrochromosomes CJA3-5 and most of the microchromosomes. Therefore, accumulation of repetitive sequences and transposable elements probably led to quail genome increased size. Besides telomeric (TTAGGG)n repeat, only PO41 and BglII 41 bp tandem repeats were described in the Japanese quail genome to date. In this work, we performed a search of tandem repeats in unassembled short raw read datasets of the Japanese quail genome deep sequencing. We found 23 tandem repeats representing at least 4.8% of the Japanese quail genome. FISH with specific oligonucleotide probes revealed some of them contribute to heterochromatin of short arms of CJA3, CJA4 and microchromosomes. Repeat CjapSAT was found in pericentromeric heterochromatin on CJA 1-6 and three pairs of microchromosomes, as well as in p- and q-arms of CJAW. The description of satellite repeats is a necessary step to understand the significance of satellite DNA for the genome functioning and genome changes during the evolutionary process.
