Shared Y chromosome repetitive DNA sequences in stallion and donkey as visualized using whole-genomic comparative hybridization
نویسندگان
چکیده
The genome of stallion (Spanish breed) and donkey (Spanish endemic Zamorano-Leonés) were compared using whole comparative genomic in situ hybridization (W-CGH) technique, with special reference to the variability observed in the Y chromosome. Results show that these diverging genomes still share some highly repetitive DNA families localized in pericentromeric regions and, in the particular case of the Y chromosome, a sub-family of highly repeated DNA sequences, greatly expanded in the donkey genome, accounts for a large part of the chromatin in the stallion Y chromosome.

Chromosomal defects are relatively frequent in infertile men however, translocations between the Y chromosome and autosomes are rare and less than 40 cases of Y-autosome translocation have been reported. In particular, only three individuals has been described with a Y;21 translocation, up to now. We report on an additional case of an infertile man in whom a Y;21 translocation was associated wi...

The main objective of the present study was to develop an efficient and reliable probe to be routinely used for detection of chromosome 13 copy numbers by interphase FISH. To achieve this, a Yeast Artificial Chromosome (YAC) containing sequences specific for human 13q12 (744D11), was cultured and the whole yeast genomic DNA was extracted. The human insert within the isolated DNA was amplified b...
متن کاملConstitutive heterochromatin polymorphisms in human chromosomes identified by whole comparative genomic hybridization
Whole comparative genomic hybridization (W-CGH) is a new technique that reveals cryptic differences in highly repetitive DNA sequences, when different genomes are compared using metaphase or interphase chromosomes. W-CGH provides a quick approach to identify differential expansion of these DNA sequences at the single-chromosome level in the whole genome. In this study, we have determined the fr...

Repetitive DNAs have been extensively applied as physical chromosome markers on comparative studies, identification of chromosome rearrangements and sex chromosomes, chromosome evolution analysis, and applied genetics. Here we report the characterization of repetitive DNA sequences from the Nile tilapia (Oreochromis niloticus) genome by construction and screening of plasmid library enriched wit...
متن کاملSequence-based design of single-copy genomic DNA probes for fluorescence in situ hybridization.
Chromosomal rearrangements are frequently monitored by fluorescence in situ hybridization (FISH) using large, recombinant DNA probes consisting of contiguous genomic intervals that are often distant from disease loci. We developed smaller, targeted, single-copy probes directly from the human genome sequence. These single-copy FISH (scFISH) probes were designed by computational sequence analysis...
