A microsatellite-based high-density genetic map facilitates for fine mapping of hereditary traits of interest, characterization of meiosis, and providing a foundation for physical map construction. Here, we developed a comprehensive genetic map on the basis of >880,000 genotypes across the USDA MARC cattle reference families with a potential genetic… (More)
To map quantitative trait loci (QTL) for growth and carcass traits in a purebred Japanese Black cattle population, we conducted multiple QTL analyses using 15 paternal half-sib families comprising 7860 offspring. We identified 40 QTL with significant linkages at false discovery rates of less than 0.1, which included 12 for intramuscular fat deposition… (More)
A bovine whole genome 7000-rad radiation hybrid (RH) panel, SUNbRH(7000-rad), was constructed to build a high-resolution RH map. The Shirakawa-USDA linkage map served as a scaffold to construct a framework map of 3216 microsatellites on which 2377 ESTs were ordered. The resulting RH map provided essentially complete coverage across the genome, with 1 cR7000… (More)
The MR and pathologic findings of a case of sclerosing stromal tumor (SST) are presented. MR findings reflecting pathological features of SST include pseudolobulation, which consists of low-intensity nodules set against high-intensity stroma on T2-weighted images, and striking enhancement on postcontrast images.
Chondrodysplastic dwarfism in Japanese brown cattle is an autosomal recessive disorder characterized by short limbs. Previously, we mapped the locus responsible for the disease on the distal end of bovine chromosome 6. Here, we narrowed the critical region to approximately 2 cM by using linkage analysis, constructed a BAC and YAC contig covering this… (More)
A vision-impairing ocular disorder was observed in a local Japanese Black cattle population, and assumed to be an autosomal recessive disease based on the presence of a founder cow. A genome scan using seven affected half-sib pairs revealed a linkage to BTA5 (Z(max) = 7.0, LOD(max) = 2.0), designated the bovine ocular disorder 1 (bod1) locus. Of the seven… (More)
We have constructed a bovine yeast artificial chromosome (YAC) library to provide a common resource for bovine genome research. We used leukocytes of a Japanese black bull (Bos taurus) as the DNA source, AB1380 for the yeast host, and pYAC4 for the vector. The library consists of 24,576 clones arranged in 256 96-well microtiter plates. An average insert… (More)
BACKGROUND Bovine chromosome (BTA) 15 contains a quantitative trait loci (QTL) for meat tenderness, as well as several breaks in synteny with human chromosome (HSA) 11. Both linkage and radiation hybrid (RH) maps of BTA 15 are available, but the linkage map lacks gene-specific markers needed to identify genes underlying the QTL, and the gene-rich RH map… (More)
Defective xanthine dehydrogenase (XDH) activity in humans results in xanthinuria and xanthine calculus accumulation in kidneys. Bovine xanthinuria was demonstrated in a local herd and characterized as xanthinuria type II, similar to the Drosophila ma-l mutations, which lose activities of molybdoenzymes, XDH, and aldehyde oxidase, although sulfite oxidase… (More)
A rare case of diaphragm hernia containing an accessory spleen and great omentum is reported. Tc-99m phytate SPECT showed tracer accumulation in the accessory spleen and was useful in the evaluation of the disease.
