The Escherichia coli F18 receptor locus (ECF18R) has been genetically mapped to the halothane linkage group on porcine Chromosome (Chr) 6. In an attempt to obtain candidate genes for this locus, we isolated 5 cosmids containing the α(1,2)fucosyltransferase genes FUT1, FUT2, and the pseudogene FUT2P from a porcine genomic library. Mapping by fluorescence in(More)
Gene mapping in cattle has progressed rapidly in recent years largely owing to the introduction of powerful genetic markers, such as the microsatellites, and through advances in physical mapping techniques such as synteny mapping and fluorescence in situ hybridization (FISH). Microsatellite markers are often not physically mapped because they are generally(More)
As a new approach to parentage control we developed two multiplex coamplification polymerase chain reaction (PCR) systems containing a total of six different short tandem repeat (STR) loci; the microsatellite polymorphisms were visualized by automated fluorescence detection on the Applied Biosystems 373 DNA Sequencer with 672 Genescan Analysis software.(More)
Upon substituting Ca for Eu in the local-moment ferromagnet EuB6, the Curie temperature T(C) decreases substantially with increasing dilution of the magnetic sublattice and is completely suppressed for x<or=0.3. The Ca substitution leads to significant changes of the electronic properties across the EuxCa1-xB6 series. Electron microscopy data for x(More)
Genetically directed representational difference analysis (GDRDA) allows to isolate DNA fragments that differ between complex genomes. This approach was applied in the present work to isolate Y-specific bovine sequences. Of eight isolated and cloned fragments, two proved to be Y-specific.
Species: Mouse Locus name: methionine synthase or 5-methyltetrahydrofolatehomocysteine methyltransferase Locus symbol: Mtr Map position: proximal–D13Mit1–1.06 cM ± 1.06 SE–Mtr, D13Bir4, D13Bir6–1.06 ± 1.06–D13Abb1e–2.13 ± 1.49–D13Bir7–distal Method of mapping: Mtr was localized by RFLP analysis of 96 animals from an interspecific backcross panel(More)
