Amplification of an ancestral lysozyme gene in artiodactyls is associated with the evolution of foregut fermetation in the ruminant lineage and has resulted in about ten lysozyme genes in true ruminants. Hybridization of a cow stomach lysozyme 2 cDNA clone to restricted DNAs of a panel of cowxhamster hybrid cell lines revealed that all but one of the multiple bovine-specific bands segregate concordantly with the marker for bovine syntenic group U3 [Chromosome (Chr) 5]. The anomalous band was subsequently mapped to bovine syntenic group U22 (Chr 7) with a second panel of hybrids representing all 31 bovine syntenic groups. By two-dimensional pulsed-field gel electrophoresis the lysozyme genes on cattle Chr 5 were shown to be clustered on a 2- to 3-Mb DNA fragment, while the lactalbumin gene and pseudogenes that are paralogous and syntenic with the lysozymes were outside the lysozyme gene cluster. Chromosomal fluorescence in situ hybridization of a cocktail of lysozyme genomic clones localized the lysozyme gene cluster to cattle Chr 5 band 23, corroborating the somatic cell assignment. 相似文献

Comparative fine maps of bovine toll-like receptor 4 and toll-like receptor 2 regions 总被引:5,自引:0,他引:5
Abstract
Toll-like receptors are cell-surface receptors that activate innate and adaptive immune responses. We have used a 5000-rad,
whole-genome radiation hybrid panel to map Toll-like receptor 4 (TLR4) to the distal end of bovine Chromosome (Chr) 8, and
Toll-like receptor 2 (TLR2) to the proximal end of bovine Chr 17. To facilitate comparative mapping and contig construction,
we have also used 5000- and 12,000-rad, whole-genome radiation hybrid panels to produce fine maps of the regions surrounding
these genes in cattle. These fine maps triple the number of available markers in the TLR4 region and more than double the
number of available markers in the TLR2 region. Comparative analyses show gene order conservation between the bovine Chr 8
region and human Chr 9, and between the bovine Chr 17 region and human Chr 4. In addition, the bovine Chr 8 region refines
an evolutionary chromosomal breakpoint from a 10-megabase region to a 2.5-megabase region, and the bovine Chr 17 map suggests
a new evolutionary chromosomal breakpoint. 相似文献

A second-generation linkage map of the sheep genome 总被引:32,自引:0,他引:32

A genetic map of Ovis aries (haploid n = 27) was developed with 519 markers (504 microsatellites) spanning ∼3063 cM in 26 autosomal linkage groups and
127 cM (female specific) of the X Chromosome (Chr). Genotypic data were merged from the IMF flock (Crawford et al., Genetics
140, 703, 1995) and the USDA mapping flock. Seventy-three percent (370/504) of the microsatellite markers on the map are common
to the USDA-ARS MARC cattle linkage map, with 27 of the common markers derived from sheep. The number of common markers per
homologous linkage group ranges from 5 to 22 and spans a total of 2866 cM (sex average) in sheep and 2817 cM in cattle. Marker
order within a linkage group was consistent between the two species with limited exceptions. The reported translocation between
the telomeric end of bovine Chr 9 (BTA 9) and BTA 14 to form ovine Chr 9 is represented by a 15-cM region containing 5 common
markers. The significant genomic conservation of marker order will allow use of linkage maps in both species to facilitate
the search for quantitative trait loci (QTLs) in cattle and sheep.

Two major differences were detected in gene order between the radiation hybrid map and the genetic linkage map of bovine
Chromosome (Chr) 5, and these were resolved by analyzing the raw radiation hybrid data by a quasi-phylogenetic method. Seventeen
loci were typed on the new cattle whole genome radiation hybrid panel. Most of these loci are framework loci and include AGLA293, BM315, BM6026, BP1, BZRP, CD9, CSSM22, CSSM34, CYP2D@, ETH2, ETH10, ETH152, IGF1, LALBA, SLC2A3, SYT1, and TPI1. BP1 was found to be closer to the centromere than either BM6026 or SYT1 with two standard computer software packages for analyzing radiation hybrid panel data. This is inconsistent with any of
the genetic linkage maps as well as their consensus. CYP2D@ was placed between ETH2 and BZRP, and this is also inconsistent with the genetic linkage maps, since CYP2D@ should be the most telomeric of the loci tested in this study. Resolution was reached by analyzing the raw radiation hybrid
data for clones that bind some but not all of the loci, and the binding pattern was more consistent with the linkage maps
and less consistent with the software-generated radiation hybrid map. The comparative mapping data confirm the relative inversion
of gene order of SYT1 compared with humans and mice. A non-polymorphic fragment for CD9 indicates the conservation of gene order for three loci
located on human Chr 12p. The genes of bovine Chr 5 conserved on human Chr 12p are located separately from the genes conserved
on human Chr 12q. It is recommended that the raw data for radiation hybrid maps be made publicly available so that conflicts
in gene order can be evaluated explicity.

The cosmid-derived microsatellite CSSM 25 has previously been shown to map to bovine syntenic group U2 by link-age and hybrid somatic cell analysis. We have mapped the cosmid by fluorescent in situ hybridization to bovine Chromosome (Chr) 9q17-21 and ovine Chr 8q17-21 and hence assign U2 to Chr 9 in cattle. Bovine Chr 9 and ovine Chr 8 show strong banding pattern homology, and the localization of CSSM 25 to the same region confirms the strong conservation of gene locations on these chromosomes. 相似文献

The linkage map of sheep Chromosome 6 compared with orthologous regions in other species 总被引:9,自引:0,他引:9
E. A. Lord J. M. Lumsden K. G. Dodds H. M. Henry A. M. Crawford H. A. Ansari P. D. Pearce D. W. Maher R. T. Stone S. M. Kappes C. W. Beattie G. W. Montgomery 《Mammalian genome》1996,7(5):373-376
The genetic linkage map of sheep Chromosome (Chr) 6 has been extended to include 35 loci with the addition of 11 RFLP and
12 microsatellite loci. The sex-averaged linkage map now spans 154 cM from phosphodiesterase cyclic GMP beta polypeptide (PDE6B) to OarCP125, an anonymous sheep microsatellite. The male and female map lengths, at 180 cM and 132 cM respectively, did not differ significantly.
The physical assignment of PDE6B to Chr 6q33-qter orientates the linkage map on sheep Chr 6 with PDE6B near the telomere and OarCP125 towards the centromere. The order and genetic distances between loci are similar for the sheep Chr 6 and cattle Chr 6 maps,
except for the position of the casein genes. The sheep Chr 6 linkage map is also comparable to portions of human Chr 4, mouse
Chrs 5 and 3, and pig Chr 8. The synteny between sheep Chr 6 and human Chr 4 has been extended from PDE6B (4p16.3) to epidermal growth factor (EGF, 4q25-q27). However, a region from platelet-derived growth factor receptor α polypeptide (PDGFRA) to bone morphogenetic protein 3 (BMP3), which spans 19 cM on sheep Chr 6, appears to be inverted with respect to the human and mouse loci. Other differences in
the gene order between sheep, pig, and mouse suggest more complex rearrangements.

Porcine linkage and cytogenetic maps integrated by regional mapping of 100 microsatellites on somatic cell hybrid panel 总被引:1,自引:1,他引:0

Recently two main genetic maps [Rohrer et al. Genetics 136, 231 (1994); Archibald et al. Mamm. Genome 6, 157 (1995)] and
a cytogenetic map [Yerle et al. Mamm. Genome 6, 175 (1995)] for the porcine genome were reported. As only a very few microsatellites
are located on the cytogenetic map, it appears to be important to increase the relationships between the genetic and cytogenetic
maps. This document describes the regional mapping of 100 genetic markers with a somatic cell hybrid panel. Among the markers,
91 correspond to new localizations. Our study enabled the localization of 14 new markers found on both maps, of 54 found on
the USDA map, and of 23 found on the PiGMaP map. Now 21% and 43% of the markers on the USDA and PiGMaP linkage maps respectively
are physically mapped. This new cytogenetic information was then integrated within the framework of each genetic map. The
cytogenetic orientation of the USDA linkage maps for Chromosomes (Chrs) 3, 8, 9, and 16 and of PiGMaP for Chr 8 was determined.
USDA and PiGMaP linkage maps are now oriented for all chromosomes, except for Chrs 17 and 18. Moreover, the linkage group
``R' from the USDA linkage map was assigned to Chr 6.

Screening a bovine Y Chromosome-specific DNA library resulted in 34 new microsatellites, six of which mapped to the pseudoautosomal
region (PAR), and 28 localized to the Y-specific region. These microsatellites, together with 23 markers previously mapped
to the bovine Y Chr, were scored on a 7000-rad cattle–hamster radiation hybrid (RH) panel. Retention frequency of individual
markers ranged from 18.5% to 76.5% with an average of 48.4%. Markers with high retention frequency (>55%) were found to exist
in multiple copies on the Y Chr. Thirteen markers were placed on the PAR RH map with the AmelY gene proximal to the pseudoautosomal boundary and 46 markers, including Sry and Tspy gene, on the Y-specific region of the RH map. The microsatellites developed and mapped in this work will be useful for comparative
mapping of cattle, sheep, and goat, studying the origin, evolution, and migration of bovidae species and provide an initial platform to develop a high-resolution map of the Y Chr and positional cloning of Y-specific
genes. 相似文献

In the Belgian Blue Cattle breed, coat color variation is mainly under the influence of a single autosomal locus, the roan
locus, characterized by a pair of codominant alleles: r
+ (black) and R (white). Heterozygous r
+
R animals have intermingled black and white hairs, yielding the ``blue' phenotype typical of the breed. Major interest for
the roan locus stems from its pleiotropic effect on fertility, owing to the critical role of the R allele in the determinism
of White Heifer Disease. We describe the linkage mapping of the roan locus to bovine Chromosome (Chr) 5, in the interval between
microsatellite markers BPI and AGLA293, with an associated lodscore of 11.2. Moreover, we map a candidate gene, the Steel locus coding for the mast cell growth factor,
to bovine Chr 5.

A hereditary chondrodysplastic dwarfism caused by an autosomal recessive gene has been reported in a population of Japanese
Brown cattle. Affected calves show an insufficiency of endochondral ossification at the long bones of the limbs. In the present
study, we mapped the locus responsible for the disease (bcd) by linkage analysis, using microsatellite markers and a single paternal half-sib pedigree obtained from commercial herds.
Linkage analysis revealed a significant linkage between the bcd locus and marker loci on the distal region of bovine Chromosome (Chr) 6. The bcd locus was mapped in the interval between microsatellite markers BM9257 and BP7 or BMS511 with a recombination fraction of 0.05 and 0.06, and a lod score of 8.6 and 10.1, respectively. A comparison of genetic maps
between bovine Chr 6 and human Chr 4 or mouse Chr 5 indicates possible candidate genes including FGFR3 and BMP3 genes, which
are responsible for human chondrodysplasias and associated with bone morphogenesis, respectively.

Renal tubular dysplasia is a hereditary disease of Japanese black cattle showing renal failure and growth retardation with
an autosomal recessive trait. In the present study, we mapped the locus responsible for the disease (RTD) by linkage analysis with an inbred paternal half-sib pedigree obtained from commercial herds. By analyzing segregation of
microsatellite markers in the half-sibs, significant linkage was observed between the RTD locus and markers on bovine Chromosome (Chr) 1 with the highest lod score of 11.4. Homozygosity mapping with the inbred pedigree
further defined the localization of the RTD locus in a 4-cM region between microsatellite markers BMS4003 and INRA119. Mapping of the RTD locus on bovine Chr 1 will facilitate cloning and characterization of the gene responsible for this disease.

Localization of the locus responsible for Chediak-Higashi syndrome in cattle to bovine chromosome 28
Chediak-Higashi syndrome in Japanese black cattle is a hereditary disease with prolonged bleeding time and partial albinism. In the present study, we mapped the locus responsible for the disease (CHS) by linkage analysis using microsatellite genotypes of paternal half-sib pedigrees obtained from commercial herds. Analysis revealed significant linkage between the CHS locus and marker loci on the proximal end of bovine chromosome 28. The CHS locus was mapped on the region incorporating the microsatellite markers BMC6020, BM2892, and RM016 with recombination fraction 0 and lod score 4.9-11.2. We also assigned the bovine CHS1/LYST, the homologue of the gene responsible for human Chediak-Higashi syndrome, to bovine chromosome 28 using a bovine/murine somatic cell hybrid panel. These findings suggest that a mutation in the CHS1/LYST gene is likely to be responsible for Chediak-Higashi syndrome in Japanese black cattle. 相似文献

The nucleophosmin (nucleolar phosphoprotein B23, numatrin) gene (NPM1, previously known as nucleophosmin/nucleoplasmin family, member 1) encodes a multifunctional nucleolar phosphoprotein that plays a crucial role in cell growth and homeostasis. Seven sequence variants (SVs) were identified in the coding region of bovine NPM1, five of which were in complete linkage disequilibrium. Eight different haplotypes were identified, of which two major haplotypes have a frequency of 23.2% and 20.4%. Three SVs were significantly associated with body weight in the Nanyang population as analysed at different ages. No significant association was detected between 18 combined genotypes and body weight at five different ages. Our results suggest that some polymorphisms in NPM1 are associated with body weight at some ages and may be used as candidates for marker-assisted selection and management in beef cattle breeding programmes. 相似文献

We present a comprehensive radiation hybrid map of the bovine X chromosome (Chr) containing 20 new markers, including both
microsatellites and expressed genes. This study was conducted with a 5000-rad whole genome RH cell panel consisting of 90
hybrid cell lines. Retention frequencies of individual markers range from 7.8% for XIST to 31.1% for TGLA325. Statistical
analysis with RHMAPPER placed all the loci into five linkage groups under a LOD score criterion of 6.0. These groups could
be oriented relative to each other because they included multiple microsatellite loci from the consensus linkage map of the
X Chr. Markers included in both this RH map and the bovine cytogenetic map were in a consistent order. The comparative bovine–human
map thus generated consists of five blocks of genes, the order of which is conserved, although in the opposite direction when
presented as ideograms with p and q arms. Inversions of three blocks account for the difference in gene order across the entirety
of the two X Chrs. 相似文献

Five overlapping lambda EMBL-clones, containing the complete bovine lactoferrin gene (LTF), have been used to map this gene by fluorescence in situ hybridization to bovine Chromosome (Chr) band 22q24. Primers derived from promoter and exon I sequences were applied in polymerase chain reactions (PCRs) to DNA samples of a previously characterized panel of somatic cell hybrid lines, allowing the assignment of the bovine lactoferrin locus to syntenic group U12. These results permit the assignment of syntenic group U12 to bovine Chr 22. 相似文献

The largest chromosome in the river buffalo karyotype, BBU1, is a submetacentric chromosome with reported homology between BBU1q and bovine chromosome 1 and between BBU1p and BTA27. We present the first radiation hybrid map of this chromosome containing 69 cattle derived markers including 48 coding genes, 17 microsatellites and four ESTs distributed in two linkage groups spanning a total length of 1330.1 cR(5000). The RH map was constructed based on analysis of a recently developed river buffalo-hamster whole genome radiation hybrid (BBURH(5000)) panel. The retention frequency of individual markers across the panel ranged from 17.8 to 52.2%. With few exceptions, the order of markers within linkage groups is identical to the order established for corresponding cattle RH maps. The BBU1 map provides a starting point for comparison of gene order rearrangements between river buffalo chromosome 1 and its bovine homologs. 相似文献

Polymorphism within the 3' flanking region of the bovine growth hormone receptor gene 总被引:2,自引:0,他引:2
Growth hormone receptor (GHR) has a major role in the regulation of growth hormone action, and thus, is an obvious candidate gene associated with milk production traits in mammals. The present authors have sequenced 273 bp of the 3' flanking region of the bovine GHR , and found three length variants and one base substitution polymorphism in this region. Allele frequencies of the length variants differ between Finnish native and commercial dairy cattle breeds. The chromosomal localization of GHR was confirmed to bovine chromosome 20 by synteny mapping and linkage analysis. 相似文献

A set of 99 cattle microsatellites: characterization,synteny mapping,and polymorphism 总被引:26,自引:0,他引:26

Cattle microsatellite clones (136) were isolated from cosmid (10) and plasmid (126) libraries and sequenced. The dinucleotide repeats were studied in each of these sequences and compared with dinucleotide repeats found in other vertebrate species where information was available. The distribution in cattle was similar to that described for other mammals, such as rat, mouse, pig, or human. A major difference resides in the number of sequences present in the bovine genome, which seemed at best one-third as large as in other species. Oligonucleotide primers (117 pairs) were synthesized, and a PCR product of expected size was obtained for 88 microsatellite sequences (75%). Synteny or chromosome assignment was searched for each locus with PCR amplification on a panel of 36 hamster/bovine somatic cell hybrids. Of our bovine microsatellites, eighty-six could be assigned to synteny groups of chromosomes. In addition, 10 other microsatellites—HEL 5, 6, 9, 11, 12, 13 (Kaukinen and Varvio 1993), HEL 4, 7, 14, 15—as well as the microsatellite found in the -casein gene (Fries et al. 1990) were mapped on the hybrids. Microsatellite polymorphism was checked on at leat 30 unrelated animals of different breeds. Almost all the autosomal and X Chr microsatellites displayed polymorphism, with the number of alleles varying between two and 44. We assume that these microsatellites could be very helpful in the construction of a primary public linkage map of the bovine genome, with an aim of finding markers for Economic Trait Loci (ETL) in cattle. 相似文献

Twenty-four microsatellite sites with at least three repeats were found in the bovine prion protein gene (PRNP) and 23 in the ovine PRNP gene. Eight microsatellite sites were polymorphic in cattle and six in sheep with up to 10 alleles per site. In many cases allelic DNA fragments had variants in microsatellite sites and in flanking regions. Distances between microsatellite sites in eight genes from cattle and sheep occurred on average every 0.9 kb. The numerous polymorphic microsatellite sites will improve analysis of phylogenetic origin of different PRNP alleles and trait association studies for bovine spongiform encephalopathy (BSE) and scrapie. 相似文献
