To generate a domestic horse genome map we integrated synteny information for markers screened on a somatic cell hybrid (SCH) panel with published information for markers physically assigned to chromosomes. The mouse-horse SCH panel was established by fusing pSV2neo transformed primary horse fibroblasts to either RAG or LMTk mouse cells, followed by G418(More)
Thirty-six new horse microsatellites (11 from plasmid libraries and 25 from a cosmid library) were isolated and characterized on a panel of four horse breeds. Thirty were found to be polymorphic with heterozygosity levels ranging between 0.20 and 0.87. Twenty-two of the cosmids were physically mapped to R-banded single horse Chromosomes (Chrs) 1, 3, 4, 9,(More)
A horse BAC library was constructed with about 40, 000 clones and mean insert size of 110 kb representing a 1.5 genome equivalent coverage and a probability of finding a single sequence of 0.75. It was characterized by PCR screening of about 130 sequences of horse microsatellites and exonic gene sequences retrieved from databases. BACs containing 8(More)
The goal of the First International Equine Gene Mapping Workshop, held in 1995, was the construction of a low density, male linkage map for the horse. For this purpose, the International Horse Reference Family Panel (IHRFP) was established, consisting of 12 paternal half-sib families with 448 half-sib offspring provided by 10 laboratories. Blood samples(More)
The melanocortin 1 receptor (MC1R), mast/stem cell growth factor receptor (KIT), and platelet-derived growth factor receptor α (PDGFRA) are loci that all belong to equine linkage group 2 (LG2). Of these, KIT was fluorescent in situ hybridization (FISH) mapped to ECA3q21 with equine cDNA and heterologous porcine BAC probes, while MC1R was localized to(More)
We report fluorescence in-situ hybridization (FISH) and somatic cell hybrid mapping data for 13 different horse genes (ANP, CD2, CLU, CRISP3, CYP17, FGG, IL1RN, IL10, MMP13, PRM1, PTGS2, TNFA and TP53). Primers for PCR amplification of intronic or untranslated regions were designed from horse-specific DNA or mRNA sequences in GenBank. Two different horse(More)
The purpose of this study was to generate repetitive DNA sequence probes for the analysis of interphase nuclei by fluorescent in situ hybridisation (FISH). Such probes are useful for the diagnosis of chromosomal abnormalities in bovine preimplanted embryos. Of the seven probes (E1A, E4A, Ba, H1A, W18, W22, W5) that were generated and partially sequenced,(More)
The purpose of this study was to increase the number of genes assigned by in situ hybridization to equine chromosomes and thus the number of links for comparative mapping with other species. Forty-four new sequences were added to the horse cytogenetic map by FISH mapping of BAC clones containing genes (35) or ESTs (9). Three approaches were developed: use(More)
