Microsatellite evolution--a reciprocal study of repeat lengths at homologous loci in cattle and sheep.

Survey of Efficiency of Six Microsatellite Loci in Iranian Indigenous Cattle and Buffalo Populations

Microsatellite length differences between humans and chimpanzees at autosomal Loci are not found at equivalent haploid Y chromosomal Loci.

When homologous microsatellites are compared between species, significant differences in mean length are often noted. A dominant cause of these length differences is ascertainment bias due to selection for maximum repeat number and repeat purity when the markers are being developed. However, even after ascertainment bias has been allowed for through reciprocal comparisons, significant length di...

Microsatellite Isolation and Characterization in Pomegranate (Punica granatum L.)

Development of microsatellite markers has been an increasing trend in crop genetic studies because oftheir applicability in breeding programs. Here we report the development of inter simple sequencerepeat (SSRs) in pomegranate (Punica granatum L.) using an enrichment method that makes use of magneticbeads. Enriched genomic libraries with AG and ATG microsatellite motifs were c...

Extensive genomic conservation of cattle microsatellite heterozygosity in sheep.

We report the evaluation of 1036 bovine microsatellite primer pairs for their suitability as linkage markers in sheep. Approximately 58% (605/1036) of bovine primer pairs amplified a locus in sheep. Sixty-seven per cent (409/605) of amplified loci were detected as polymorphic. Marker heterozygosity, allele number and range of allele sizes were significantly lower in sheep than cattle sampled in...

An advanced sheep (Ovis aries, 2n = 54) cytogenetic map and assignment of 88 new autosomal loci by fluorescence in situ hybridization and R-banding

Presented herein is an updated sheep cytogenetic map that contains 452 loci (291 type I and 161 type II) assigned to specific chromosome bands or regions on standard R-banded ideograms. This map, which significantly extends our knowledge of the physical organization of the ovine genome, includes new assignments for 88 autosomal loci, including 74 type I loci (known genes) and 14 type II loci (S...
