Mitochondrial Diversity and Phylogenetic Relationship of Eight Native Bulgarian Sheep Breeds.

The geographical, geomorphological, and climatic characteristics of Bulgaria are particularly favorable for animal breeding and, above all, for pastoral farming and sheep breeding. These conditions created prerequisites for the creation of about 30 unique local breeds of sheep. In this study we investigated the genetic diversity of eight of the most popular Bulgarian native breeds, based on the sequence analysis of a part of the mitochondrial D-loop region.

Mitochondrial DNA sequencing illuminates genetic diversity and origin of Hunagrian Nonius horse breed and his relatives - Danubian horse and Serbian Nonius.

From a historical perspective, horse breeding in Bulgaria has been very well developed since the time of the Thracians (early Bronze Age c. 3000 BCE). Archaeological discoveries from this era present us with an extremely rich type diversity, including wild and local primitive horses, the prototype of heavy draft horses, and fine riding horses.

Genetic Diversity and Structure of the Main Danubian Horse Paternal Genealogical Lineages Based on Microsatellite Genotyping.

The Danubian horse, together with the Pleven and the Eastern Bulgarian horse breeds, is one of the modern breeds in Bulgaria. The objective of this study was to compare the genetic structure and genetic diversity of six paternal genealogical lineages of the Danubian horse breed (Zdravko, NONIUS XVII-30, Torpedo, Lider, Kalifa, and Hrabar). In total, 166 individuals from the six genealogical lines were investigated, based on 15 STR markers (short tandem repeats, also known as microsatellites).

The Sequence Analysis of Mitochondrial DNA Revealed Some Major Centers of Horse Domestications: The Archaeologist's Cut.

The question about the time and the place of horse domestication, a process which had a profound impact on the progress of mankind, is disputable. According to the most widely accepted hypothesis, the earliest domestication of the horse happened in the western parts of the Eurasian steppes, between the Northern Black Sea region and present-day Kazakhstan and Turkmenistan. It seems that it occurred not earlier than the first half and most probably during the middle (even the last third) of the fourth millennium BC (from ∼ 5.

Sequence analysis of the mitochondrial D-loop region throws a new light on the origin of Hungarian Nonius, Danubian Horse and Serbian Nonius.

The objective of our study was to investigate the genetic structure of yet uninvestigated populations of three closely related horse breeds - the Danubian Horse, the Hungarian Nonius and the Serbian Nonius - in order to clarify their origin and genetic diversity. A 640-bp-long fragment of the mtDNA D-loop region was amplified and sequenced. The results showed that the investigated breeds have different genetic profiles although they share some common characteristics.
