Variation in the mitochondrial control region sequence between the two maternal lines of the Sorraia horse breed
نویسندگان
چکیده
The mitochondrial control region sequence was compared between the two surviving matrilineal lineages of the Sorraia horse. Two haplotypes were found, showing three differences between them. The reduced number of surviving maternal lineages emphasizes the importance of establishing a conservation plan for this endangered breed.

Mitochondrial DNA D-loop sequence variation among 5 maternal lines of the Zemaitukai horse breed
Genetic variation in Zemaitukai horses was investigated using mitochondrial DNA (mtDNA) sequencing. The study was performed on 421 bp of the mitochondrial DNA control region, which is known to be more variable than other sections of the mitochondrial genome. Samples from each of the remaining maternal family lines of Zemaitukai horses and three random samples for other Lithuanian (Lithuanian He...
متن کاملInbreeding and genetic structure in the endangered Sorraia horse breed: implications for its conservation and management.
The Sorraia horse is a closed breed with reduced effective population size and considered in critical maintained risk status. The breed exists in 2 main breeding populations, one in Portugal and one in Germany, with a smaller population size. A set of 22 microsatellite loci was used to examine genetic diversity and structure of the Sorraia horse breed and to compare individual inbreeding coeffi...
متن کاملThe Lusitano horse maternal lineage based on mitochondrial D-loop sequence variation.
The analysis of mitochondrial D-loop sequences (408 bp) from 145 Lusitano founder mares yielded a total of 27 different haplotypes. The distribution of these mtDNA sequences was quite unequal, with the three most frequent ones representing 56.5% of all the Lusitano founder mares and 14 haplotypes (51.9%) being rare variants found only once in the sampling. Four main haplotype clusters were pres...
متن کاملCharacterization of the Polish Primitive Horse (Konik) maternal lines using mitochondrial D-loop sequence variation
The Polish Primitive Horse (PPH, Konik) is a Polish native horse breed managed through a conservation program mainly due to its characteristic phenotype of a primitive horse. One of the most important goals of PPH breeding strategy is the preservation and equal development of all existing maternal lines. However, until now there was no investigation into the real genetic diversity of 16 recogni...
متن کاملSequence Variations of Mitochondrial DNA Displacement-Loop in Iranian Indigenous Sheep Breeds
Mitochondrial DNA (mtDNA) has been used extensively to study population genetics because it has the unique features of maternal inheritance, a relatively fast rate of evolution and lack of recombination. A total of 82 unrelated sheep from 10 Iranian indigenous sheep breeds were investigated to determinate the maternal genetic diversity using a sequence of a 685 bp segment of the displacement lo...
