Researchers have sequenced the genome of a Bactrian camel named Mozart, laying down the foundation for future scientific work on these large desert mammals.

Camels consist of two species, which include the one-humped dromedary and the two-humped Bactrian camel. The animals have the ability to carry heavy loads in harsh desert environments over long distances. They can survive weeks in hostile environments without food or water. Researchers at the Vetmeduni Vienna wanted to learn a bit more about the genetic code of the camel.

Researcher Pamela Burger, who heads one of the few research groups to study camel genetics, was interested in learning about the domestication of camels which took place around 3,000 to 6,000 years ago. Burger and her colleagues believe that the animals DNA code could provide clues on the breeding strategies and selection processes that were applied by humans at that time.

The scientists found 116,000 single nucleotide polymorphisms (SNPs) in the genetic sequence of the Bactrian camel. SNPs are single base-pair changes found in a DNA strand that provide the basis for studying relationships among species and between single animals. The genetic relationship between the Bactrian camel and the dromedary camel is a close one. They found that 85 percent of the genomic sequence expressed in the dromedary can be found in the Bactrian camel as well.

Mozarts genome provides us with the basis for further comparative research on other camelids such as dromedary, lama and alpaca, said Burger, who also authored the study which appeared in the Journal of Heredity.

The lack of basic genetic data on camel species has hampered researchers like Burger from studying the animals genome. These genomes will also help scientists understand more about the evolution of the camel and its predecessors, such as how one recently discovered 3.5-million-year-old fossil may have played into its evolutionary family tree.

In March, researchers discovered the fossilized remains of a giant prehistoric species of camel in the far northern regions of Canada. The discovery implies that modern camels are descendants from ancestors which lived within the Canadian Arctic Circle. The paleontologists found 30 fossil fragments of a leg bone that dates back to the mid-Pliocene Epoch period. They believe the creature would have been similar in appearance to current camels, but with a thicker coat to keep it warm.

We now have a new fossil record to better understand camel evolution, since our research shows that the Paracamelus lineage inhabited northern North America for millions of years, and the simplest explanation for this pattern would be that Paracamelus originated there, explained paleontologist Dr. Natalia Rybczynski of the Canadian Museum of Nature.

Decoded Camel Genome To Unveil Secrets Of Evolutionary History

May 28, 2013 By sequencing the genome of a Bactrian camel, researchers at the Vetmeduni Vienna have made a significant contribution to population genetic research on camels. The study has laid the foundation for future scientific work on these enigmatic desert animals. A blood sample from a single Bactrian camel with the evocative name of "Mozart" provided the genetic raw material for the work, which was undertaken by Pamela Burger at the Institute of Population Genetics.

Camels are divided into two species, the one-humped dromedary and the two-humped Bactrian camel. Whether equipped with one or two humps, camels are precious in desert regions throughout the world. Their ability to carry heavy loads over long distances makes them ideally suited for transportation. In addition, camels are able to survive for weeks in hostile environments without food and water. Despite the extremely arid conditions, camels still provide enough milk for human consumption and also have an important role as a source of meat. Camels are specialists when it comes to adapting to the environment and have been characterized as sustainable food producers.

Focusing on camel domestication

Pamela Burger heads one of the few research groups in Europe that study camel genetics. Burger and her colleagues are primarily interested in the domestication of camels, which took place around 3,000 to 6,000 years ago. Genetic data provide important clues on the breeding strategies and selection processes that were applied by humans at that time. The DNA code also represents a rich resource for addressing questions on phylogenetic relationships between animals. Burger is one of the first scientists to sequence large parts of the genome of a Bactrian camel and make it available to the public.

Milestone in camel genetics

Until recently, the genetic code of the Camel had not been fully analysed. Genetic research on these animals was therefore difficult or even impossible. In contrast, the entire genetic information of the human genome was available as long ago as 2003 and the genetic code of various animals and plants is publicly available, giving researchers access to an enormous set of data. To date, the lack of basic genetic data has severely hampered studies of camel genetics. Pamela Burger and her team are pioneers in presenting this essential dataset.

Relationship among the one- and the two-humped

The scientists were able to find 116,000 so-called SNPs (single nucleotide polymorphisms) in the genetic sequence of the Bactrian camel. SNPs are single base-pair changes within a DNA strand that provide the basis for studying relationships among species and between single animals. The genetic relationship between the Bactrian camel (Camelus bactrianus) and the dromedary (Camelus dromedarius) is close. 85 per cent of the genomic sequences expressed in the dromedary can be found in the Bactrian camel. Burger explains, "Mozart's genome provides us with the basis for further comparative research on other camelids such as dromedary, lama and alpaca."
