Gaithersburg, Md.December 23, 2012 OpGen, Inc. today announced its ARGUS Whole Genome Mapping System technology was used in combination with next-generation sequencing (NGS) to produce the first, high-quality reference genome of the domestic goat. The study, which was led by BGI-Shenzhen and Kunming Institute of Zoology, Chinese Academy of Sciences was published online today in Nature Biotechnology. The paper, titled Sequencing and automated whole-genome optical mapping of the genome of a domestic goat (Capra hircus), demonstrates the value, efficiency and cost effectiveness of OpGen's Whole Genome Mapping in de novo assemblies of large, complex genomes.
"This independent technology provides not only the validation of the genome sequencing, but also provides the large-scale chromosome structure information that cannot be detected by sequencing," said Xun Xu, Deputy Director, BGI-Shenzhen. "The experience in these genome assembly projects shows that the physical whole genome map should be the standard for any reference genome to be assembled in the future."
Goats are an important economic resource in many developing countries around the globe, including China and India. However, despite their agricultural and biological importance, breeding and genetic studies of goats have been hindered by the lack of a high-quality reference genome sequence. The goat genome is the first high-quality reference genome for small ruminate animals and may help to advance the understanding of distinct ruminant genomic features from non-ruminant species.
Although generating draft assemblies from NGS is relatively easy, finishing a sequence to the chromosome level is still difficult and costly. The findings show that a single NGS platform, when combined with Whole Genome Mapping, can produce a finished assembly much faster and less expensively than other currently available mapping strategi
