Nanorana parkeri (also known as the high Himalaya frog, Xizang Plateau frog, Parker's slow frog, or mountain slow frog) is a common frog living across the Tibetan Plateau. It occurs at elevations ranging from 2,850 to 5,000m. Because this species lives at such high elevations, it provides an additional excellent biological model to study the frog’s adaptations to extreme conditions.
A female frog was collected from the Qinghai-Tibetan Plateau at an elevation of 4,900m, and genomic DNA was extracted from muscle tissue. Paired end DNA libraries with different insert-size lengths (170 bp to 20 kb) were sequenced on the Illumina HiSeq 2000 platform. After performing filtering steps to remove artificial duplication, adapter contamination and low-quality reads, 190 Gbp of high-quality data (83× genome coverage) was obtained. This was assembled using SOAPdenovo and SSPACE, producing a final draft assembly of 2.0Gb with an N50 scaffold size of 1.05Mb. More than 20,000 genes were predicted. The Nanorana parkeri genome should help offer new insights into the amphibian evolution and Tibetan high-altitude adaptation.
