The Crested Ibis (Nipponia nippon (Temminck, 1855)) is the only member of the genus Nipponia and also known as the Japanese Crested Ibis (Toki). Originally widespread across China, Japan, Korea, Taiwan and Russia, by 1988 the species had disappeared from nearly all these places, except two surviving breeding pairs in Southern Qinling mountains of Yangxian County, China.
DNA was collected from a female that descended from one of these pairs, belonging to a population now rescued from near extinction. We sequenced the 1.6 Gb genome to a depth of approximately 105X with short reads from a series of libraries with various insert sizes (170bp, 500bp, 800bp, 2kb, 5kb, 10kb and 20kb).
The assembled scaffolds of high quality sequences totaled 1.17 Gb, with the contig and scaffold N50 values of 22kb and 5.4Mb respectively. We identified 16,756 protein-coding genes with a mean length of 19.4 kb.
