Tiger (PanTig1.0)

Tiger assembly and gene annotation

The Siberian tiger (Panthera tigris altaica), also called the Amur tiger, is a tiger population inhabiting mainly the Sikhote Alin mountain region in southwest Primorye Province in the Russian Far East, though it once ranged throughout Korea, Northeast China, Russian Far East, and eastern Mongolia.

Assembly

The PanTig1.0 assembly was submitted by Personal Genomics Institute on 2013/09/06 . The assembly is on the Scaffold level, consisting of 157,032 assembled into 1,479 scaffolds. The N50 size is the length such that 50% of the assembled genome lies in blocks of the N50 size or longer. The N50 length for the contigs is 30,032 while the scaffold N50 is 8,860,407.

Gene annotation

The gene annotation process was carried out using a combination of protein-to-genome alignments, annotation mapping from a suitable reference species and RNA-seq alignments (where RNA-seq data with appropriate meta data were publicly available). For each candidate gene region, a selection process was applied to choose the most appropriate set of transcripts based on evolutionary distance, experimental evidence for the source data and quality of the alignments. Small ncRNAs were obtained using a combination of BLAST and Infernal/RNAfold. Pseudogenes were calculated by looking at genes with a large percentage of non-biological introns (introns of <10bp), where the gene was covered in repeats, or where the gene was single exon and evidence of a functional multi-exon paralog was found elsewhere in the genome. lincRNAs were generated via RNA-seq data where no evidence of protein homology or protein domains could be found in the transcript.

In accordance with the Fort Lauderdale Agreement , please check the publication status of the genome/assembly before publishing any genome-wide analyses using these data.
