The giant panda (Ailuropoda melanoleuca) is a bear native to south central China. For many decades, the precise taxonomic classification of the giant panda was under debate because it shares characteristics with both bears and raccoons. However, molecular studies indicate the giant panda is a true bear, part of the family Ursidae. These studies show it differentiated early (about 19 million years ago) from the main ursine stock; since it is the most basal member of the group, it is equidistant from all other extant ursids. The giant panda has been referred to as a living fossil.
ailMel1 (GCA_000004335.1) is an assembly of the giant panda, sequenced using a three-year-old female panda at China's Chengdu breeding center. The genome sequencing and assembly are provided by the Bejing Genomics Institute (BGI).
The N50 size is the length such that 50% of the assembled genome lies in blocks of the N50 size or longer. The N50 size of the scaffolds is 1.3Mb. The total length of all scaffolds is 2.3Gb, for a genome size estimated to be 2.4Gb.
The gene set for panda was built using the Ensembl pipeline. Gene models are based on genewise alignments of mammal proteins as well as genetically distance proteins from other species, including most vertebrate proteins from Uniprot. Additionally, dog and human proteins were aligned using exonerate.
Potentially missing predictions and partial gene predictions were identified by examining the orthologs, which were then used to build new gene models.
General information about this species can be found in Wikipedia.
