Anguidae lizard (Ophisaurus gracilis) genome assembly data.
Dataset type: Genomic
Data released on March 30, 2015
The evolutionary transition from a lizard-like body to a snake-like body form is one
of the most important transformations in reptilian evolution. The increasing number of reptilian
genomes allows a deeper understanding of vertebrate evolution, although the genetic basis
underlying the loss of limbs in reptiles remains enigmatic. Here we report the sequencing,
assembly, and annotation of the genome of Asian glass lizard Ophisaurus gracilis, which is a
limbless lizard species with an elongated snake-like body form.
The sequencing of the O. gracilis genome using the Illumina HiSeq2000 platform
resulted in a total of 274.20 Gbp raw data, which was subsequently filtered and assembled to a
final assembly of 1.78 Gbp, comprising 6,717 scaffolds with N50=1.27 Mbp. Based on the k-mer
estimated genome size of 1.71 Gbp, the assembly appears to be near 100% complete. A total of
19,513 protein coding genes were predicted, and 884.06 Mbp repeat sequences (approximately
half of the genome) were annotated. The draft genome of O. gracilis shows similar characteristics
to both lizards and snakes, and represents a substantial addition to existing reptilian genomes
available for comparative analysis.
