Draft genome of the leopard gecko, Eublepharis macularius

Area of Science:

• Reptile genomics
• Comparative genomics
• Evolutionary biology

Background:

• Geckos are a diverse reptile group, with most species sharing traits like adhesive digits and lacking eyelids.
• The Eublepharidae family, including the leopard gecko, presents exceptions with features like eyelids and soft eggshells.
• Studying Eublepharidae genomes is crucial for understanding genomic innovations in geckos.

Purpose of the Study:

• To perform high-depth genome sequencing, assembly, and annotation of the leopard gecko (Eublepharis macularius).
• To provide a genomic resource for comparative studies within geckos and other squamate reptiles.
• To investigate the genetic basis of unique Eublepharidae phenotypes.

Main Methods:

• High-depth genome sequencing using Illumina technology with seven insert libraries.
• Genome assembly and annotation, yielding a 2.02 Gb genome with 24,755 protein-coding genes.
• Quality assessment using CEGMA and BUSCO to evaluate gene content completeness.

Main Results:

• A high-quality genome assembly of the leopard gecko was produced.
• The assembly captured a significant portion of core eukaryotic and vertebrate genes.
• Repetitive elements constituted 42% of the assembled genome.

Conclusions:

• The leopard gecko genome assembly is a valuable resource for future research.
• Facilitates comparative genomic studies of geckos and squamate reptiles.
• Aids in understanding the genomic underpinnings of phenotypic diversity in geckos.
