Marbled Teal Chromosome-Level Genome Assembly and Annotation

A 1.15 Gb chromosome-level genome assembly for the threatened marbled teal (Marmaronetta angustirostris), generated by Joaquin Ortego and published on figshare in 2026. The assembly was created using PacBio HiFi long reads and Omni-C data, with 97.16% anchored into 36 chromosome-scale scaffolds. It contains 16,048 predicted protein-coding genes and supports genome-wide conservation analyses.

Use Cases

• Analyzing patterns of inbreeding and functional genetic variation based on the chromosome-level reference genome.
• Studying demographic history and population structure based on the anchored chromosome scaffolds.
• Supporting evidence-based in situ and ex situ conservation strategies based on the genome-wide data.
• Performing comparative genomics with other avian species based on the 16,048 annotated protein-coding genes.

Strengths

• Chromosome-level assembly with a scaffold N50 of 76.95 Mb.
• High completeness with 99.2% of conserved avian genes recovered in BUSCO analysis.
• 97.16% of the 1.15 Gb assembly is anchored into 36 chromosome-scale scaffolds, including sex chromosomes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain analyses.
