Updated on Sept. 21, 2026 in Life Sciences

Scientists have successfully generated a comprehensive, chromosome-level genome assembly for the hybrid grouper. This research utilized advanced sequencing technology to map the complex genetic structure of the species.
Why it matters
This high-quality reference genome establishes a crucial foundation for future comparative genomics. It will specifically support molecular breeding efforts to enhance traits in grouper populations.
The assembly features a contig N50 of 45.74 Mb across 89 contigs, anchoring 1.08 Gb of sequence to 24 chromosomes. It includes 28,310 identified protein-coding gene models and reveals that repetitive sequences occupy 44.24% of the genome.
The details
The project utilized 5,951,738 PacBio HiFi sequencing reads to generate a total sequence length of 122.82 Gb. These data were compiled into a primary assembly spanning 1.12 Gb, evaluated for completeness through BUSCO analysis.
