Chromosome-level Genome Assembly and Annotation of Potato Grouper
Researchers have published a high-quality, chromosome-level genome assembly and annotation for the potato grouper (Epinephelus tukula), an economically significant aquaculture species known for its rapid growth. Although previous genomic reports existed, they suffered from a large proportion of unanchored scaffolds. This study utilized PacBio HiFi sequencing and Hi-C technology to produce an improved assembly totaling 1.108 Gb, with a contig N50 of 41.91 Mb and a scaffold N50 of 46.58 Mb. Approximately 99.53% of the assembly was successfully anchored onto 24 chromosomes, achieving a BUSCO completeness estimate of 98.1%. The team predicted 25,028 protein-coding genes, functionally annotating 98.77% of them. This comprehensive reference genome serves as a critical resource for future genetic breeding programs, population genomics studies, and the exploration of functional genes associated with important traits in potato grouper. The research was supported by various Chinese scientific foundations and institutions, highlighting advancements in marine biotechnology and aquaculture science.
