Data from: De novo assembly of a chromosome-level reference genome of red spotted grouper (Epinephelus akaara) using nanopore sequencing and Hi-C
The red spotted grouper Epinephelus akaara (E. akaara) is one of the most economically important marine fish in China, Japan and Southeast Asia, and is a threatened species. The species is also considered a good model for studies of sex-inversion, development, genetic diversity and immunity. Despite its importance, molecular resources for E. akaara remain limited and no reference genome has been published to date. In this study, we constructed a chromosome-level reference genome of E. akaara by taking advantage of long-read single molecule sequencing and de novo assembly by Oxford Nanopore Technologies (ONT) and Hi-C. A red-spotted grouper genome of 1.135 Gb was assembled from a total of 106.29 Gb polished Nanopore sequence (GridION, ONT), equivalent to 96-fold genome coverage. The assembled genome represents 96.8% completeness (BUSCO) with a contig N50 length of 5.25 Mb and a longest contig of 25.75 Mb. The contigs were clustered and ordered onto 24 pseudo-chromosomes covering approximately 95.55% of the genome assembly with Hi-C data, with a scaffold N50 length of 46.03 Mb. The genome contained 43.02% repeat sequences and 5,480 non-coding RNAs. Furthermore, after mining several RNA-seq datasets, 23,809 (99.5%) genes were functionally annotated from a total of 23,924 predicted protein-coding sequences. The high-quality chromosome-level reference genome of E. akaara was assembled for the first time and will be a valuable resource for molecular breeding and functional genomics studies of red-spotted grouper in the future.
