| Summary: | Abstract The Pacific whiteleg shrimp (Penaeus vannamei, synonym Lipopenaeus vannamei) is an important aquaculture species, and its breeding improvement relies heavily on high-quality genomic resources. Here, we sequenced the genome of the Pacific whiteleg shrimp using PacBio and Hi-C technologies, resulting in a 1.7 Gb genome assembly with a Contig N50 of 57.65Kb and a Scaffold N50 of 605Kb.BUSCO analysis indicated that our genome assembly achieved a gene coverage of 84.6%, a figure considered high among crustacean reference genomes. In total, 907,237,377 bp of repetitive sequences (accounting for 50.48% of the assembled genome) and 22,923 protein-coding genes were identified. Utilizing Hi-C technology, we anchored 14,604 contigs onto 44 chromosomes, yielding a chromosome-level genome assembly with a contig N50 of 42,894,961 bp. In summary, our high-quality genome assembly provides valuable reference genomic resources for the improvement and breeding of elite cultivars of the Pacific whiteleg shrimp. |
