Chromosome-level genome assembly and annotation of the kuruma shrimp (Marsupenaeus japonicus)

Using PacBio and Hi-C sequencing technology, we assembled a new chromosome-level genome of the kuruma shrimp (Marsupenaeus japonicus), with a total size of 1.64 Gb and scaffold N50 length of 40 613 942 bp. Furthermore, we assembled the 2 381 scaffolds into 43 chromosomes with 1 603 178 927 bp, accounting for 97.83% of the total length. A total of 21 172 protein-coding genes were predicted in the assembled genome, and 83.2% of them were functionally annotated.本研究利用PacBio测序技术与Hi-C测序技术，组装获得了日本囊对虾（kuruma shrimp, Marsupenaeus japonicus）的全新染色体级基因组，总组装长度为1.64 Gb，支架N50长度为40613942 bp。进一步而言，我们将2381个支架锚定至43条染色体，锚定序列总长度达1603178927 bp，占基因组总组装长度的97.83%。该组装基因组中共预测得到21172个蛋白质编码基因，其中83.2%的基因获得了功能注释。
