- The chromosomal-level genome assembly and annotation of pen shell Atrina pectinata. Li, Zhuanzhuan Liu, Bo Chen, Xi Ren, Jianfeng Ma, Peizhen Liu, Zhihong Sun, Xiujun Zhou, Liqing Wu, Biao Zheng, Yanxin Yu, Tao Animals Genome Chromosomes Molecular Sequence Annotation Bivalvia The pen shell Atrina pectinata is a bivalve recognized for its outstanding large adductor muscle and developed byssus. Now, it becomes threatened in East Asia, requiring special attention for artificial breeding to boost yield. However, the lack of high-quality genomes hinders our understanding of its reproductive biology, which resulting in the artificial breeding in pen shell is still a scientific technological problem. Here, we produced a high-quality chromosome-level genome assembly of A. pectinata combing the PacBio, Illumina, and high-resolution chromosome conformation capture sequencing. The final assembly has a size of 951.01 Mb with a scaffold N50 of 52.64 Mb, 98.87% of sequence was anchored onto 17 chromosomes, with a BUSCO evaluation integrity score of 98.8%. We successfully identified 29,326 protein-coding genes and 24,708 genes (84.25%) were functionally annotated. The BUSCO evaluation integrity score for the predicted protein-coding genes was 97.7%. This work promotes the applicability of the A. pectinata genome, laying a solid foundation for future investigations into genomics and biology within this species.
