Abstract

The ivory shell Babylonia areolata is an economically important marine benthic gastropod known for its rapid growth and high nutritional value. B. areolata is distributed in Southeast Asia and the southeast coastal areas of China. In this study, we constructed a high-quality genome for B. areolata using PacBio, Illumina, and Hi-C sequencing technologies. The genome assembly comprised 35 chromosomal sequences with a total length of 1.65 Gb. The scaffold and contig N50 lengths were 53.17 Mb and 2.64 Mb, respectively, with repeat sequences constituting 64.46% of the genome. Furthermore, 26,130 protein-coding genes and 96.75% of the genome's BUSCOs were identified. This inaugural report of a B. areolata genome provides crucial foundational information for further investigations into the biology, genomics, and genetic improvement of economic traits of this species.

摘要

宝螺科宝贝贝（Babylonia areolata）是一种经济价值很高的海洋底栖腹足纲动物，以其快速生长和高营养价值而闻名。B. areolata 分布于东南亚和中国东南沿海地区。在这项研究中，我们使用 PacBio、Illumina 和 Hi-C 测序技术为 B. areolata 构建了一个高质量的基因组。基因组组装由 35 条染色体序列组成，总长度为 16.5Gb。支架和 contig N50 长度分别为 53.17Mb 和 2.64Mb，基因组中重复序列占 64.46%。此外，鉴定出了 26130 个蛋白质编码基因和 96.75%的基因组 BUSCOs。这是对 B. areolata 基因组的首次报道，为进一步研究该物种的生物学、基因组学和遗传改良经济性状提供了重要的基础信息。
