Recent conservation efforts to protect rare and endangered aquatic species have intensified. Nevertheless, the ornate spiny lobster (Panulirus ornatus), which is prevalent in the Indo-Pacific waters, has been largely ignored. In the absence of a detailed genomic reference, the conservation and population genetics of this crustacean are poorly understood. Here, We assembled a comprehensive chromosome-level genome for P. ornatus. This genome-among the most detailed for lobsters-spans 2.65 Gb with a contig N50 of 51.05 Mb, and 99.11% of the sequences with incorporated to 73 chromosomes. The ornate spiny lobster genome comprises 65.67% repeat sequences and 22,752 protein-coding genes with 99.20% of the genes functionally annotated. The assembly of the P. ornatus genome provides valuable insights into comparative crustacean genomics and endangered species conservation, and lays the groundwork for future research on the speciation, ecology, and evolution of the ornate spiny lobster.
最近，保护珍稀濒危水生物种的努力有所加强。然而，在印度洋-太平洋水域广泛存在的华丽棘皮龙虾（Panulirus ornatus）却在很大程度上被忽视了。由于缺乏详细的基因组参考，这种甲壳类动物的保护和种群遗传学还知之甚少。在这里，我们为华丽棘皮龙虾组装了一个全面的染色体水平基因组。这个基因组是龙虾中最详细的之一，跨度为 26.5 亿碱基对，其 contig N50 为 51.05Mb，99.11%的序列整合到 73 条染色体中。华丽棘皮龙虾的基因组包含 65.67%的重复序列和 22752 个蛋白质编码基因，其中 99.20%的基因具有功能注释。华丽棘皮龙虾基因组的组装为比较甲壳动物基因组学和濒危物种保护提供了有价值的见解，并为未来研究华丽棘皮龙虾的物种形成、生态学和进化奠定了基础。
