Abstract：
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.
摘要：
最近加强了保护稀有和濒危水生物种的保护工作。然而，华丽的多刺龙虾（Panulirusornatus），这在印度太平洋水域很普遍，在很大程度上被忽视了。在没有详细基因组参考的情况下，对这种甲壳类动物的保护和种群遗传学了解甚少。这里,我们为P.ornatus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基因组之一，跨越2.65Gb，重叠群N50为51.05Mb，99.11%的序列整合到73条染色体上。华丽的多刺龙虾基因组包含65.67％的重复序列和22,752个蛋白质编码基因，其中99.20％的基因进行了功能注释。P.ornatus基因组的组装为比较甲壳类基因组学和濒危物种保护提供了有价值的见解，并为未来的物种形成研究奠定了基础，生态学,和华丽的多刺龙虾的进化。
