Genome assembly of a triploid <i>Pocillopora acuta</i>

This study details the genome assembly of the Hawaiian coral species <i>Pocillopora acuta</i>. Members of this genus are distributed worldwide and therefore of broad scientific and ecological importance. For <i>Poc. acuta</i>, a high-quality assembly was generated using short-read Illumina and long-read PacBio data. The <i>Poc. acuta</i> assembly is from a triploid individual, making it the first reference genome of a non-diploid coral animal. This genome assembly is a significant improvement over available data and provides an invaluable resource for supporting multi-omics studies into coral biology, not just in Hawaii, but also in other regions, where related species exist. The <i>Poc. acuta</i> assembly gives us, for the first time, a platform for studying polyploidy in corals, and its role in genome evolution and stress adaptation in these organisms.

本研究详细报道了夏威夷珊瑚物种<em>Pocillopora acuta</em>的基因组组装工作。该属珊瑚广泛分布于全球，因此具备广泛的科学与生态学研究价值。针对<em>Poc. acuta</em>，研究团队结合短读长Illumina测序数据与长读长PacBio测序数据，完成了高质量的基因组组装。本次组装的<em>Poc. acuta</em>基因组来自一个三倍体个体，是全球首个非二倍体珊瑚动物参考基因组。该基因组组装较现有公开数据实现了显著提升，可为全球范围内不仅限于夏威夷且存在近缘珊瑚物种的区域开展珊瑚生物学多组学研究提供宝贵的资源支撑。本次<em>Poc. acuta</em>的基因组组装首次为珊瑚多倍体研究搭建了平台，有助于解析多倍性在珊瑚基因组演化及这类生物的胁迫适应过程中所发挥的作用。
