The California ribbed mussel, Mytilus californianus, is an ecosystem engineer crucial for the survival of many marine species inhabiting the intertidal zone of California. Here, we describe the first reference genome for M. californianus and compare it to previously published genomes from three other Mytilus species: M. edulis, M. coruscus, and M. galloprovincialis. The M. californianus reference genome is 1.65 Gb in length, with N50 sequence length of 118 Mb, and an estimated 86.0% complete single copy genes. Compared with the other three Mytilus species, the M. californianus genome assembly is the longest, has the highest N50 value, and the highest percentage complete single copy genes. This high-quality genome assembly provides a foundation for population genetic analyses that will give insight into future conservation work along the coast of California.
加利福尼亚贻贝，Mytilus californianus，是一种生态系统工程师，对栖息在加利福尼亚潮间带的许多海洋物种的生存至关重要。在这里，我们描述了第一个 M. californianus 的参考基因组，并将其与之前发表的来自其他三个贻贝物种的基因组进行了比较：M. edulis、M. coruscus 和 M. galloprovincialis。M. californianus 的参考基因组长 1.65 Gb，N50 序列长度为 118 Mb，估计有 86.0%完整的单拷贝基因。与其他三个贻贝物种相比，M. californianus 的基因组组装最长，N50 值最高，完整的单拷贝基因比例最高。这个高质量的基因组组装为群体遗传分析提供了基础，这将为未来在加利福尼亚沿海地区的保护工作提供深入的了解。
