Species belonging to (Ulvophyceae, Chlorophyta) are one of the major members of invasive seaweeds. Wille 1899 was originally believed to be native to the Pacific coast of North America, while in recent years it has been reported as exotic species, or new record, in Europe, the Mediterranean, Asia, and Oceania. However, the paths of global dispersal of are unclear. In addition, the species boundary between and a related species is somewhat disputed. Here, we reported that the complete chloroplast genome of is 92,126 bp in size, harboring 96 genes (GenBank accession no. MZ561475). The overall base composition was A (37.9%), T (37.4%), C (12.3%), and G (12.4%), similar to those from other species. The phylogenomic analysis showed that although was genetically closer to (Bliding) Maggs 2018 in [Krupnik N et al., 2018], they were clearly distinguishable, supporting the recent opinion that they should be separated into different species. The chloroplast genome data of would provide plenty resources for phylogeography analysis and monitor on bioinvasion.
属于（绿藻门石莼纲）的物种是入侵海藻的主要成员之一。1899年的威廉藻最初被认为原产于北美太平洋沿岸，而近年来在欧洲、地中海、亚洲和大洋洲被报道为外来物种或新记录物种。然而，威廉藻的全球传播路径尚不清楚。此外，威廉藻与一个近缘物种之间的物种界限也存在一定争议。在此，我们报道威廉藻的完整叶绿体基因组大小为92,126 bp，包含96个基因（GenBank登录号：MZ561475）。总体碱基组成为A（37.9%）、T（37.4%）、C（12.3%）和G（12.4%），与其他威廉藻物种相似。系统基因组分析表明，尽管在[克鲁普尼克N等人，2018年]中威廉藻在基因上与2018年的（布利丁）马格斯藻更接近，但它们明显可区分，支持了最近认为它们应分为不同物种的观点。威廉藻的叶绿体基因组数据将为系统地理学分析和生物入侵监测提供丰富资源。
