Complete chloroplast genome of an invasive marine macroalga (Ulvophyceae, Chlorophyta).

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.
