摘要	Diatom species of the genus Skeletonema are dominant in global coastal waters with important roles in marine primary production and global biogeochemical cycling. Many Skeletonema species have been extensively studied also because they can cause harmful algae blooms (HABs) with negative impacts on marine ecosystems and aquaculture. In this study, the first chromosome-level assembly of the genome of Skeletonema marinoi was constructed. The genome size was 64.99 Mb with a contig N50 of 1.95 Mb. Up to 97.12 % of contigs were successfully anchored on 24 chromosomes. Analysis of the annotated genes revealed 28 large syntenic blocks with 2397 collinear gene pairs in the genome of S. marinoi, suggesting large-scale segmental duplication events in evolution. Substantial expansion of lightharvesting genes encoding fucoxanthin-chlorophyll a/c binding proteins, as well as expansion of photoreceptor gene families encoding aureochromes and cyptochromes (CRY) in S. marinoi were found, which may have shaped ecological adaptation of S. marinoi. In conclusion, the construction of the first high-quality Skeletonema genome assembly offers valuable clues on the ecological and evolutionary characteristics of this dominant coastal diatom species.
