Chromosome-Scale Genome Assembly of the Freshwater Snail Semisulcospira habei from the Lake Biwa Drainage System.

ABSTRACT: Semisulcospira habei is a freshwater snail species endemic to the Lake Biwa drainage and belongs to a species group radiated within the lake system. We report the chromosome-scale genome assembly of S. habei, including eight megascaffolds larger than 150 Mb. The genome assembly size is about 2.0 Gb with an N50 of 237 Mb. There are 41,547 protein-coding genes modeled by ab initio gene prediction based on the transcriptome data set, and the BUSCO completeness of the annotated genes was 92.2%. The repeat elements comprise approximately 76% of the genome assembly. The Hi-C contact map showed seven well-resolved scaffolds that correspond to the basic haploid chromosome number of S. habei inferred from the preceding karyotypic study, while it also exhibited one scaffold with a complicated mosaic
