Chromosome-level genome assembly of the cave leech Sinospelaeobdella cavatuses (Hirudinea: Haemadipsidae).
Leeches are famous for their high medical value and wide environmental adaptability. Among them, cave leeches are a very fascinating and rare group, which is an important component in the study of adaptive evolution of leeches. However, no study has yet reported a reference genome for this group. In this study, we assembled a high-quality chromosome-level genome of the cave terrestrial leech Sinospelaeobdella cavatuses, through Illumina and PacBio sequencing, alongside chromosome conformation capture techniques. The resulting genome spans 153.67 Mb across 9 pseudochromosomes(range: 11.33 to 23.53 Mb), with a mounting rate of up to 95.37% and features an N50 length of 17.15 Mb. This genome is composed of 35.16% repetitive elements and contains 21180 predicted protein-coding genes. Decoding the S. cavatuses genome not only promotes future studies on study of its phylogeny, evolution, and behavior, but also provides valuable resources for in-depth investigation on adaptive evolution of leech.
期刊介绍：
Scientific Data is an open-access journal focused on data, publishing descriptions of research datasets and articles on data sharing across natural sciences, medicine, engineering, and social sciences. Its goal is to enhance the sharing and reuse of scientific data, encourage broader data sharing, and acknowledge those who share their data.
The journal primarily publishes Data Descriptors, which offer detailed descriptions of research datasets, including data collection methods and technical analyses validating data quality. These descriptors aim to facilitate data reuse rather than testing hypotheses or presenting new interpretations, methods, or in-depth analyses.
