Ixodes scapularis (Black-legged tick, PalLabHiFi) (ASM1692078v2)

Ixodes scapularis (Black-legged tick, PalLabHiFi) Assembly and Gene Annotation

The Ixodes scapularis data and its display on Ensembl Genomes are made possible through a joint effort by the Ensembl Genomes group and VectorBase, a component of VEuPathDB.

The assembly name may not match that from INSDC due to additional community contributions applied by VEuPathDB to the initial INSDC assembly (recorded by the assembly accession).
