show Abstracthide AbstractThis is an improved genome assembly (v8) for Pungitius pungitius, which contains pseudo-X chromosome (LG12) and a large Y scaffold (LG22; sex-linked region of Y). With the aid of 10x Genomics mapping of a male and a female, more contigs were assigned into linkage groups. New assembly contains 22 LGs and 106 unassigned contigs.
