Chromosomal fusions shaped the genome of the greater hornwrack bryozoan (Flustra foliacea) (Linnaeus, 1758)

Helle Tessand Baalsrud, Ole K. Tørresen, Bram Danneels, Giada Ferrari, Ave Tooming‐Klunderud, Morten Skage, S Kollias, Mariann Árnyasi, Erling Svensen, Piotr Kukliński, Kjetill S. Jakobsen, Lee Hsiang Liow

The paper presents the first chromosome-level genome assembly of Flustra foliacea and identifies chromosomal fusions and retrotransposon enrichment in its genome.
