Despite causing considerable ecological and economic impacts, there is a surprising void of basic genomic knowledge, and a barnacle reference genome is lacking. We here set out to characterize the genome of the bay barnacle Balanus improvisus (= Amphibalanus improvisus) based on short-read whole-genome sequencing and experimental genome size estimation. We show both experimentally (DNA staining and flow cytometry) and computationally (k-mer analysis) that B. improvisus has a haploid genome size of ~ 740 Mbp. A pilot genome assembly rendered a total assembly size of ~ 600 Mbp and was highly fragmented with an N50 of only 2.2 kbp. Further assembly-based and assembly-free analyses revealed that the very limited assembly contiguity is due to the B. improvisus genome having an extremely high nucleotide diversity (\u03c0) in coding regions (average \u03c0 \u2248 5% and average \u03c0 in fourfold degenerate sites \u2248 20%), and an overall high repeat content (at least 40%). We also report on high variation in the \u03b1-octopamine receptor OctA (average \u03c0 = 3.6%), which might increase the risk that barnacle populations evolve resistance toward antifouling agents. The genomic features described here can help in planning for a future high-quality reference genome, which is urgently needed to properly explore and understand proteins of interest in barnacle biology and marine biotechnology and for developing better antifouling strategies.", "doi": "10.1007/s10126-021-10033-8", "pmid": "33931810", "labels": [], "xrefs": [{"db": "pmc", "key": "PMC8270832"}, {"db": "pii", "key": "10.1007/s10126-021-10033-8"}], "notes": [], "created": "2026-09-23T11:58:45.022Z", "modified": "2026-09-23T11:58:45.156Z"}, {"entity": "publication", "iuid": "b4ef664c54824603baa4310e80004823", "links": {"self": {"href": "https://publications-affiliated.scilifelab.se/publication/b4ef664c54824603baa4310e80004823.json"}, "display": {"href": "https://publications-affiliated.scilifelab.se/publication/b4ef664c54824603baa4310e80004823"}}, "title": "Model communities hint to promiscuous metabolic linkages between ubiquitous free-living freshwater bacteria", "authors": [{"family": "Garcia", "given": "Sarahi L", "initials": "SL", "orcid": "0000-0002-8622-0308", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/df5f980a4dfb4b669961af28a1242f12.json"}}, {"family": "Buck", "given": "Moritz", "initials": "M"}, {"family": "Hamilton", "given": "Joshua J", "initials": "JJ"}, {"family": "Wurzbacher", "given": "Christian", "initials": "C"}, {"family": "Rosenblad", "given": "Magnus Alm", "initials": "MA", "orcid": "0000-0002-4077-7821", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/2fcfdcf342c5438786b4ea9600d2f857.json"}}, {"family": "McMahon", "given": "Katherine D", "initials": "KD", "orcid": "0000-0002-7038-026X", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/65e07397a409477795c29260f2260709.json"}}, {"family": "Grossart", "given": "Hans Peter", "initials": "HP"}, {"family": "Warnecke", "given": "Falk", "initials": "F"}, {"family": "Eiler", "given": "Alexander", "initials": "A", "orcid": "0000-0001-9916-9567", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/3359a98247b849479a1015094c591393.json"}}], "type": "posted-content", "published": "2017-01-28", "journal": {"issn-l": null}, "abstract": null, "doi": "10.1101/103838", "pmid": null, "labels": {"SciLifeLab Fellow": "", "Sarahi Garcia": ""}, "xrefs": [], "notes": [], "created": "2026-09-23T14:18:42.808Z", "modified": "2026-09-23T14:18:42.878Z"}]}
