Here we combine long reads, linked reads and optical mapping to characterize three divergent chromosome regions in the willow warbler Phylloscopus trochilus, of which two are associated with differences in migration and one with an environmental gradient. We show that there are inversions (0.4-13 Mb) in each of the regions and that the divergence times between inverted and non-inverted haplotypes are similar across the regions (~1.2 Myrs), which is compatible with a scenario where inversions arose in either of two allopatric populations that subsequently hybridized. The improved genomes allow us to detect additional functional differences in the divergent regions, providing candidate genes for migration and adaptations to environmental gradients.", "doi": "10.1038/s41467-023-36167-y", "pmid": "36707538", "labels": [], "xrefs": [{"db": "pmc", "key": "PMC9883250"}, {"db": "pii", "key": "10.1038/s41467-023-36167-y"}], "notes": [], "created": "2026-09-23T09:34:28.759Z", "modified": "2026-09-23T09:34:28.847Z"}, {"entity": "publication", "iuid": "1ef5a157559c4219acf21341caca4eff", "links": {"self": {"href": "https://publications-affiliated.scilifelab.se/publication/1ef5a157559c4219acf21341caca4eff.json"}, "display": {"href": "https://publications-affiliated.scilifelab.se/publication/1ef5a157559c4219acf21341caca4eff"}}, "title": "Balancing selection in Pattern Recognition Receptor signalling pathways is associated with gene function and pleiotropy in a wild rodent.", "authors": [{"family": "Lundberg", "given": "Max", "initials": "M", "orcid": "0000-0002-1895-3622", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/624a180a4f184b91ade87d66e304d07c.json"}}, {"family": "Zhong", "given": "Xiuqin", "initials": "X", "orcid": "0000-0002-4772-4255", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/43c7540d78fd4f04aced5298720776ef.json"}}, {"family": "Konrad", "given": "Anna", "initials": "A"}, {"family": "Olsen", "given": "Remi-Andr\u00e9", "initials": "RA"}, {"family": "R\u00e5berg", "given": "Lars", "initials": "L", "orcid": "0000-0001-5219-7448", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/ee130eb9ce934f3387ccd04972e02d47.json"}}], "type": "journal article", "published": "2020-06-00", "journal": {"title": "Mol.

However, the factors that may influence which immune genes are the targets of such selection are largely unknown. To address this, here we focus on Pattern Recognition Receptor (PRR) signalling pathways, which play a key role in innate immunity. We used whole-genome resequencing data from a population of bank voles (Myodes glareolus) to test for associations between balancing selection, pleiotropy and gene function in a set of 123 PRR signalling pathway genes. To investigate the effect of gene function, we compared genes encoding (a) receptors for microbial ligands versus downstream signalling proteins, and (b) receptors recognizing components of microbial cell walls, flagella and capsids versus receptors recognizing features of microbial nucleic acids. Analyses based on the nucleotide diversity of full coding sequences showed that balancing selection primarily targeted receptor genes with a low degree of pleiotropy. Moreover, genes encoding receptors recognizing components of microbial cell walls etc. were more important targets of balancing selection than receptors recognizing nucleic acids. Tests for localized signatures of balancing selection in coding and noncoding sequences showed that such signatures were mostly located in introns, and more evenly distributed among different functional categories of PRR pathway genes. The finding that signatures of balancing selection in full coding sequences primarily occur in receptor genes, in particular those encoding receptors for components of microbial cell walls etc., is consistent with the idea that coevolution between hosts and pathogens is an important cause of balancing selection on immune genes.", "doi": "10.1111/mec.15459", "pmid": "32374503", "labels": [], "xrefs": [{"db": "Dryad", "key": "10.5061/dryad.2bvq83bms"}], "notes": [], "created": "2026-09-23T12:00:39.437Z", "modified": "2026-09-23T12:00:39.556Z"}]}
