    The developmental transcriptome of contrasting Arctic charr (Salvelinus alpinus) morphs 
    Guðbrandsson, Jóhannes; Pashay Ahi, Ehsan; Franzdottir, Sigridur Rut; Kapralova, Kalina; Kristjansson, Bjarni K.; Steinhäuser, Sophie S.; Maier, Valerie H.; Johannesson, Isak M.; Snorrason, Sigurður S.; Jonsson, Zophonias O.; Palsson, Arnar (F1000 Research, Ltd., 2016-12-02)
    Species and populations with parallel evolution of specific traits can help illuminate how predictable adaptations and divergence are at the molecular and developmental level. Following the last glacial period, dwarfism and specialized bottom feeding ...

    Differentiation at the MHCIIα and Cath2 Loci in Sympatric Salvelinus alpinus Resource Morphs in Lake Thingvallavatn 
    Kapralova, Kalina; Guðbrandsson, Jóhannes; Reynisdottir, Sigrun; Santos, Cristina B.; Baltanás, Vanessa C; Maier, Valerie H. untranslated; Snorrason, Sigurður S.; Palsson, Arnar (Public Library of Science (PLoS), 2013-07-24)
    Northern freshwater fish may be suitable for the genetic dissection of ecological traits because they invaded new habitats after the last ice age (∼10.000 years ago). Arctic charr (Salvelinus alpinus) colonizing streams and lakes in Iceland gave rise ...

    Functional Evolution of a cis-Regulatory Module 
    Ludwig, Michael Z; Palsson, Arnar; Alekseeva, Elena; Bergman, Casey M; Nathan, Janaki; Kreitman, Martin (Public Library of Science (PLoS), 2005-03-15)
    Lack of knowledge about how regulatory regions evolve in relation to their structure–function may limit the utility of comparative sequence analysis in deciphering cis-regulatory sequences. To address this we applied reverse genetics to carry out a ...

    Naturally Occurring Deletions of Hunchback Binding Sites in the Even-Skipped Stripe 3+7 Enhancer 
    Wesolowska, Natalia; Reynisdóttir, Sigrún; Ludwig, Michael Z.; Kreitman, Martin; Palsson, Arnar (Public Library of Science (PLoS), 2014-05-01)
    Changes in regulatory DNA contribute to phenotypic differences within and between taxa. Comparative studies show that many transcription factor binding sites (TFBS) are conserved between species whereas functional studies reveal that some mutations ...

    Nucleotide Variation in the Egfr Locus of Drosophila melanogaster 
    Palsson, Arnar; Rouse, Ann; Riley-Berger, Rebecca; Dworkin, Ian; Gibson, Greg (Genetics Society of America, 2004-07-01)
    The Epidermal growth factor receptor is an essential gene with diverse pleiotropic roles in development throughout the animal kingdom. Analysis of sequence diversity in 10.9 kb covering the complete coding region and 6.4 kb of potential regulatory ...

    Tests for the replication of an association between Egfr and natural variation in Drosophila melanogaster wing morphology 
    Palsson, Arnar; Dodgson, James; Dworkin, Ian; Gibson, Greg (BioMed Central Ltd, 2005)
    Background Quantitative differences between individuals stem from a combination of genetic and environmental factors, with the heritable variation being shaped by evolutionary forces. Drosophila wing shape has emerged as an attractive system for ...
