    Phylogenies, polyploidization events, and hybridization events: some of my favorite things.

    I have a copy of this from research gate, so it is available, but it is an “uncorrected proof”.

     

    Abstract:

    Cyprininae is the largest subfamily (>1300 species) of the family Cyprinidae and contains more polyploid 39
    species (400) than any other group of fishes. We examined the phylogenetic relationships of the Cypri- 40
    ninae based on extensive taxon, geographical, and genomic sampling of the taxa, using both mitochon- 41
    drial and nuclear genes to address the phylogenetic challenges posed by polyploidy. Four datasets 42
    were analyzed in this study: two mitochondrial gene datasets (465 and 791 taxa, 5604 bp), amitogenome 43
    dataset (85 taxa, 14,771 bp), and a cloned nuclear RAG1 dataset (97 taxa, 1497 bp). Based on resulting 44
    trees, the subfamily Cyprininae was subdivided into 11 tribes: Probarbini (new; Probarbus + Catlocarpio), 45
    Labeonini Bleeker, 1859 (Labeo & allies), Torini Karaman, 1971 (Tor, Labeobarbus & allies), Smiliogastrini 46
    Bleeker, 1863 (Puntius, Enteromius & allies), Poropuntiini (Poropuntius & allies), Cyprinini Rafinesque, 47
    1815 (Cyprinus & allies), Acrossocheilini (new; Acrossocheilus & allies), Spinibarbini (new; Spinibarbus), 48
    Schizothoracini McClelland, 1842 (Schizothorax & allies), Schizopygopsini Mirza, 1991 (Schizopygopsis & 49
    allies), and Barbini Bleeker, 1859 (Barbus & allies). Phylogenetic relationships within each tribe were dis- 50
    cussed. Two or three distinct RAG1 lineages were identified for each of the following tribes Torini, Cypri- 51
    nini, Spinibarbini, and Barbini, indicating their hybrid origin. The hexaploid African Labeobarbus & allies 52
    and Western Asian Capoeta are likely derived from two independent hybridization events between their 53
    respective maternal tetraploid ancestors and Cyprinion.

    I’d love a copy please Bill.
