Description
  • Phylogenetic relationships among Pinus species from subgenus Strobus remain unresolved despite combined efforts based on nrITS and cpDNA. To provide greater resolution among these taxa, a 900-bp intron from a late embryogenesis was sequenced from 39 pine species. Intraspecific nucleotide diversity was strongly associated with the degree of species monophyly. Although species nonmonophyly complicates phylogenetic interpretations, this nuclear locus offers greater topological support than previously observed for cpDNA or nrITS. Lacking evidence for hybridization, recombination, or imperfect taxonomy, we feel that incomplete lineage sorting remains the best explanation for the polymorphisms shared among species. The absence of allelic coalescence is a severe constraint in the application of phylogenetic methods in Pinus, and taxa sharing similar life history traits with Pinus are likely to show species nonmonophyly using nuclear markers.
