Molecular phylogeny of the neotropical genus Christensonella (Orchidaceae, Maxillariinae): species delimitation and insights into chromosome evolution.
BACKGROUND AND AIMS Species' boundaries applied within Christensonella have varied due to the continuous pattern of variation and mosaic distribution of diagnostic characters. The main goals of this study were to revise the species' delimitation and propose a more stable classification for this genus. In order to achieve these aims phylogenetic relationships were inferred using DNA sequence dat...
متن کاملDactylorhiza (Orchidaceae) in European Russia: combined molecular and morphological analysis.
Four plastid and two nuclear (internal transcribed spacer [ITS] ribosomal DNA) markers were used in this study of the Dactylorhiza maculata and D. incarnata complexes (Orchidaceae: Orchidinae) to determine diversity and taxonomic distribution of haplotypes, hybridization frequencies, and maternal parentage of hybrids in 125 samples from 78 populations from European Russia and the Caucasus. A mo...
متن کاملPaleontology, genomics, and combined-data phylogenetics: can molecular data improve phylogeny estimation for fossil taxa?
The genomics revolution offers great promise for resolving the phylogeny of living taxa, but does it offer any benefits for reconstructing relationships among extinct (fossil) taxa? Superficially, the answer would seem to be "no," given that molecular data cannot be obtained for most fossil taxa. However, because fossil taxa often interdigitate among living taxa on the Tree of Life, molecular d...
متن کاملMolecular phylogenetics and the evolution of fruit and leaf morphology of Dichaea (Orchidaceae: Zygopetalinae).
BACKGROUND AND AIMS The orchid genus Dichaea, with over 100 species found throughout the neotropics, is easily recognized by distichous leaves on long stems without pseudobulbs and flowers with infrastigmatic ligules. The genus has previously been divided into four sections based primarily on presence of ovary bristles and a foliar abscission layer. The aim of this work is to use DNA sequence d...
متن کاملMolecular Phylogenetics and Evolution
The freshwater mussel family Hyriidae (Mollusca: Bivalvia: Unionida) has a disjunct trans-Pacific distribution in Australasia and South America. Previous phylogenetic analyses have estimated the evolutionary relationships of the family and the major infra-familial taxa (Velesunioninae and Hyriinae: Hyridellini in Australia; Hyriinae: Hyriini, Castaliini, and Rhipidodontini in South America), bu...
