Sloan, Daniel B, Oxelman, Bengt, Rautenberg, Anja, Taylor, Douglas R
Abstract Background Recent phylogenetic studies have revealed that the mitochondrial genome of the angiosperm Silene noctiflora (Caryophyllaceae) has experienced a massive mutation-driven...
Inferring polyploid phylogenies from multiply-labeled gene trees (2009)
Lott, Martin, Spillner, Andreas, Huber, Katharina T, Petri, Anna, Oxelman, Bengt, Moulton, Vincent
Abstract Background Gene trees that arise in the context of reconstructing the evolutionary history of polyploid species are often multiply-labeled, that is, the same leaf label can occur several...
Frajman, Bozo, Eggens, Frida, Oxelman, Bengt
We used four potentially unlinked nuclear DNA regions from the gene family encoding the second largest subunit of the RNA polymerases, as well as the psbE-petG spacer and the rps16 intron from the...
Conflicting phylogenetic signals in the SlX1/Y1 gene in Silene (2008)
Rautenberg, Anja, Filatov, Dmitry, Svennblad, Bodil, Heidari, Nahid, Oxelman, Bengt
Abstract Background Increasing evidence from DNA sequence data has revealed that phylogenies based on different genes may drastically differ from each other. This may be due to either inter- or...
Britton, Tom, Svennblad, Bodil, Erixon, Per, Oxelman, Bengt
In phylogenetic inference, the support of an estimated phylogenetic tree topology and its interior branches is usually measured either with non-parametric bootstrap support (BS) values or with...
Untangling Complex Histories of Genome Mergings in High Polyploids (2007)
Brysting, Anne K., Oxelman, Bengt, Huber, Katharina T., Moulton, Vincent, Brochmann, Christian
Polyploidy, the duplication of entire genomes, plays a major role in plant evolution. In allopolyploids, genome duplication is associated with hybridization between two or more divergent genomes....
Reconstructing the Evolutionary History of Polyploids From Multi-labelled Trees (2006)
Huber, Katharina T., Oxelman, Bengt, Lott, Martin, Moulton, Vincent
In recent studies, phylogenetic networks have been derived from so-called multi-labelled trees in order to understand the origins of certain polyploids. Although the trees used in these studies were...
Reconstructing the Evolutionary History of Polyploids from Multilabeled Trees (2006)
Huber, Katharina T., Oxelman, Bengt, Lott, Martin, Moulton, Vincent
In recent studies, phylogenetic networks have been derived from so-called multilabeled trees in order to understand the origins of certain polyploids. Although the trees used in these studies were...
Svennblad, Bodil, Erixon, Per, Oxelman, Bengt, Britton, Tom
Using a four-taxon example under a simple model of evolution, we show that the methods of maximum likelihood and maximum posterior probability (which is a Bayesian method of inference) may not arrive...
Four low-copy nuclear DNA intron regions from the second largest subunits of the RNA polymerase gene family (RPA2, RPB2, RPD2a, and RPD2b), the internal transcribed spacers (ITSs) from the nuclear...
Reliability of Bayesian Posterior Probabilities and Bootstrap Frequencies in Phylogenetics (2003)
Erixon, Per, Svennblad, Bodil, Britton, Tom, Oxelman, Bengt
Many empirical studies have revealed considerable differences between nonparametric bootstrapping and Bayesian posterior probabilities in terms of the support values for branches, despite claimed...

Relationships of the enigmatic genera Whitfieldia, Chlamydacanthus, and Lankesteria (Acanthaceae) were examined using molecular sequence data for two chloroplast loci (ndhF gene, trnL-trnF spacer and...
Two APETALA2-like genes of Picea abies are differentially expressed during development (2001)
Vahala, Tiina, Oxelman, Bengt, Arnold, Sara Von
The EREBP/AP2 gene family codes for plant specific transcription factors. The first two gymnosperm genes of this family were isolated from Picea abies and shown to be structurally related, but...
Oxelman, Bengt, Bremer, Birgitta
Paralogous sequences of the RPB2 gene are demonstrated in the angiosperm order Gentianales. Two different copies were found by using different PCR primer pairs targeting a region that corresponds to...
Bremer, Birgitta, Jansen, Robert K., Oxelman, Bengt, Backlund, Maria, Lantz, Henrik, Kim, Ki-Joong
Using different data sets mainly from the plant family Rubiaceae, but in parts also from the Apocynaceae, Asteraceae, Lardizabalaceae, Saxifragaceae, and Solanaceae, we have investigated the effect...
