Analysis of the Amborella trichopoda chloroplast genome sequence suggests that amborella is not a basal angiosperm.
The majority of phylogenetic analyses of protein-coding genes of this chloroplast DNA suggests that Amborella is not the basal angiosperm and not even the most basal among dicots. Expand
Analysis of Acorus calamus chloroplast genome and its phylogenetic implications.
It is shown that the tree recovered under ML is extremely sensitive to model specification and that the best symmetric model is misspecified, and remains agnostic regarding phylogenetic relationships among basal angiosperm lineages. Expand

  • 31 July 2003
The myrmekochory syndrome, adaptation to man-made habitats, chromosome and genome evolution, and modes of reproduction receive special attention, reflected by morphology as well as DNA sequences. Expand
The chloroplast genome of the “basal” angiosperm Calycanthus fertilis – structural and phylogenetic analyses
Phylogenetic analysis of the protein-coding subset of the plastome suggests that the ancient line of Laurales emerged after the split of the angiosperms into monocots and dicots. Expand
Genetic diversity of Ranunculus acris L. (Ranunculaceae) populations in relation to species diversity and habitat type in grassland communities
It is found that habitat characteristics influence the genetic diversity of plant species, and populations of R. acris from the ‘seminatural’ habitat were genetically different from those in ‘agriculturally improved’ habitats, suggesting that gene flow between these habitat types is limited. Expand
The chloroplast genome of Nymphaea alba: whole-genome analyses and the problem of identifying the most basal angiosperm.
Phylogenetic analyses of the chloroplast DNA of Nymphaea alba revealed consistent support for Nympholia being a divergent member of a monophyletic dicot assemblage and observations suggesting that the monocot lineage leading to the grasses has the strongest phylogenetic affinity to gymnosperms have general implications for studies of substitution model specification and analyses of concatenated genome data.

A phylogenetic analysis of Primulaceae s.l. based on internal transcribed spacer (ITS) DNA sequence data
The phylogenetic reconstructions based on plastid gene sequences found the Primulaceae family to be paraphyletic and resolved the positions of some genera, but there is evidence against the monophyly of the large genera Primula, Androsace, and Lysimachia. Expand
Phylogenetic relationships in Carex, subgenus Vignea (Cyperaceae), based on ITS sequences
Abstract.To evaluate the sectional classification in Carex, subgenus Vignea, the ITS region of 58 species of 20 sections was analyzed with Neighbor Joining (NJ) and Markov chain Monte Carlo (MCMC)Expand
Further support for the phylogenetic relationships within Euphorbia L. (Euphorbiaceae) from nrITS and trnL–trnF IGS sequence data
The hypothesis that Euphorbia evolved in Africa from progenitors of subgen. Expand
The molecular phylogeny of Rebutia (Cactaceae) and its allies demonstrates the influence of paleogeography on the evolution of South American mountain cacti.
It is found that the clade of cephalia-bearing cacti with naked pericarpels is centered in northeastern Brazil, whereas almost all other clades comprise Andean species, and the phylogenetic reconstructions based on parsimony and Bayesian approaches do not reflect the traditional delimitation of the tribes and of the large genera.
