Phylogenetic relationships within Araucariaceae based on rbcL gene sequences

Phylogenetic relationships within Cornus (Cornaceae) based on 26S rDNA sequences.

Phylogenetic relationships within the dogwood genus Cornus have been highly controversial due to the great morphological heterogeneity. Earlier phylogenetic analyses of Cornus using chloroplast DNA (cpDNA) data (including rbcL and matK sequences, as well as restriction sites) and morphological characters suggested incongruent relationships within the genus. The present study generated sequence ...

Phylogenetic relationships within the Gentianales based on NDHF and RBCL sequences, with particular reference to the Loganiaceae.

Phylogenetic relationships in the Gentianales with focus on Loganiaceae sensu lato are evaluated using parsimony analyses of nucleotide sequence data from the plastid genes rbcL and ndhF. Inter- and intrafamilial relationships in the Gentianales, which consist of the families Apocynaceae (including Asclepiadaceae), Gelsemiaceae, Gentianaceae, Loganiaceae, and Rubiaceae, are studied and receive ...

Phylogenetic Analysis of the Zingiberales Based on rbcL Sequences

Phylogenetic Relationships of Extant Ferns Based on Evidence from Morphology and rbcL Sequences

-We present the first cladistic analysis of extant ferns based on morphological characters. Our data set consisted of 77 vegetative and reproductive morphological/anatomical characters recorded on a broad sampling of 50 extant pteridophyte taxa, with representatives of all major fern groups, and one seed plant (Cycas). An annotated list of both retained and excluded morphological characters is ...

A Comparison and Combination of Plastid atpB and rbcL Gene Sequences for Inferring Phylogenetic Relationships within Orchidaceae

Parsimony analyses of DNA sequences from the plastid genes atpB and rbcL were completed for 173 species of Orchidaceae (representing 150 different genera) and nine genera from outgroup families in Asparagales. The atpB tree topology is similar to the rbcL tree, although the atpB data contain less homoplasy and provide greater jackknife support than rbcL alone. In combination, the two-gene tree ...
