Phylogeny and disjunct distribution: evolution of Saintpaulia (Gesneriaceae)

A Cladistic Analysis of ndhF Sequences from Representative Species of Saintpaulia and Streptocarpus Subgenera and Streptocarpella (Gesneriaceae)

Bacterial and eukaryotic phosphoketolases: phylogeny, distribution and evolution.

Phosphoketolases (XFPs) are glycolytic enzymes present in several organisms belonging to the Eukarya and Bacteria domains. A total of 151 putative xfp genes were detected in 650 complete genomes available in public databases. Elimination of redundant sequences and pseudogenes rendered a final data set of 128 phosphoketolases, which was analyzed by phylogenetic methods. The distribution of xfp g...

Phylogeny and Evolution of Dendrites

Dendrites, the neuronal processes that receive synaptic inputs, are found in all nervous systems. The great diversity of dendrites, both within individual species and across phylogeny, reflects their adaptation to particular functional roles. In the present article we use this diversity to consider dendrites from an evolutionary perspective. We first describe some principles seen in the diversi...

Mathematics of Evolution and Phylogeny

Gene-order data have been used successfully to reconstruct organellar phylogenies; they offer low error rates, the potential to reach farther back in time than through DNA sequences (because genome-level events are rarer than DNA point mutations), and immunity from the so-called gene-tree vs. species-tree problem (caused by the fact that the evolutionary history of specific genes is not isomorp...
