Supertrees and symbiosis in eukaryote genome evolution.
If we took all of the single copy genes in all sequenced genomes, made phylogenetic trees from them individually, and then made the supertree of those trees, what would we get? Recently, David Pisani and colleagues did that experiment and their results are likely to spark much discussion. Their prokaryote tree looks very familiar, but the genome history of eukaryotes appears dominated by genes ...
متن کاملMembranes, energetics, and evolution across the prokaryote-eukaryote divide
The evolution of the eukaryotic cell marked a profound moment in Earth's history, with most of the visible biota coming to rely on intracellular membrane-bound organelles. It has been suggested that this evolutionary transition was critically dependent on the movement of ATP synthesis from the cell surface to mitochondrial membranes and the resultant boost to the energetic capacity of eukaryoti...
متن کاملEvolution: Revisiting the Root of the Eukaryote Tree
A recent phylogenomic investigation shows that the enigmatic flagellate Breviata is a distinct anaerobic lineage within the eukaryote super-group Amoebozoa and challenges the unikont-bikont rooting of the tree of eukaryotes.
متن کاملNovel role of calmodulin in regulating protein transport to mitochondria in a unicellular eukaryote.
Lower eukaryotes like the kinetoplastid parasites are good models to study evolution of cellular pathways during steps to eukaryogenesis. In this study, a kinetoplastid parasite, Leishmania donovani, was used to understand the process of mitochondrial translocation of a nucleus-encoded mitochondrial protein, the mitochondrial tryparedoxin peroxidase (mTXNPx). We report the presence of an N-term...
متن کاملThe early adaptive evolution of calmodulin.
Interaction between gene duplication and natural selection in molecular evolution was investigated utilizing a phylogenetic tree constructed by the parsimony procedure from amino acid sequences of 50 calmodulin-family protein members. The 50 sequences, belonging to seven protein lineages related by gene duplication (calmodulin itself, troponin-C, alkali and regulatory light chains of myosin, pa...
