Author Information
Author(s): Karlberg et al.
Hypothesis
A free-living a-proteobacterium evolved into an endosymbiont of an anaerobic host, losing most of its ancestral bacterial genes.
Conclusion
The study suggests that the endosymbiont transformed into an ATP-exporting organelle by gaining genes from the nuclear genome.
Takeaway
Scientists think that a tiny bacteria became part of a bigger cell and changed to help make energy.
Methodology
Phylogenetic reconstructions involving over 400 yeast nuclear genes.
