Evolutionary biology: The hydrogenosome's murky past
Michael W. Gray1
Abstract
The evolution of specialized cellular powerhouses called hydrogenosomes has long confounded biologists. The discovery that in some cases they have their own genome sheds some much-needed light on the issue.
Hydrogenosomes are double-membraned subcellular structures that generate hydrogen while making the energy-storage compound ATP. They are found in certain eukaryotic (nucleus-containing) microbes that inhabit oxygen-deficient environments1.
