Evolution: New Gene-Rich Mitochondria Found Across the Eukaryotic Tree

Curr Biol. 2017 Dec 4;27(23):R1270-R1271. doi: 10.1016/j.cub.2017.10.028.


Mitochondria are the energy-generating organelles that power eukaryotic cells. Originally descended from endosymbiotic bacteria, their genomes have shrunk during evolution. New analyses suggest that large, gene-rich mitochondrial genomes are more common than previously thought, with interesting implications for eukaryotic genome evolution.
