Abstract
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.
摘要
线粒体是为真核细胞提供能量的细胞器。它们最初起源于内共生细菌，在进化过程中其基因组缩小了。新的分析表明，含有大量基因的大型线粒体基因组比以前认为的更为常见，这对真核生物基因组的进化具有有趣的启示。
