The vast majority of mitochondrial proteins are in all eukaryotes encoded in the nuclear genomes by genes which have been transferred from the original endosymbiont. DNA as well as RNA was and is exchanged between organelles. A functionally successful information transfer, however, requires complex structural and regulatory alterations of the concerned gene. The recently identified variations of the information content in mitochondrial genomes of different plant species represent different stages of the transfer process. These evolutionary intermediates allow a definition of requirements and chances of successful gene transfers.
在所有真核生物中，绝大多数线粒体蛋白质是由从原始内共生体转移而来的基因在核基因组中编码的。细胞器之间过去和现在都存在DNA以及RNA的交换。然而，功能上成功的信息传递需要相关基因进行复杂的结构和调控改变。最近在不同植物物种线粒体基因组中发现的信息含量变化代表了转移过程的不同阶段。这些进化中间体有助于明确成功基因转移的要求和可能性。
