Kajander等人的一篇新论文推翻了线粒体不会重组的普遍观点。作者发现了“升华”的存在,重排的线粒体基因组在健康的人类患者中以非常低的水平存在。重要的是,不同的重排线粒体基因组理论上可以通过线粒体内重组相互转换。线粒体内重组的假定操作应该会影响我们对线粒体基因如何进化的想法,特别是关于线粒体基因组如何重排的想法。
A new paper by Kajander et al. undermines the general view that mitochondria do not recombine. The authors discovered the existence of 'sublimons', rearranged mitochondrial genomes present at very low levels in healthy human patients. Crucially, the different rearranged mitochondrial genomes can theoretically be interconverted through intramitochondrial recombination. The putative operation of intramitochondrial recombination should impact on our ideas of how mitochondrial genes evolve, particularly with respect to how mitochondrial genomes rearrange.
