Plant Mitochondrial Genome Evolution and Cytoplasmic Male Sterility

Mitochondria are responsible for providing energy currency to life processes in the molecular form of ATP and are therefore typically referred to as the power factories of cells. Plant mitochondria are also relevant to the common phenomenon of cytoplasmic male sterility, which is agronomically important in various crop species. Cytoplasmic male sterility (CMS) is a complex trait that may be influenced by patterns of mitochondrial genome evolution, and by intergenomic gene transfer among the organellar and nuclear compartments of plant cells. Here, we review patterns and processes that shape plant mitochondrial genomes, some relevant interactions between organelles, and the general features shared by the majority of cytoplasmic male-sterile genes in plants to further the goal of understanding CMS.

线粒体会以ATP的形式向整个生命过程提供“能量货币”，因此被称为细胞的“能量工厂”。植物线粒体还会与细胞质雄性不育的现象相关，而该性状是多种作物中非常重要的农艺性状。细胞质雄性不育，简称CMS，是一个复杂的性状，其可能受到线粒体基因组进化的影响，同样还受到植物细胞的细胞器和核基因组之间的基因转移的影响。本文对改变植物线粒体基因组的模式和进程进行了综述，以及一些细胞器之间的相互作用、大多数植物细胞质雄性不育相关基因的一般特征，以期能够帮助我们进一步深入理解CMS。
