Due to the endosymbiotic origin of organelles, a pattern of coevolution and coadaptation between organellar and nuclear genomes is required for proper cell function. In this review, we focus on the impact of cytonuclear interaction on the reproductive isolation of plant species. We give examples of cases where species exhibit barriers to reproduction which involve plastid-nuclear or mito-nuclear genetic incompatibilities, and describe the evolutionary processes at play. We also discuss potential mechanisms of hybrid fitness recovery such as paternal leakage. Finally, we point out the possible interplay between plant mating systems and cytonuclear coevolution, and its consequence on plant speciation.
由于细胞器的内共生起源，细胞器基因组与核基因组之间的共同进化和共同适应模式是细胞正常功能所必需的。在这篇综述中，我们重点关注细胞核与细胞质相互作用对植物物种生殖隔离的影响。我们给出了一些物种表现出繁殖障碍的例子，这些障碍涉及质体-核或线粒体-核遗传不相容性，并描述了其中起作用的进化过程。我们还讨论了杂种适应性恢复的潜在机制，如父本渗漏。最后，我们指出了植物交配系统与细胞核-细胞质共同进化之间可能的相互作用及其对植物物种形成的影响。
