摘要

所有真核生物都可以追溯到一个共同的祖先,它是由不同原核细胞之间的相互作用产生的。目前的真核生成模型描述了真核细胞形成的各种选择性力量和进化机制。在这一过程中,细胞结构发生了重大变化,从而形成了一种以内部膜分区为特征的新细胞类型。此外,真核生物的生命周期依赖于细胞-细胞融合。我们讨论了参与重塑细胞膜的蛋白质的潜在作用,强调了真核生物进化过程中的两个关键阶段:共生伙伴的内化,以及有性生殖的出现与细胞融合产生的多倍体祖先有关。

Membrane fusion and fission during eukaryogenesis

All eukaryotes can be traced back to a single shared ancestral lineage that emerged from interactions between different prokaryotic cells. Current models of eukaryogenesis describe various selective forces and evolutionary mechanisms that contributed to the formation of eukaryotic cells. Central to this process were significant changes in cellular structure, resulting in the configuration of a new cell type characterized by internal membrane compartments. Additionally, eukaryogenesis results in a life cycle that relies on cell–cell fusion. We discuss the potential roles of proteins involved in remodeling cellular membranes, highlighting two critical stages in the evolution of eukaryotes: the internalization of symbiotic partners and a scenario wherein the emergence of sexual reproduction is linked to a polyploid ancestor generated by cell–cell fusion.
