在许多真核生物物种中有性生殖的一个共同点是,卵子与过多的精子接触,以最大限度地提高生殖成功的机会。为了避免过多精子融合到单个雌性配子(多精)的潜在有害或有害后果,许多真核生物,包括植物,已经进化出了防止多精的屏障。通常,这些检查点在复制过程的不同阶段实现。事实上,关于开花植物中自然发生的卵细胞多精现象的明确报道的缺失,很可能反映了这种多相策略的成功,并突出了追踪这种可能罕见事件的难度。我们在此重点讨论植物中潜在的多精避免机制,并结合动物的类似过程进行讨论。
A common denominator of sexual reproduction in many eukaryotic species is the exposure of an egg to excess sperm to maximize the chances of reproductive success. To avoid potential harmful or deleterious consequences of supernumerary sperm fusion to a single female gamete (polyspermy), many eukaryotes, including plants, have evolved barriers preventing polyspermy. Typically, these checkpoints are implemented at different stages in the reproduction process. The virtual absence of unambiguous reports of naturally occurring egg cell polyspermy in flowering plants is likely reflecting the success of this multiphasic strategy and highlights the difficulty to trace this presumably rare event. We here focus on potential polyspermy avoidance mechanisms in plants and discuss them in light of analogous processes in animals.
