摘要
Classically, sperm were seen as transcriptionally inactive vehicles for delivering the paternal haplotype to an egg. Yet, it has become apparent that sperm also carry thousands of different RNAs, and the functions of most of these are unknown. Here, we make four novel suggestions for sperm RNA function. First, they could act as relatedness markers facilitating sperm cooperation. Second, they could act as paternally imposed suppressors of haploid interests. Third, they could act as a nuptial gift, providing the female with resources that entice her to fertilise ova using the sperm of the gift-provider. Fourth, they could represent the contents of a Trojan horse, delivered by males to manipulate female reproduction. We discuss these ideas and suggest how they might be tested.

经典,精子被视为无转录活性的车辆提供父系单倍型,以一个鸡蛋。然而,它已经很明显,精子也携带数千种不同的RNA,以及大多数的这些功能是未知的。在这里,我们为精子RNA的功能四种新型建议。首先,它们可以作为相关性标志物促进精子合作。其次,他们可以作为父本强加的单倍体利益抑制器。第三,它们可以作为彩礼,提供与引诱她卵子受精用礼品提供的精子资源的女性。四,他们可以代表一个木马的内容,由男性传递到操纵雌性繁殖。我们讨论这些想法,并建议它们如何进行测试。
