项目摘要
We respond to our environments in all sorts of ways, generally to fit in or become more competitive - such responses are usually beneficial, though can also be expressed in a pathological manner as so-called 'gang' or 'lad' culture. As an example of a social / sexual response, we may often adopt the speech patterns or mannerisms of the people we are talking to in an unknowing effort to ease communication. The animal world is full of analogous examples. Males in groups perceive that they are under a potentially elevated risk of competition for mates and matings. Hence such males may compete more strongly for matings, elevate their courtship rituals, mate for longer and transfer more sperm and ejaculate proteins when they do mate. These effects have been shown to benefit males that are subject to reproductive competition by allowing them to increase their investment in reproduction when it is relevant to do so.Our work shows that females also show substantial variation in responses to males, mating and sexual context. However, virtually nothing is yet known about the significance of these responses. Unlike for males, we do not know the benefits of responding to the sexual environment, nor what the consequences are for the female's offspring. This is especially important as parental social experience can influence offspring performance through non-genetic effects. Hence mothers may be able to 'prepare' their offspring for the prevailing competitive environment.Hence, we conclude that both sexes can express considerable plasticity in responses to the environment, which offers much raw material upon which natural selection can act. Yet the significance of all this genetic variation remains a mystery.In addition, given that both sexes can exhibit reproductive plasticity (e.g. in how much investment to make in each reproductive episode) it is surprising that we don't yet know what the sum contribution of these effects is to an individual's overall reproductive success. When both mating partners are in agreement with one another over reproductive decisions, then '2 partner plasticity' should increase overall reproductive success. However, if there is conflict, as there often is, then the benefits of plasticity expressed by each partner may cancel each other out.All these ideas have never previously been tested.We propose here a highly novel research programme to tackle big gaps in our understanding of sexual plasticity in females. We will use fully genome-sequenced 'iso-female' lines. These offer the potential to measure the extent of genetic variation in each of the experiments we will conduct and, in the future, to pin down the genome regions associated with each reproductive character in much the same way as tests of genes 'for' specific diseases are conducted by medical researchers. We have 3 broad aims:1. To measure the benefits for females of expressing reproductive plasticity.2. To discover whether females can signal the likely competitive environment into which their male and female offspring will emerge.3. To discover how the plastic responses of male and females interact. The results will contribute significantly to our fundamental understanding of reproductive decisions made by males and females. They will also reveal the mechanisms by which females can sense competition and signal competitiveness to future generations.
我们以各种方式对我们的环境做出反应,通常是为了适应或变得更具竞争力-这种反应通常是有益的,尽管也可以以一种病态的方式表达为所谓的“帮派”或“小伙子”文化。作为社会/性反应的一个例子,我们可能经常在不知不觉中采用与我们交谈的人的言语模式或习惯,以便于沟通。动物世界充满了类似的例子。群体中的男性认为,他们是在一个潜在的竞争和交配的风险升高。因此,这样的雄性可能会更强烈地竞争交配,提高他们的求偶仪式,交配时间更长,并在交配时转移更多的精子和射精蛋白。这些影响已被证明是有益的男性生殖竞争,让他们增加他们的投资在生殖时,它是相关的这样做。我们的工作表明,女性也表现出很大的变化,在响应男性,交配和性环境。然而,实际上还不知道这些反应的意义。与雄性不同,我们不知道对性环境做出反应的好处,也不知道对雌性后代的后果。这一点尤其重要,因为父母的社会经验可以通过非遗传效应影响后代的表现。因此,母亲可能能够“准备”他们的后代占主导地位的竞争环境。因此,我们得出结论,两性都可以表现出相当大的可塑性,在对环境的反应,这提供了许多原料,自然选择可以采取行动。然而,所有这些遗传变异的意义仍然是一个谜。此外,考虑到两性都可以表现出生殖可塑性(例如,在每次生殖过程中投入多少),令人惊讶的是,我们还不知道这些影响对个体整体生殖成功的贡献。当两个交配伙伴在生殖决定上彼此一致时,那么“2个伴侣的可塑性”应该会增加整体的生殖成功率。然而,如果有冲突,就像经常发生的那样,那么每个伴侣所表达的可塑性的好处可能会相互抵消。所有这些想法以前都没有得到过验证。我们在这里提出了一个非常新颖的研究计划,以解决我们对女性性可塑性理解的巨大差距。我们将使用完全基因组测序的“等雌性”系。这些技术提供了在我们将要进行的每一项实验中测量遗传变异程度的可能性,并且在未来,以与医学研究人员进行特定疾病基因测试相同的方式确定与每个生殖特征相关的基因组区域。我们有三大目标:1。测量表达生殖可塑性对女性的益处.发现雌性是否能发出信号,表明它们的雄性和雌性后代将出现在可能的竞争环境中。去发现男性和女性的可塑性反应是如何相互作用的。这些结果将有助于我们对男性和女性生殖决定的基本理解。它们还将揭示女性感知竞争并向后代发出竞争信号的机制。
