两性之间的相互作用被认为是性别特异性进化选择的有力来源。人们对性互动影响男性投资的方式进行了大量研究，但对女性的影响却知之甚少。为了解决这一缺陷，我们在100代的交配系统操作中检测了雌性果蝇的基因表达，在交配系统操作中，我们要么提高多夫制，要么强制一妻制。交配系统操纵后的基因表达进化导致14%的处女雌性转录组被改变。一妻多夫制的雌性提高了卵巢中通常富集的基因的表达，这些基因与有丝分裂和减数分裂有关，这可能反映了雌性对生殖功能的投入。单雄性雌性显示出更多通常在体细胞组织中表达的基因，包括头部和肠道，分别与视觉感知和代谢相关。通过将我们的数据与先前对该物种基因表达性别差异的研究进行比较，我们发现大多数在选择处理的雌性之间差异表达的基因在野生型群体中表现出雌性偏向性表达。一个显著的例外是与雄性特异性生殖组织相关的基因（在黑腹龙中），在一夫多妻制的雌性中上调。我们的研究结果为性别特异性选择在促进雌性转录组快速进化中的作用提供了实验证据。
Interactions between the sexes are believed to be a potent source of selection on sex-specific evolution. The way in which sexual interactions influence male investment is much studied, but effects on females are more poorly understood. To address this deficiency, we examined gene expression in virgin female Drosophila pseudoobscura following 100 generations of mating system manipulations in which we either elevated polyandry or enforced monandry. Gene expression evolution following mating system manipulation resulted in 14% of the transcriptome of virgin females being altered. Polyandrous females elevated expression of a greater number of genes normally enriched in ovaries and associated with mitosis and meiosis, which might reflect female investment into reproductive functions. Monandrous females showed a greater number of genes normally enriched for expression in somatic tissues, including the head and gut and associated with visual perception and metabolism, respectively. By comparing our data with a previous study of sex differences in gene expression in this species, we found that the majority of the genes that are differentially expressed between females of the selection treatments show female-biased expression in the wild-type population. A striking exception is genes associated with male-specific reproductive tissues (in D. melanogaster), which are upregulated in polyandrous females. Our results provide experimental evidence for a role of sex-specific selection arising from differing sexual interactions with males in promoting rapid evolution of the female transcriptome.
