Abstract

Host-parasite arms races facilitate rapid evolution and can fuel speciation. Cuculus cuckoos are deceptive egg mimics that exhibit a broad diversity of counterfeit egg phenotypes, representing host-adapted subpopulations (gentes). Genome analysis of 298 common (Cuculus canorus) and 50 oriental cuckoos (Cuculus optatus) spanning 15 egg morphs revealed that eggshell background coloration is predominantly influenced by matrilineal genetic variation. Recurrent mitochondrial mutations and an ancient W chromosome–linked translocation of an autosomal assembly factor for respiratory complex I provide a tentative link between mitochondrial function and pigment synthesis through the heme pathway. Biparentally inherited loci contribute to phenotypic variation in both species, mainly for maculation. The evolutionary tug-of-war over a sex-limited, mimetic trait integrates autosomal components with the nonrecombining, matrilineal genome without catalyzing genome-wide divergence between gentes.

卵模仿的基因组结构及其对寄生杜鹃物种形成的影响

宿主-寄生虫的军备竞赛促进了快速进化，并可以推动物种形成。杜鹃是一种具有欺骗性的卵仿制品，表现出广泛多样的假卵表型，代表了适应宿主的亚种群（基因）。对298只普通杜鹃（Cuculus canorus）和50只东方杜鹃（Cuculus optatus） 15种卵型的基因组分析表明，蛋壳背景颜色主要受母系遗传变异的影响。反复出现的线粒体突变和呼吸复合体I常染色体组装因子的古老W染色体相关易位提供了线粒体功能与通过血红素途径合成色素之间的初步联系。双亲本遗传位点导致了两种物种的表型变异，主要表现为斑疹。性别限制的进化拉锯战，模仿性状整合常染色体成分与非重组，母系基因组，没有催化基因之间的全基因组分化。

期刊介绍： Science is a leading outlet for scientific news, commentary, and cutting-edge research. Through its print and online incarnations, Science reaches an estimated worldwide readership of more than one million. Science’s authorship is global too, and its articles consistently rank among the world's most cited research. Science serves as a forum for discussion of important issues related to the advancement of science by publishing material on which a consensus has been reached as well as including the presentation of minority or conflicting points of view. Accordingly, all articles published in Science—including editorials, news and comment, and book reviews—are signed and reflect the individual views of the authors and not official points of view adopted by AAAS or the institutions with which the authors are affiliated. Science seeks to publish those papers that are most influential in their fields or across fields and that will significantly advance scientific understanding. Selected papers should present novel and broadly important data, syntheses, or concepts. They should merit recognition by the wider scientific community and general public provided by publication in Science, beyond that provided by specialty journals. Science welcomes submissions from all fields of science and from any source. The editors are committed to the prompt evaluation and publication of submitted papers while upholding high standards that support reproducibility of published research. Science is published weekly; selected papers are published online ahead of print.
