海洋棘鱼已经定居并适应了自上一个冰河时代以来形成的无数河流和湖泊，这为描述自然界重复生态适应的基因组机制提供了一个难得的机会。在这里，我们开发了一个高质量的参考基因组组装三刺鱼。通过对来自全球一组海洋和淡水种群的另外20个个体的基因组进行测序，我们确定了一组与海洋-淡水分歧一致相关的基因组范围内的位点。我们的研究结果表明，重用的全球共享的常设遗传变异，包括染色体倒位，在重复进化的不同的海洋和淡水刺鱼，并在维持不同的生态型在早期阶段的生殖隔离中发挥着重要作用。编码和调节变化都发生在海洋-淡水进化的基础基因座中，调节变化可能在自然界重复适应性进化的经典例子中占主导地位。
Marine stickleback fish have colonized and adapted to innumerable streams and lakes formed since the last ice age, providing an exceptional opportunity to characterize genomic mechanisms underlying repeated ecological adaptation in nature. Here we develop a high quality reference genome assembly for threespine sticklebacks. By sequencing the genomes of 20 additional individuals from a global set of marine and freshwater populations, we identify a genome-wide set of loci that are consistently associated with marine-freshwater divergence. Our results suggest that reuse of globally-shared standing genetic variation, including chromosomal inversions, plays an important role in repeated evolution of distinct marine and freshwater sticklebacks, and in the maintenance of divergent ecotypes during early stages of reproductive isolation. Both coding and regulatory changes occur in the set of loci underlying marine-freshwater evolution, with regulatory changes likely predominating in this classic example of repeated adaptive evolution in nature.
