这是首次对野生窄叶羽扇豆的遗传多样性进行泛地中海分析，揭示了种群的东西方遗传分化、历史性的东向迁移以及遗传适应气候变量的特征。大多数粮食作物的遗传基础狭窄，这限制了它们适应新挑战的潜力，例如与气候变化相关的压力增加。植物育种者正在回归作物的野生祖先及其近亲，以扩大作物的遗传基础。了解这些野生亲缘植物的遗传适应性将有助于植物育种者最有效地利用现有的野生多样性。本文以窄叶羽扇豆（Lupinus angustifolius L.）作为理解野生作物祖先适应性的模型。一组142个野生品种的窄叶羽扇豆从整个地中海盆地进行基因分型测序使用多样性阵列技术。系统发育，连锁不平衡和人口统计学分析，探讨了地中海地区的窄叶羽扇豆的历史。我们发现强大的遗传分化之间的加入从西部和东部的地中海，一个历史性的西向东迁移的证据，和地中海东部窄叶羽扇豆经历了一个严重的和最近的遗传瓶颈。我们发现，这两个群体不同的开花时间作为当地适应的结果，与西方开花晚，而东方开花早。一项全基因组关联研究确定了与气候适应相关的单核苷酸多态性标记。解决野生窄叶羽扇豆的起源及其迁移如何引起地中海特定地区的适应，不仅是开发对气候变化具有更大适应力的窄叶羽扇豆品种的有用资源，而且也是可应用于其他豆类的模式。本文的在线版本（10.1007/s 00122 -017-3045-7）包含补充材料，可供授权用户使用。
This first pan-Mediterranean analysis of genetic diversity in wild narrow-leafed lupin revealed strong East–West genetic differentiation of populations, an historic eastward migration, and signatures of genetic adaptation to climatic variables. Most grain crops suffer from a narrow genetic base, which limits their potential for adapting to new challenges such as increased stresses associated with climate change. Plant breeders are returning to the wild ancestors of crops and their close relatives to broaden the genetic base of their crops. Understanding the genetic adaptation of these wild relatives will help plant breeders most effectively use available wild diversity. Here, we took narrow-leafed lupin (Lupinus angustifolius L.) as a model to understand adaptation in a wild crop ancestor. A set of 142 wild accessions of narrow-leafed lupin from across the Mediterranean basin were subjected to genotyping-by-sequencing using Diversity Arrays Technology. Phylogenetic, linkage disequilibrium and demographic analyses were employed to explore the history of narrow-leafed lupin within the Mediterranean region. We found strong genetic differentiation between accessions from the western and eastern Mediterranean, evidence of an historic West to East migration, and that eastern Mediterranean narrow-leafed lupin experienced a severe and recent genetic bottleneck. We showed that these two populations differ for flowering time as a result of local adaptation, with the West flowering late while the East flowers early. A genome-wide association study identified single nucleotide polymorphism markers associated with climatic adaptation. Resolving the origin of wild narrow-leafed lupin and how its migration has induced adaptation to specific regions of the Mediterranean serves as a useful resource not only for developing narrow-leafed lupin cultivars with greater resilience to a changing climate, but also as a model which can be applied to other legumes.
