The Cape Verde palm tree, , holds significant ecological and cultural importance within the Cape Verde archipelago. However, its genetic distinctiveness has been questioned due to its close relationship and morphological similarity to the date palm (). In this study, we used an expanded sample set, 18 simple sequence repeat (SSR) markers, and a plastid minisatellite to characterize in Cape Verde and investigate its relationship with other species. Our findings identify genetic markers that differentiate the genetic pool, including a unique fixed allele. We also provide evidence of the recent divergence of from Northern African date palm populations, suggesting a relatively recent colonization of Cape Verde by palm trees. Additionally, we characterized the genetic composition of palm tree populations across three Cape Verde islands, concluding that wild samples from certain populations in Boavista and Sal are best suited for establishing a seed and/or germplasm bank for replantation efforts, representing a crucial step for the conservation of Cape Verde's natural heritage. Overall, our results enhance the understanding of the historical trajectories and genetic characterization of palm trees in Africa, offering valuable insights for conservation strategies.
佛得角棕榈树在佛得角群岛具有重要的生态和文化意义。然而，由于它与海枣关系密切且形态相似，其遗传独特性受到了质疑。在本研究中，我们使用了一个扩大的样本集、18个简单序列重复（SSR）标记和一个质体微卫星来对佛得角的该棕榈树进行特征描述，并研究它与其他棕榈树物种的关系。我们的研究结果确定了区分该棕榈树基因库的遗传标记，包括一个独特的固定等位基因。我们还提供了该棕榈树与北非海枣种群近期分化的证据，表明棕榈树相对较新才在佛得角定居。此外，我们描述了佛得角三个岛屿上棕榈树种群的遗传组成，得出结论认为，来自博阿维斯塔岛和萨尔岛某些种群的野生样本最适合建立种子和/或种质库用于重新种植工作，这是保护佛得角自然遗产的关键一步。总体而言，我们的结果增进了对非洲棕榈树历史轨迹和遗传特征的理解，为保护策略提供了宝贵的见解。
