Having a comprehensive understanding of population structure, genetic differentiation and demographic history is important for the conservation and management of threatened species. High‐throughput sequencing (HTS) provides exciting opportunities to address a wide range of factors for conservation genetics. Here, we generated HTS data and identified 266,884 high‐quality single nucleotide polymorphisms from 82 individuals of Cupressus chengiana, to assess population genomics across the species' full range, comprising the Daduhe River (DDH), Minjiang River (MJR) and Bailongjiang River (BLJ) catchments in western China. admixture , principal components analysis and phylogenetic analyses indicated that each region contains a distinct lineage, with high levels of differentiation between them (DDH, MJR and BLJ lineages). MJR was newly distinguished compared to previous surveys, and evidence including coalescent simulations supported a hybrid origin of MJR during the Quaternary. Each of these three lineages should be recognized as an evolutionarily significant unit (ESU), due to isolation, differing genetic adaptations and different demographic history. Currently, each ESU faces distinct threats, and will require different conservation strategies. Our work shows that population genomic approaches using HTS can reconstruct the complex evolutionary history of threatened species in mountainous regions, and hence inform conservation efforts, and contribute to the understanding of high biodiversity in mountains. 相似文献

[目的] 了解福州市公园的外来入侵植物种类组成,分析其原产地及入侵等级等情况,能够为福州外来入侵植物的扩散、防控以及生物多样性保护提供参考依据。[方法] 对福州市4个区49个公园的外来入侵植物种类、原产地、生活型、入侵频度、危害程度(入侵等级)等进行调查和分析。[结果] 在调查的福州市所有公园内均有入侵植物分布,目前有入侵植物66种,隶属25科,其中菊科、豆科、苋科3个科为优势科,共计33种(占50.00%);从来源上看,大多数原产于美洲,其次是非洲、欧洲、亚洲;以草本植物为主,共有55种(占83.30%);从入侵频度看,入侵频度超过50%的入侵植物有7种,其中小蓬草的频度最高,为87.76%;从入侵等级来看,其中恶性(1级)入侵植物16种,严重(2级)入侵植物14种,局部(3级)入侵植物12种,一般(4级)入侵植物11种,有待观察类(5级)13种。[结论] 当前福州市公园内的外来植物入侵现象比较严重,应当加强该区域的入侵植物监测与预警,防止入侵植物扩散从而造成重大生态危害。 相似文献

Histone deacetylase (HDAC) 10, a class II family, has been implicated in various tumors and non-tumor diseases, which makes the discovery of biological functions and novel inhibitors a fundamental endeavor. In cancers, HDAC10 plays crucial roles in regulating various cellular processes through its epigenetic functions or targeting some decisive molecular or signaling pathways. It also has potential clinical utility for targeting tumors and non-tumor diseases, such as renal cell carcinoma, prostate cancer, immunoglobulin A nephropathy (IgAN), intracerebral hemorrhage, human immunodeficiency virus (HIV) infection and schizophrenia. To date, relatively few studies have investigated HDAC10-specific inhibitors. Therefore, it is important to study the biological functions of HDAC10 for the future development of specific HDAC10 inhibitors. In this review, we analyzed the biological functions, mechanisms and inhibitors of HDAC10, which makes HDAC10 an appealing therapeutic target. 相似文献
