Abstract

Nigerian laughing doves (Streptopelia senegalensis) are small birds with long tail and living in bushes of the Sub-Saharan regions of African continent, the middle East and Asia, especially India. They are used for food, medicinal and religious purposes in Nigeria. Despite their usage, there is a lack of information on the genetic diversity of laughing doves in Nigeria. This study investigates taxonomic order and diversity of Nigerian laughing doves based on the mitochondrial cytochrome oxidase subunit I (COI) and cytochrome B (CYTB). The results showed 20 haplotypes within the 28 Nigerian coupled with Global Streptopelia genus using concatenated sequences. The Nigerian laughing dove constitute 16 distinct haplotypes. The haplotype diversity was 0.743 ± 0.070, and nucleotide diversity 0.154 ± 0.101 within Nigerian population using COI sequences. Phylogenetic tree showed that Nigerian laughing doves were in the same monophyletic clade with other Streptopela orientalis, S. decocto and S. chinensis; and this confirmed that Nigerian laughing doves might have shared descendant. The median-joining network further grouped Nigerian laughing doves into two: the first group consisting of Nigerian populations only, while the second group are with Saudi Arabian and Djiboutian populations. Population expansion was revealed in Nigerian dove individuals. This study revealed 16 unique haplotypes among Nigerian laughing dove population using concatenated sequences. Interestingly, CYTB showed clustering in African laughing doves (For instance, Nigerian individuals shared haplotypes with Sao Tome and Principe, an island country in the Gulf of Guinea, the western equatorial coast of Central Africa). The current data is the first report on genetic diversity of Nigerian laughing dove using mitochondrial COI and CYTB genes.

利用选定的线粒体基因对尼日利亚笑鸽（Streptopelia senegalensis）及相关物种进行分子遗传多样性分析

尼日利亚笑鸽（Streptopelia senegalensis）是一种长尾小鸟，生活在非洲大陆撒哈拉以南地区、中东和亚洲（尤其是印度）的灌木丛中。在尼日利亚，它们被用作食物、药用和宗教用途。尽管笑鸽有多种用途，但有关尼日利亚笑鸽遗传多样性的信息却很缺乏。本研究根据线粒体细胞色素氧化酶亚单位 I（COI）和细胞色素 B（CYTB）对尼日利亚笑鸽的分类顺序和多样性进行了调查。研究结果表明，使用连接序列，28 个尼日利亚笑鸽属（Nigerian coupled with Global Streptopelia genus）中有 20 个单倍型。尼日利亚笑鸽构成了 16 个不同的单倍型。使用 COI 序列，尼日利亚种群的单倍型多样性为 0.743 ± 0.070，核苷酸多样性为 0.154 ± 0.101。系统发生树显示，尼日利亚笑鸽同其他东方链鸽（Streptopela orientalis）、S. decocto和S. chinensis同属一个单系支系，这证实尼日利亚笑鸽可能有共同的后代。中位连接网络进一步将尼日利亚笑鸽群分为两组：第一组仅包括尼日利亚种群，而第二组则包括沙特阿拉伯和吉布提种群。尼日利亚笑鸽个体的种群扩张得到了揭示。这项研究利用连接序列在尼日利亚笑鸽种群中发现了 16 种独特的单倍型。有趣的是，CYTB 在非洲笑鸽群中显示出聚类现象（例如，尼日利亚个体与圣多美和普林西比个体共享单倍型，圣多美和普林西比是几内亚湾的一个岛国，位于中非赤道西岸）。目前的数据是首次利用线粒体 COI 和 CYTB 基因研究尼日利亚笑鸽遗传多样性的报告。

期刊介绍： Gene Reports publishes papers that focus on the regulation, expression, function and evolution of genes in all biological contexts, including all prokaryotic and eukaryotic organisms, as well as viruses. Gene Reports strives to be a very diverse journal and topics in all fields will be considered for publication. Although not limited to the following, some general topics include: DNA Organization, Replication & Evolution -Focus on genomic DNA (chromosomal organization, comparative genomics, DNA replication, DNA repair, mobile DNA, mitochondrial DNA, chloroplast DNA). Expression & Function - Focus on functional RNAs (microRNAs, tRNAs, rRNAs, mRNA splicing, alternative polyadenylation) Regulation - Focus on processes that mediate gene-read out (epigenetics, chromatin, histone code, transcription, translation, protein degradation). Cell Signaling - Focus on mechanisms that control information flow into the nucleus to control gene expression (kinase and phosphatase pathways controlled by extra-cellular ligands, Wnt, Notch, TGFbeta/BMPs, FGFs, IGFs etc.) Profiling of gene expression and genetic variation - Focus on high throughput approaches (e.g., DeepSeq, ChIP-Seq, Affymetrix microarrays, proteomics) that define gene regulatory circuitry, molecular pathways and protein/protein networks. Genetics - Focus on development in model organisms (e.g., mouse, frog, fruit fly, worm), human genetic variation, population genetics, as well as agricultural and veterinary genetics. Molecular Pathology & Regenerative Medicine - Focus on the deregulation of molecular processes in human diseases and mechanisms supporting regeneration of tissues through pluripotent or multipotent stem cells.
