Abstract

Background

The domesticated pigeon (Columba livia domestica) possesses many valuable traits including high nutritional value and fast growth. However, there is a paucity of information on the genetic diversity and population structure of Nigerian domestic pigeon populations.

Methods and results

We examined the pattern of the genetic variability using three concatenated sequences from cytochrome oxidase subunit I (COI), cytochrome B (CYTB), and D-loop. We studied 150 captured pigeons from three agro-ecological zones in Nigeria. The result showed 52 haplotypes (HT1-HT52) occurred only in Nigerian populations based on the three concatenated sequences. The overall haplotype diversity was 0.876 ± 0.019, and nucleotide diversity 0.055 ± 0.027. The phylogenetic tree showed significant clustering and genetic relationship of Nigerian domestic pigeons. The median-joining network showed two groups (A and B) in the Nigerian pigeon population. The group A exhibits historical population expansion which are supported by neutrality test results and Bayesian skyline plot (BSP) for the 146 Nigerian pigeon populations.

Conclusions

This study revealed unique haplotypes, low genetic diversity, and population differentiation of Nigerian domestic pigeons.

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.
