Abstract

Abstract Assessment of genetic diversity within and between populations is a prerequisite for sustainable utilization of domestic species. The domestic Muscovy duck (Cairina moschata) is an economically important species around the world for its unique meat taste and low-caloric content. It is one of the important domestic species in India as it ensures food security to the rural sectors. In this study, we have analyzed the genetic diversity and relationship of four Muscovy duck populations collected from different states (Assam, Mizoram, Odisha and Kerala) of India using mtDNA cytochrome b and nuclear DNA CYP2U1 genes. The results showed low genetic diversity among populations for both the genes. Kerala population showed significant genetic differences from the other three populations. The median joining network of cytochrome b gene suggested that the domestic Muscovy ducks present in India are the product of a single domestication event and probably introduced to India several years ago, as reported elsewhere. This study has also showed the suitability of nuclear DNA CYP2U1 gene in genetic diversity analysis.

印度番鸭种群的遗传多样性及亲缘关系

种群内和种群间遗传多样性的评估是国内物种可持续利用的先决条件。国内番鸭(Cairina moschata)因其独特的肉味和低热量含量而成为世界上重要的经济物种。它是印度重要的国内物种之一，因为它确保了农村部门的粮食安全。本研究利用mtDNA细胞色素b和核DNA CYP2U1基因分析了来自印度不同邦(阿萨姆邦、米佐拉姆邦、奥里萨邦和喀拉拉邦)的4个麝鸭种群的遗传多样性和亲缘关系。结果表明，这两个基因在群体间的遗传多样性较低。喀拉拉邦群体与其他三个群体存在显著的遗传差异。细胞色素b基因的中间连接网络表明，印度的家番鸭是单一驯化事件的产物，可能在几年前被引入印度，正如其他地方报道的那样。本研究还证实了核DNA CYP2U1基因在遗传多样性分析中的适用性。

期刊介绍： Mitochondrial DNA Part A publishes original high-quality manuscripts on physical, chemical, and biochemical aspects of mtDNA and proteins involved in mtDNA metabolism, and/or interactions. Manuscripts on cytosolic and extracellular mtDNA, and on dysfunction caused by alterations in mtDNA integrity as well as methodological papers detailing novel approaches for mtDNA manipulation in vitro and in vivo are welcome. Descriptive papers on DNA sequences from mitochondrial genomes, and also analytical papers in the areas of population genetics, phylogenetics and human evolution that use mitochondrial DNA as a source of evidence for studies will be considered for publication. The Journal also considers manuscripts that examine population genetic and systematic theory that specifically address the use of mitochondrial DNA sequences, as well as papers that discuss the utility of mitochondrial DNA information in medical studies and in human evolutionary biology.
