Abstract

Abstract The population structure and genetic diversity of Rohu (Labeo rohita Hamilton, 1822) was studied by analysis of the partial sequences of mitochondrial DNA cytochrome b region. We examined 133 samples collected from six locations in three geographically isolated rivers of India. Analysis of 11 haplotypes showed low haplotype diversity (0.00150), nucleotide diversity (π) (0.02884) and low heterogeneity value (0.00374). Analysis of molecular variance (AMOVA) revealed the genetic diversity of L. rohita within population is very high than between the populations. The Fst scores (−0.07479 to 0.07022) were the indication of low genetic structure of L. rohita populations of three rivers of India. Conspicuously, Farakka-Bharuch population pair Fst score of 0.0000, although the sampling sites are from different rivers. The phylogenetic reconstruction of unique haplotypes revealed sharing of a single central haplotype (Hap_1) by all the six populations with a point mutations ranging from 1–25 nucleotides.

mtDNA细胞色素b区序列揭示了印度主要鲤鱼(Labeo rohita, Hamilton, 1822)的种群结构和遗传多样性

摘要通过线粒体DNA细胞色素b区部分序列分析，研究了罗虎(Labeo rohita Hamilton, 1822)的种群结构和遗传多样性。我们检查了从印度三条地理上孤立的河流的六个地点收集的133个样本。11个单倍型分析显示，单倍型多样性低(0.00150)，核苷酸多样性(π)低(0.02884)，异质性低(0.00374)。分子变异分析(AMOVA)表明，群体内的遗传多样性高于群体间的遗传多样性。Fst分数(- 0.07479 ~ 0.07022)表明印度三河地区罗氏菌居群遗传结构较低。值得注意的是，尽管采样点来自不同的河流，但Farakka-Bharuch种群对Fst得分为0.0000。单倍型的系统发育重建结果显示，6个群体的单倍型(Hap_1)具有相同的中心单倍型，点突变范围在1-25个核苷酸之间。

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.
