The maternally inherited mitochondrial DNA (mtDNA) D–loop region is widely used for exploring genetic relationships and for investigating the origin of various animal species. Currently, domestic duck...
The aim of our study was to determine the prevalence of hepatitis E virus (HEV) in domestic pigs and to investigate the genetic divergence of swine HEV in the Czech Republic. To this end, a one-step r...
Canine parvovirus 2 (CPV-2) is the causative agent of acute hemorrhagic enteritis and myocarditis in dogs. In this study the nucleotide sequence of the VP1/VP2 gene of a CPV isolate from India was ana...
Armored scale insects (Hemiptera: Diaspididae) are among the most invasive insects in the world. They have unusual genetic systems, including diverse types of paternal genome elimination (PGE) and par...
The use of Korean native chicken is increasing, and the discovery of new genetic resources is very important from both economic and genetic conservation points of view. In this study, mtDNA D-loop seq...
In this paper, I study the application of phylogenetic analysis in evolutionary archaeology. I show how transfer of this apparently general analytic tool is affected by salient differences in discipli...
摘要 测定了双壳纲不同科、属、种及种内共11个个体的核糖体RNA 18S-ITS1序列。结果表明,该序列在种间存在很高的多态性,长度从558 bp到784 bp不等,碱基差异百分比在10.7%~61.7%之间, ITS1序列同源性很低,有片段的插入与缺失。种间18S部分序列碱基差异百分比在0.9%~23.7%之间,变化主要是碱基的转换。用邻接法(NJ)构建了8个种的18S部分序列(约240 bp...
肠道微生物与寄主具有复杂的、多方面的相互依存效应,这种依存效应所产生的共生关系或协同进化关系既可反映寄主间的系统演化关系,也可显示肠道微生物间的系统演化关系,共生关系或协同进化关系是由于寄主与肠道微生物两者之间存在着相互自然选择作用所形成的,在长期的进化历程中逐步发生的共生关系信息很可能被记录在DNA序列中。本文通过检测鲤鱼科8种鱼中9种肠道菌群的分布含量对这9种菌群进行分析,且利用从GenBan...

Six male Gayal (Bos frontalis), approximately two years of age and with a mean live weight of 203??7 kg (mean??standard deviation), were housed indoors in metabolism cages and fed bamboo (Sinarundinar...
Seventeen haplotypes were detected from the complete mitochondrial DNA control region sequences analyzed from eighty individuals of two Tibetan domestic sheep breeds. The nucleotide composition of all...
Sulphur River in Parker Cave, Kentucky receives sulfurous water (11–21 mg sulfide/L) from the Phantom Waterfall and contains a microbial mat composed of white filaments. We extend a previous morpholog...
