Phylogenetic Analysis of a Privately-owned Korean Native Chicken Population Using mtDNA D-loop Variations
D-loop Variation Haplotype Korean Native Chicken mtDNA
2016/5/11
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...
双壳纲动物核糖体RNA 18S-ITS1序列及其在分子系统发育研究中的应用18S-ITS1 Sequence of rRNA in Bivalves and its Application in Phylogenetic Analysis
ITS1 18S RNA 遗传多样性 双壳纲
2008/1/20
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...
