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...
