1西北太平洋浮游有孔虫的SSU rDNA序列及其古海洋学意义显示文摘研究对采集于西北太平洋冲绳海槽表层水体中的活浮游有孔虫进行DNA分析尝试,获得了西北太平洋浮游有孔虫Pulleniatina obliquiloculata和Globigerina sp.等的SSUrDNA序列特征,并与南太平洋地区属种的DNA序列进行对比.结果显示两不同海区P. obliquiloculata个体的SSUrDNA差异与同一个体内不同拷贝序列间差异类似,仅为0.7%-1.2%.详细比较研究认为,传统微体古生物形态学定义种对西北太平洋与南太平洋的P.obliquiloculata来说具有可靠的分子生物学证据.李保华 李铁刚 Kermal Topac Ertan Christoph Hemleben 李春香 曹奇原 杨群 2007自然科学进展2007,17,3:5
2有孔虫分子生物学研究进展显示文摘传统的微体古生物学研究中,有孔虫是生活于海洋环境中以具有膜状、胶结质或钙质壳为特征的丝网状肉足虫类原生动物.最近对底栖有孔虫rDNA序列的分析研究,揭示了有孔虫还有无壳(裸露)种类以及生活于陆地淡水环境的类型. 同时分子系统学研究表明有孔虫位于真核生物系统树的基部,在双滴虫类与绿眼虫类之间.对浮游有孔虫大量基因型及其与环境关系的研究, 揭示了传统研究低估了有孔虫的多样性.有孔虫基因型与生物地理分布、海洋环境有关研究表明利用rDNA序列分析识别出的同一物种的不同基因型可以为古环境研究提供更加精确的替代性指标.李保华 Kemal Topac Ertan Christoph Hemleben 2005自然科学进展2005,15,5:3
