Genetic diversity on the Genus Skeletonema (Bacillariophyceae) in the coastal waters of China

骨条藻（Skeletonema）是一类广泛分布于沿海水域的浮游硅藻，也是常见的赤潮生物。目前，对于整个中国沿海骨条藻的分类和分子生物学方面的研究，比较分散，还不能很好地回答我国沿海骨条藻的种类多样性和遗传多样性的问题。因此，本文选择我国沿海的代表性海区，进行周年采样，对分离培养的纯种株系，选择核糖体LSUnrDNA和ITS片段（5.8SrDNA及转录间隔区ITS1、ITS2）对其进行遗传多样性及系统进化分析，旨在从分子生物学方面分析我国沿海骨条藻属的种内、种间和地理株系间的差异，以及系统进化关系，探讨我国沿海骨条藻属的遗传多样性。主要研究结果如下： 1.从大连、青岛、宁波、福建、深圳、香港、...Skeletonema is a worldwide distributed planktonic diatom in coastal water which is also a common red-tide organism. There have been few studies on taxonomy and molecular biology of Skeletonema in the China sea, and that the species and genetic diversity of Skeletonema in China sea keeps poorly known. Therefore, water samples were sampled seasonly at the typical waters of China coastal during 2013 ...学位：理学硕士院系专业：生命科学学院_水生生物学学号：2162012115237
