摘要

新分类群Paraeustigmatos columelliferus是从美国阿肯色州蒙蒂塞洛湖岸边的丝状藻Zygnema群中分离出来的。18S rDNA和rbcL序列的系统发育分析结果表明，该藻可能与真藻属同源;或者，它可能代表这个类的新的第三个分支。光镜和电子显微镜显示其细胞特征与真棘科其他成员相似;然而，细胞壁具有不同寻常的结构，类似于花粉粒壁的小柱。

Phylogeny and characterization of Paraeustigmatos columelliferus, gen. et sp. nov., a member of the Eustigmatophyceae that may represent a basal group within the Eustigmatales

The new taxon, Paraeustigmatos columelliferus, was isolated from a mat of the filamentous alga Zygnema on the shore of Lake Monticello in Arkansas, USA. The results of the phylogenetic analysis of 18S rDNA and rbcL sequence data suggest that this alga is likely allied with the Eustigmatales; alternately, it may represent a new third linage of the class. Light and electron microscopy reveal cellular features similar to other members of the Eustigmatophyceae; however, the cell wall bears unusual structures that resemble the columellae of the walls of pollen grains.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
