Abstract

A novel filamentous, nonheterocytous cyanobacterium was isolated from Lagos Lagoon, Nigeria. The isolate was <3.0 µm wide, untapered, with small rounded polar bodies (aerotopes or cyanophycin granules) visible at the crosswalls, and consequently fit the morphological description of Limnothrix planctonica. Although morphologically inseparable from that species, it was molecularly distant from that taxon, with genetic identities between the two taxa ranging 90.73-92.49%, a degree of separation typical of different genera. Both taxa, as well as Limnothrix rosea, are phylogenetically in the Prochlorotrichaceae, distant from the type species of Limnothrix, L. redekei, which is in the Pseudanabaenaceae. The isolate is herein described as Lagosinema tenuis gen. et sp. nov.

Lagosinema tenuis gen. et sp. 11 .(原绿藻科，蓝藻门):来自热带非洲的咸淡水新属

从尼日利亚拉各斯泻湖分离到一种新型丝状非异源细胞蓝细菌。该分离物宽度<3.0µm，未经处理，侧壁可见小的圆形极性体（aerotopes或蓝藻素颗粒），因此符合平核新月星的形态描述。尽管在形态上与该物种不可分割，但在分子上与该分类单元相距甚远，两个分类单元之间的遗传同一性范围为90.73-92.49%，这是不同属的典型分离程度。这两个分类群，以及玫瑰月见草，在系统发育上都属于原氯虫科，与月见草的模式种L.redekei相距甚远，后者属于Pseudanabaenaceae。该分离物在本文中被描述为Lagosinema tenuis gen.et sp.nov。

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.
