Abstract
A new cyanobacterial strain CHAB5880 morphologically identified to the Nostoc-like genus was isolated from wet soil samples in Tibet of China, and it was taxonomically and phylogenetically characterized based on the polyphasic approach combining morphological, genetic and ecological characteristics. Colonies of this strain were usually purple to black, irregularly clustering, forming diffluent mucilage. The phylogenetic tree based on 16S rRNA gene indicated that the novel strain formed a unique cluster, and separated from the 'Nostoc sensu stricto' clade and from the clades of the morphologically similar genera Aliinostoc, Desmonostoc and Holatia. The secondary structure of ITS between 16S-23S rRNA gene in the strain CHAB5880 showed unique patterns of D1-D1', Box-B and V3 helix, which distinguished it from other heterocytous genera. Purpurea tibecum sp. nov. was designated as the type species of the genus.
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.
