Revealing the Diversity of Thin Filamentous Cyanobacteria, with the Discovery of a Novel Species, <i>Pegethrix qiandaoensis</i> sp. nov. (Oculatellaceae, Oculatellales), in a Freshwater Lake in China
During the study of diversity in filamentous cyanobacteria in China, two strains (WZU0719 and WZU0723) with the form of thin filaments were isolated from the surface of Qiandao Lake, a large freshwater lake in Zhejiang Province, China. A comprehensive analysis was conducted, incorporating morphologi...

| description | During the study of diversity in filamentous cyanobacteria in China, two strains (WZU0719 and WZU0723) with the form of thin filaments were isolated from the surface of Qiandao Lake, a large freshwater lake in Zhejiang Province, China. A comprehensive analysis was conducted, incorporating morphological, ecological, and molecular data. The morphological examination provided an initial identification as a <i>Leptolyngbya</i>-like cyanobacterium. Genetic characterization was also performed by amplifying the 16S rRNA gene and the 16S-23S rRNA internal transcribed spacer (ITS) region. The phylogenetic grouping based on the 16S rRNA gene demonstrates that the examined strain is unequivocally assigned to the <i>Pegethrix</i> genus. However, it possesses distinct phylogenetic divergence from the six described <i>Pegethrix</i> species. Additionally, discrepancies in habitat further differentiate it from other members of this genus. Employing the polyphasic approach, we present a comprehensive account of the newly discovered taxa: <i>Pegethrix qiandaoensis</i> sp. nov. The novel taxonomic finding in this research significantly contributes to enhancing the comprehension of <i>Pegethrix</i> diversity across various habitats. |
