Newly recorded genera and species, Pantanalinema rosaneae and Alkalinema pantanalense (Leptolyngbyaceae, Cyanobacteria) isolated in Korea

다국어 초록 (Multilingual Abstract)

Two strains of cyanobacteria were isolated from the soil of Seodaemun-gu, Seoul and from the gravel of the Ansung Stream, Gyeonggi Province, Korea, respectively. They were identified as Pantanalinema rosaneae and Alkalinema pantanalense under the Leptolyngbyaceae through the morphological, ecological, and molecular analyses and first reported in Korea. Belonging to the Leptolyngbya morphotypes, they are thin filamentous cyanobacteria and morphologically indistinguishable cryptic species. The strains of P. rosaneae and A. pantanalense isolated in Korea revealed the same cluster as their type species in the phylogenetic analysis using the 16S rRNA gene sequences, and similarities in the secondary structures of 16S-23S ITS sequences. Although both P. rosaneae and A. pantanalense were collected from water samples in the Pantanal wetland of Brazil, the P. rosaneae obtained in Korea, was soil-dwelling subaerophytic species whereas A. pantanalense was epilithic species living on gravel in the freshwater. Therefore, they are considered to have an extensive habitat
