Abstract
- Abstract
Soil cyanobacterium, FBCC-A195 were isolated from the soil underneath the Jangnak Bridge, Republic of Korea. The FBCC-A195 was studied using light microscopy (LM), transmission electron microscopy (TEM), 16S rRNA, 16S–23S ITS, and ecological data. FBCC-A195 showed the circular cross-section of the trichome, broad mucilaginous envelopes, a swirl-like pattern of thylakoids inside the cell, and the lowest length/width ratio within the genus. In the 16S rRNA phylogeny, FBCC-A195 showed a sister relationship of Hormoscilla and belonged to the family Gomontiellaceae. The p-distance of FBCC-A195 ranged from 1.7% with H. pringsheimii to 12% with Komvophoron kgarii in the family. In the secondary structure of 16S–23S ITS, D1–D1’, Box-B, and V3 helix of FBCC-A195 were distinguished from those of other taxa in the Gomontiellaceae. Based upon morphological, ecological, and molecular traits, Katagnymene terrestris proved to be a unique and novel species of the Katagnymene.
