FIGURE 4. Alignment of the 16S–23S rRNA internal transcribed spacer (ITS) region from Nostoc sp. and Wilmottia members. The different conserved domains (D1–D5), the tRNA genes, the major variable stems V2 and V3, and the antiterminator (Box B and Box A) are indicated by boxes and names. The Nostoc sequence contains both tRNAIle and tRNAAla, whereas all Wilmottia have only single tRNAIle. All the compared sequences contain all important structural elements of the ITS, as described by Boyer et al. (2001).

FIGURE 3. Maximum-likelihood (ML) tree of the phylogenetic relationships of species within the family Coleofasciculaceae (Geitlerinema, Potamolinea, Pycnacronema and Wilmottia) inferred from nearly complete 16S rRNA gene sequences, using Arthrospira platensis (CP013008) (Microcoleaceae) as the outgroup. Bayesian analysis was similar in topology of the ML tree and thus, its posterior probabilities (PP) are incorporated into the tree. Nodes display ML bootstrap support (> 50%) and Bayesian posterior probabilities (> 0.50), respectively. The branch lengths are proportional to the scale given.

FIGURE 6 in Morphology and molecular description of Wilmottia koreana sp. nov. (Oscillatoriales, Cyanobacteria) isolated from the Republic of Korea

FIGURE 6. Nucleotide divergence of the Wilmottia 16S rRNA gene sequences (datasets used in Table 3) based on corrected p-distances. Genetic distances between each paired sequence were calculated by the Kimura 2-parameter model, where a total of 3 Wilmottia species (23 sequences) were compared. Bar heights indicate % p-distance measured for W. murrayi (Wm), W. stricta (Ws), and inter-species (e.g., W. koreana (Wk)). The values are shown as mean ±SD (Standard Deviation). Statistical analysis showed that the 16S rRNA gene divergences were significantly different between Wilmottia inter-species, but not intra-species (Student's t-test, ***P <0.01; N = 190 in Wm, 40 in Wm vs. Ws, 20 in Wm vs. Wk, and 2 in Wk vs. Ws respectively).
