Fig. 1From: Genome-scale identification and comparative analysis of transcription factors in thermophilic cyanobacteriaPhylogenetic inference of 16Â S rRNA gene sequences representing 128 cyanobacterial strains. Collapsed genera are indicated by black polygons, with a length corresponding to the distance from the most basal sequence to the most diverged sequence of the genus. The thermophilic cyanobacteria are in boldBack to article page
