Distribution and Genomic Variation of Thermophilic Cyanobacteria in Diverse Microbial Mats at the Upper Temperature Limits of Photosynthesis.

ABSTRACT: Thermophilic cyanobacteria have been extensively studied in Yellowstone National Park (YNP) hot springs, particularly during decades of work on the thick laminated mats of Octopus and Mushroom springs. However, focused studies of cyanobacteria outside these two hot springs have been lacking, especially regarding how physical and chemical parameters along with community morphology influence the genomic makeup of these organisms. Here, we used a metagenomic approach to examine cyanobacteria existing at the upper temperature limit of photosynthesis. We examined 15 alkaline hot spring samples across six geographic areas of YNP, all with various physical and chemical parameters and community morphology. We recovered 22 metagenome-assembled genomes (MAGs) belonging to thermophilic cyanobacteria,
