Project description:We investigated an alga-dominated geothermal spring community in Yellowstone National Park (YNP), USA to determine how the biota cope with abiotic stressors. Microbes showed a community level response to toxic metal resistance and energy cycling that spans the three domains of life. Arsenic detoxification is accomplished via complementary expression of genes by different lineages. Photosynthetic primary production is dominated by the obligate photoautotrophic alga Cyanidioschyzon, with the mixotroph, Galdieria, largely relegated to nighttime heterotrophy. Many key functions, including the cell cycle, are strongly regulated by diurnal fluctuations in light and nutrients. These results demonstrate that biotic interactions are highly structured and constrained in extreme habitats. We suggest this was also the case on the early Earth when geothermal springs were cradles of microbial life.

Project description:The thermophilic Aquificales inhabit and play important biogeochemical roles in the geothermal environments globally. Although intensive studies on physiology, microbial ecology, biochemistry, metagenomics and metatranscriptomics of the Aquificales¬ species and Aquificales-containing environmental samples have been conducted, comprehensive understandings about their ecophysiology, especially in the natural niches have been limited. In the present study, an integrated suite of metagenomic, metatranscriptomic and metaproteomic analyses, for the first time, were conducted on a filamentous microbial community from the Apron and Channel Facies (ACF) of CaCO3 (travertine) deposition at Narrow Gauge, Mammoth Hot Springs, Yellowstone National Park.
