Microbial mat communities that inhabit hot springs in Yellowstone National Park have been studied for their biodiversity, energetics and evolutionary history, yet little is know about how these communities cope with nutrient limitation. In the present study the changes in assimilatory gene expression levels for nitrogen (nrgA), phosphorus (phoA), and iron (yusV) were measured under various nutrient enrichment experiments. While results for nrgA and phoA were inconclusive, results for yusV showed an increase in expression with the addition of N and Fe.
