WALNUT CREEK, Calif.The U.S. Department of Energy (DOE) Office of Science Early Career Research Program has awarded a grant to DOE Joint Genome Institute scientist Susannah Green Tringe to conduct genomic studies of microbial communities (metagenomes) in restored wetlands around the San Francisco Bay-Delta region of California.
Tringe, who heads the DOE JGI Metagenome Program, and 64 other applicants had been awarded funding for their projects from more than 1,100 proposals received.
Tringe plans to use the five-year grant to study the roles microbial communities play in restored wetlands, and their impact on long-term carbon sequestration, from a genomic perspective. "Restoration of wetlands has the potential to remove significant amounts of carbon dioxide from the atmosphere, due to rapid accumulation of emergent vegetation and low rates of biomass decomposition in the anoxic soil," she wrote in her proposal. "Most of the long-term carbon storage takes place in the soil or sediment, yet little is known about the belowground microbial communities that are likely key determinants of the relative balance between carbon storage and atmospheric recycling."
"This is a very well-deserved honor for Susannah," said Eddy Rubin, DOE JGI Director, who mentored Tringe over the last eight years along her upward career trajectory at the Institute. "She has been a major contributor to ground-breaking comparative analyses of environmental microbial communities that have been published in some of the highest impact journalsScience and Nature."
The first year of Tringe's awarded study will focus on the restored wetlands of Twitchell Island in the Sacramento/San Joaquin Delta. Studies conducted by the U.S. Geological Survey indicate that the area has a carbon sequestration rate of 1 kilogram per square meter per year, which, Tringe said, "is comparable to, if not greater than" the carbon sequestration rates achieved from tropical reforestat
