Soil metagenomics with the wetlands team

Jordan, Kelly, and Garrett headed to Lisle, IL last week for the 7th Annual Argonne National Laboratory Soil Metagenomics Meeting.


Jordan had a great time presenting his poster on surface methanogens in wetlands!


Kelly presenting her invited talk “Identifying factors controlling methane emissions across freshwater wetland gradients”


Road trip back to Columbus after a successful, fun meeting!


Genomics resolves two new archaeal phyla

Genomic Expansion of Domain Archaea Highlights Roles for Organisms from New Phyla in Anaerobic Carbon Cycling

Cindy J. Castelle, Kelly C. Wrighton, Brian C. Thomas, Laura A. Hug, Christopher T. Brown, Michael J. Wilkins, Kyle R. Frischkorn, Susannah G. Tringe, Andrea Singh, Lye Meng Markillie, Ronald C. Taylor, Kenneth H. Williams, Jillian F. Banfield


  • Two new archaeal phyla were defined within a recently suggested superphylum
  • Complete and closed genomes have been reconstructed for uncultured Archaea
  • Uncultured Archaea with small genomes have limited metabolic capabilities
  • Novel genome compositions suggest primary roles in carbon and/or hydrogen cycling

Melanie explores Lake Retba Archaea

Unknownimages 2

Melanie De LaRosa, a summer intern from Puerto Rico in the Wrighton lab showcases her research at the undergraduate OSU SROP meeting.  She isolated Archaea adapted to high saline conditions in Lake Retba (lake rose, for it’s pink color caused by the microbes) in Senegal, Africa. Many thanks to Prof. John Reeve, Prof. Chuck Daniels (both in the OSU Micro department), and SROP ( for their support.
