Creator:: Grote, Jana, Thrash, J. Cameron, Huggett, Megan J., Landry, Zachary C., Carini, Paul, Giovannoni, Stephen J., and Rappe, Michael S.
Abstract:: SAR11 is an ancient and diverse clade of heterotrophic bacteria that are abundant throughout the world's oceans, where they play a major role in the ocean carbon cycle. Correlations between the phylogenetic branching order and spatiotemporal patterns in cell distributions from planktonic ocean environments indicate that SAR11 has evolved into...

Creator:: Temperton, Ben and Giovannoni, Stephen J.
Abstract:: Since nucleic acids were first extracted directly from the environment and sequenced, metagenomics has grown to one of the most data-rich and pervasive techniques for understanding the taxonomic and functional diversity of microbial communities. In the last decade, cheaper sequencing has democratized the application of metagenomics and generated billions of...

Creator:: Ferla, Matteo P., Thrash, J. Cameron, Giovannoni, Stephen J., and Patrick, Wayne M.
Abstract:: Bacteria in the class Alphaproteobacteria have a wide variety of lifestyles and physiologies. They include pathogens of humans and livestock, agriculturally valuable strains, and several highly abundant marine groups. The ancestor of mitochondria also originated in this clade. Despite significant effort to investigate the phylogeny of the Alphaproteobacteria with a...

Creator:: Smith, Daniel P., Thrash, J. Cameron, Nicora, Carrie D., Lipton, Mary S., Burnum-Johnson, Kristin E., Carini, Paul, Smith, Richard D., and Giovannoni, Stephen J.
Abstract:: Nitrogen is one of the major nutrients limiting microbial productivity in the ocean, and as a result, most marine microorganisms have evolved systems for responding to nitrogen stress. The highly abundant alphaproteobacterium “Candidatus Pelagibacter ubique,” a cultured member of the order Pelagibacterales (SAR11), lacks the canonical GlnB, GlnD, GlnK, and...

Creator:: Glass, Jennifer B., Kretz, Cecilia B., Ganesh, Sangita, Giovannoni, Stephen J., Vergin, Kevin L., Ranjan, Piyush, Seston, Sherry L., Buck, Kristen N., Landing, William M., Morton, Peter L., Moffet, James W., and Stewart, Frank J.
Abstract:: Iron (Fe) and copper (Cu) are essential cofactors for microbial metalloenzymes, but little is known about the metalloenyzme inventory of anaerobic marine microbial communities despite their importance to the nitrogen cycle. We compared dissolved O₂ , NO₃⁻, NO₂⁻, Fe and Cu concentrations with nucleic acid sequences encoding Fe and Cu-binding...
