(Public Library of Science, 2010-02)
    Background: Bacterial viruses (phages) play a critical role in shaping microbial populations as they influence both host mortality and horizontal gene transfer. As such, they have a significant impact on local and global ...

    Our understanding of secondary metabolite production in bacteria has been shaped primarily by studies of attached varieties such as symbionts, pathogens, and soil bacteria. Here we show that a strain of the single-celled, ...

    The marine cyanobacterium Prochlorococcus MED4 has the smallest genome and cell size of all known photosynthetic organisms. Like all phototrophs at temperate latitudes, it experiences predictable daily variation in available ...
  • Becker, Jamie William; Berube, Paul M.; Follett, Christopher L.; Waterbury, John B.; Chisholm, Sallie (Penny); DeLong, Edward; Repeta, Daniel J. (Frontiers Research Foundation, 2014-03)
    Production of dissolved organic matter (DOM) by marine phytoplankton supplies the majority of organic substrate consumed by heterotrophic bacterioplankton in the sea. This production and subsequent consumption converts a ...
  • Coleman, Maureen L.; Chisholm, Sallie (Penny) (National Academy of Sciences (U.S.), 2010-10)
    Bacterial populations harbor vast genetic diversity that is continually shaped by abiotic and biotic selective pressures, as well as by neutral processes. Individuals coexisting in the same geographically defined population ...
  • Kelly, Libusha; Ding, Huiming; Huang, Katherine H.; Osburne, Marcia; Chisholm, Sallie (Penny) (Nature Publishing Group, 2013-05)
    Viruses that infect marine cyanobacteria–cyanophages–often carry genes with orthologs in their cyanobacterial hosts, and the frequency of these genes can vary with habitat. To explore habitat-influenced genomic diversity ...
  • Sullivan, Matthew B.; Krastins, Bryan; Hughes, Jennifer L.; Hughes, Jennifer L.; Kelly, Libusha; Chase, Michael; Sarracino, David; Chisholm, Sallie (Penny) (2009-10)
    Prochlorococcus, an abundant phototroph in the oceans, are infected by members of three families of viruses: myo-, podo- and siphoviruses. Genomes of myo- and podoviruses isolated on Prochlorococcus contain DNA replication ...

    The marine cyanobacterium Prochlorococcus is the numerically dominant photosynthetic organism in the oligotrophic oceans, and a model system in marine microbial ecology. Here we report 27 new whole genome sequences (2 ...
  • Labrie, Simon J.; Frois-Moniz, Katya; Osburne, Marcia; Kelly, Libusha; Roggensack, Sara; Sullivan, M. B.; Gearin, G.; Zeng, Q.; Fitzgerald, M.; Henn, M. R.; Chisholm, Sallie (Penny) (Wiley Blackwell, 2013-01)
    The marine cyanobacteria Prochlorococcus and Synechococcus are highly abundant in the global oceans, as are the cyanophage with which they co-evolve. While genomic analyses have been relatively extensive for cyanomyoviruses, ...
  • Sullivan, Matthew B.; Huang, Katherine H.; Ignacio-Espinoza, Julio C.; Berlin, Aaron M.; Kelly, Libusha; Weigele, Peter; DeFrancesco, Alicia S.; Kern, Suzanne Elizabeth; Thompson, Luke Richard; Young, Sarah; Yandava, Chandri; Fu, Ross; Krastins, Bryan; Chase, Michael; Sarracino, David; Osburne, Marcia; Henn, Matthew R.; Chisholm, Sallie (Penny) (Society for Applied Microbiology and Blackwell Publishing Ltd, 2010-11)
    T4-like myoviruses are ubiquitous, and their genes are among the most abundant documented in ocean systems. Here we compare 26 T4-like genomes, including 10 from non-cyanobacterial myoviruses, and 16 from marine ...
  • Klein, Michael G.; Zwart, Peter; Bagby, Sarah C.; Cai, Fei; Chisholm, Sallie (Penny); Heinhorst, Sabine; Cannon, Gordon C.; Kerfeld, Cheryl A. (Elsevier, 2009-09)
    Bacterial microcompartments (BMCs) are polyhedral bodies, composed entirely of proteins, that function as organelles in bacteria; they promote subcellular processes by encapsulating and co-localizing targeted enzymes with ...
  • Zeng, Qinglu; Chisholm, Sallie (Penny) (Elsevier, 2012-01)
    Phosphorus (P) availability, which often limits productivity in marine ecosystems, shapes the P-acquisition gene content of the marine cyanobacteria Prochlorococcus [ [1], [2], [3] and [4]] and its viruses (cyanophages) [ ...
  • McCarren, Jay; Becker, Jamie William; Repeta, Daniel J.; Shi, Yanmei; Young, Curtis Robert, III; Malmstrom, Rex R.; Chisholm, Sallie (Penny); DeLong, Edward (National Academy of Sciences, 2010-08)

  • Chisholm, Sallie (Penny); Follows, Michael J.; Jahn, Oliver; Dutkiewicz, Stephanie; Bragg, Jason G. (Public Library of Science, 2010-03)
    Our view of marine microbes is transforming, as culture-independent methods facilitate rapid characterization of microbial diversity. It is difficult to assimilate this information into our understanding of marine microbe ...
  • Chisholm, Sallie (Penny); Bragg, Jason G. (Public Library of Science, 2008-10)
    Background: Phages infecting marine picocyanobacteria often carry a psbA gene, which encodes a homolog to the photosynthetic reaction center protein, D1. Host encoded D1 decays during phage infection in the light. Phage ...
