Journal ArticleDOI
Viruses infecting a warm water picoeukaryote shed light on spatial co-occurrence dynamics of marine viruses and their hosts
Charles Bachy,Charles Bachy,Charmaine C. M. Yung,Charmaine C. M. Yung,Charmaine C. M. Yung,David M. Needham,David M. Needham,Maria Consuelo Gazitúa,Simon Roux,Simon Roux,Alexander J. Limardo,Chang Jae Choi,Chang Jae Choi,Danielle M. Jorgens,Matthew B. Sullivan,Alexandra Z. Worden,Alexandra Z. Worden,Alexandra Z. Worden +17 more
TL;DR: In this paper, the authors isolated three dsDNA prasinoviruses from the Sargasso Sea against Bathycoccus calidus isolate RCC716 and proposed that molecular diversity within this new species likely connects to the differentiated host-virus dynamics observed in their time course experiments.

Dynamics and interactions of highly resolved marine plankton via automated high frequency sampling
David M. Needham,Erin B. Fichot,Ellice Wang,Lyria Berdjeb,Jacob A. Cram,Cédric G. Fichot,Jed A. Fuhrman +6 more
TL;DR: In this paper, the small sub-unit ribosomal RNA gene (rRNA gene) and rRNA molecules (rRN) of Bacteria, Archaea, and Eukaryota were sequenced once to twice-daily between March 2014 and May 2014 from the surface ocean off Catalina Island, California.

Taxon disappearance from microbiome analysis indicates need for mock communities as a standard in every sequencing run
TL;DR: It is suggested that using mock communities in every sequencing run is essential to distinguish potentially serious aberrations from natural variations, and assuming that the microbiome sequencing analysis works properly every time risks serious errors that can be avoided by the use of suitable mock communities.

Dynamics of finely resolved, abundant symbiotic marine plankton and other interacting microbes via automated high-frequency sampling
David M. Needham,Erin B. Fichot,Ellice Wang,Lyria Berdjeb,Jacob A. Cram,Cédric G. Fichot,Jed A. Fuhrman +6 more
TL;DR: The utility of high-frequency time-series to show rapid microbial reactions to stimuli is reiterated, and new information about in-situ dynamics of previously recognized and hypothesized interactions is provided.
Posted ContentDOI
Dynamic marine viral infections and major contribution to photosynthetic processes shown by regional and seasonal picoplankton metatranscriptomes
TL;DR: It is demonstrated that published T4-like cyanophages and pelagiphages, having genomic continuity between close relatives, are better tracked using marker genes, and determination of potential hosts by matching infection dynamics with microbial community composition is demonstrated.
