Candidatus Pelagibacter ubique, a cultivated representative of the SAR11 clade, which is the most abundant clade in the oceans&amp;nbsp;4, has a small, streamlined genome and possesses an unusually small number of transcriptional regulators. This observation leads to the hypothesis that transcriptional control is low in Pelagibacter and limits its response to environmental conditions. However, the extent of transcriptional control in Pelagibacter is unknown. Overall design: Bacteria were grown in batch culture and sampled twice during the initial, rapid phase of exponential growth and twice during the phase of slower growth that followed.&amp;nbsp; Transcripts deposited here were assessed using RNA-seq.&lt;/p&gt; Methods and Sampling: &lt;p&gt;&lt;strong&gt;Sampling and Analytical Methodology&amp;nbsp;&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;Bacterial strains. Pelagibacter ubique strain HTCC1062 and Gammaproteobacteria SAR92 strain HTCC2207 were obtained from S. Giovannoni (Oregon State University). Polaribacter strain MED152 was obtained from J. Pinhassi (Linnaeus University, Sweden). Ruegeria pomeroyi strain DSS-3 was obtained from Mary Ann Moran (University of Georgia).&lt;/p&gt; &lt;p&gt;Growth media and conditions. Pelagibacter and SAR92 were grown in a defined medium containing artificial seawater salts AMS1 (Carini et al. 2013) with additions of pyruvate, glycine, methionine and other organic substrates plus vitamins as described by (Steindler et al. 2011). Ruegeria was grown using YTSS medium that includes 0.4 g L-1 yeast extract and 0.25 g L-1 tryptone added to artificial seawater salts (Sigma-Aldrich). MED152 was grown in a medium with 5 g L-1 of peptone and 1 g L-1 of yeast extract added to the AMS1 salt solution. Cultures were maintained at 19°C in the dark and were aerated by bubbling with 0.2 µm filtered air or by rotary shaking.&lt;/p&gt; &lt;p&gt;Growth rates. Bacterial abundance was monitored by flow cytometry using a BD FACSCalibur of samples stained with SYBR Green I (Invitrogen) at a concentration of 1:2,000 of the manufactures supplied concentration for 30 min. Growth rates were calculated from the rate of change of bacterial abundance over time.&lt;/p&gt; &lt;p&gt;Nucleic acid extraction. Bacterial biomass was collected by vacuum filtration using 0.2 µm-pore-size Durapore (Millipore) filters. The filters were stored at -80°C in RLT buffer until DNA and RNA were extracted using the AllPrep DNA/RNA (Qiagen) kit following the manufacturer's instructions.&lt;/p&gt; &lt;p&gt;RNA sequencing abundance standard. Internal standard RNA molecules were used to obtain absolute quantification of transcripts based on the number of standard molecules added at the beginning of sample processing and those recovered in the sequence library (Moran et al. 2013, Satinsky et al. 2013). RNA standards were prepared using in vitro transcription (RiboMax Large Scale RNA Production Systems, Promega) from plasmid templates pTXB1 (New England BioLabs) and pFN18K (Promega), yielding single stranded RNA transcripts of 917 nt and 970 nt, respectively.&amp;nbsp;&amp;nbsp; The RNA standards were added immediately before nucleic acid extraction at a concentration of 0.5% by mass of the total RNA yield in the sample (Moran et al. 2013, Satinsky et al. 2013).&lt;/p&gt; Funding provided by NSF Division of Ocean Sciences (NSF OCE) Award Number: OCE-1343773 Award URL: https://www.nsf.gov/awardsearch/show-award?AWD_ID=1343773 onGoing Dr Matthew T Cottrell University of Delaware 302-645-4383 School of Marine Science and Policy 700 Pilottown Road Lewes DE 19958 USA mattcott@udel.edu pointOfContact asNeeded Dataset Version: 2016.03.03 Unknown Genbank Accession Number Illumina HiSeq 2500 theme None, User defined accession number featureType BCO-DMO Standard Parameters Automated DNA Sequencer instrument BCO-DMO Standard Instruments otherRestrictions otherRestrictions Access Constraints: none.

Coordination of respiratory gene transcription and respiration in cultivated marine bacteria https://osprey.bco-dmo.org/project/544923 Coordination of respiratory gene transcription and respiration in cultivated marine bacteria <p>Heterotrophic bacteria account for about half of the respiration in the oceans and they are the main consumers of dissolved organic materials, converting approximately 80% of assimilated organic carbon to carbon dioxide. Detailed examinations of the structure of microbial communities reveal that a highly diverse community of microorganisms must be responsible for the conversion of organic materials in the oceans. Recent studies suggest that most of growth-related activity is associated with a rather small number of abundant bacteria in the oceans. It is unclear, however, if the same observation applies to respiration, the dominant fate of organic carbon in the oceans. We currently lack tools for assessing respiration by specific microbes and for linking specific taxa with their contribution to carbon conversion and to carbon cycling.</p> <p>The aim of this project is to develop a tool for understanding the contribution of bacterial groups to bacterial respiration. The proposed work will determine the relationship between transcription levels of oxidative phosphorylation genes and respiration rates in cultivated marine bacteria. The culture-based work is a necessary prerequisite to develop a metatranscriptomic tool for addressing ecological questions about the role of bacterial diversity in ocean carbon cycling. The project will include chemostat and batch culture studies with pure cultures and an incubation experiment with a naturally community of estuarine bacteria. Laboratory experiments will examine important heterotrophic bacteria in the oceans such as Pelagibacter ubique of the SAR11 clade and Ruegeria pomeroyi of the Roseobacter clade. Existing genome sequences will be analyzed to address the phylogenetic resolving power of respiration genes. The overarching goal of this proposal is to determine the relationship between abundances of respiration gene transcripts and respiration rates for bacterial taxa defined at different phylogenetic distances.<br />  </p> EAGER Respiration largerWorkCitation project eng; USA biota oceans 2016-03-03 Laboratory in Lewes, DE: 38.785289 N, 75.160167 W 0 BCO-DMO catalogue of parameters from Laboratory results containing transcripts of four cultivated marine bacteria from 2014-2015 (EAGER Respiration project) Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact http://lod.bco-dmo.org/id/dataset-parameter/639665.rdf Name: Genbank Accession Number Units: dimensionless Description: <p>GenBank Accession Number corresponding to the RNA-seq data deposited with NCBI.</p> GB/NERC/BODC > British Oceanographic Data Centre, Natural Environment Research Council, United Kingdom Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact https://osprey.bco-dmo.org/dataset/639613/data/download download onLine dataset &lt;p&gt;&lt;strong&gt;Sampling and Analytical Methodology&amp;nbsp;&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;Bacterial strains.
