Project description:Our paper presents the results of a study in which we used whole genome bisulfite sequencing (WGBS), RNA-Seq (i.e. transcriptomics), high-CO2 physiology experiments, and spatiotemporally separated samples isolated in situ (i.e. directly from the ocean) to examine the metabolic potential of genome-wide cytosine (5mC) methylation (i.e. epigenomics), its potential impacts to transcriptional dynamics under both present-day and future ocean acidification conditions, and its biogeographic conservation in the globally-significant, biogeochemically-critical marine cyanobacterium Trichodesmium.
Project description:This project presents field metaproteomics data from Trichodesmium colonies collected from the surface ocean. Most were collected from the tropical and subtropical Atlantic ocean, but there is also data from the long term Bermuda Atlantic Time Series and Hawaii Ocean Time Series. Trichodesmium is a globally important marine microbe and its growth and nitrogen fixation activity is limited by nutrient availability in the surface ocean. This dataset was generated to answer questions about limitations on Trichodesmium's growth and activity in the nature.
