DESCRIPTION: Emiliania huxleyi is a numerically and ecologically important phytoplankton species in the ocean known for its cosmopolitan distribution and ability to form large blooms in coastal and open ocean regions. Studies of E. huxleyi variants in culture have found differences in growth, function and activity potential among them. The E. huxleyi variants also differ in some of the genes. This photosynthetic unicellular eukaryote is infected by Emiliania huxleyi viruses (EhV), lytic giant viruses belonging to the genus Coccolithovirus, within the Phycodnaviridae family. These viruses are ubiquitous in the marine environment [ 42 ] and abundant, reaching 10 7 /mL in natural seawater during bloom conditions and from 10 8 to 10 9. tine checks on the assemblage showed that E. huxleyi dom-inated the assemblage throughout the record. 40 fields of view were taken automatically and analyzed with the auto-mated recognition software SYRACO (Beaufort and Doll-fus, 2004). Image analysis was performed on the output files for Emiliania huxleyi to obtain length and weight of the indi

Coccolithoviruses employ a suite of glycosphingolipids (GSLs) to successfully infect the globally important coccolithophore Emiliania huxleyi.Lipid rafts, chemically distinct membrane lipid microdomains that are enriched in GSLs and are involved in sensing extracellular stimuli and activating signalling cascades through protein-protein interactions, likely play a fundamental role in host.
  3. (a) Culture conditions. Monospecific cultures of E. huxleyi (CCMP 371) from the Provasoli-Guillard National Center for Marine Algae and Microbiota were grown in nitrate-limited chemostats (1 l volume) in duplicate under two different treatments. The first treatment represented 'present ocean conditions' with pCO 2 and temperature levels of 383±43 µatm and 20.0±0.1°C, respectively ()

A revised estimate of the relationship between the maximum growth rate (μ max, d −1) of Emiliania huxleyi and temperature (T, °C) was made using quantile regression and literature data from culture experiments (n = 1415).For modeling E. huxleyi bloom formation and coccolithophore functional group growth rate, this relationship is commonly assumed to follow an exponential relationship, as. Here, we experimentally controlled four conditions (light, temperature, pH, and CO 2) to alter the growth rate of Emiliania huxleyi, a biogeochemically important coccolithophorid, and monitored changes in RNA, protein, and carbohydrate content Short-term kinetic experiments, carried out in natural coastal seawater (with predetermined background levels of trace metals and organic ligands, L) enriched with nitrate and phosphate, demonstrated that Emiliania huxleyi was able to uptake Cu very quickly.

Small RNAs (smRNAs) control a variety of cellular processes by silencing target genes at the transcriptional or post-transcription level. While extensively studied in plants, relatively little is known about smRNAs and their targets in marine phytoplankton, such as Emiliania huxleyi (E. huxleyi). Deep sequencing was performed of smRNAs extracted at different time points as E. huxleyi cells. Emiliania huxleyi, the reference species for coccolithophore studies, is contrasted with a range of other species spanning the biodiversity of modern coccolithophores.

Description Emiliania huxleyi: a globular cell of 5 to 8 pm in diame- ter which reaches 10 pm at its maximum. Its cell size depends upon the duration of the light period and on the light intensity. Large cells are produced at long light periods and high light intensities while small cells occur at short light periods and low light intensities. Emiliania huxleyi is the main calcite producer on Earth and is routinely infected by a virus (EhV); a double stranded DNA (dsDNA) virus belonging to the family Phycodnaviridae. E. huxleyi exhibits a haplodiploid life cycle; the calcified diploid stage is non-motile and forms extensive blooms. The haploid phase is a non-calcified biflagellated cell bearing organic scales. Haploid cells are. The aim of this study is to find the algorithms for estimating the biomass of the Emiliania huxleyi from the irradiance data of the sea water surface. For this purpose, the relationships between the biomass of the Emiliania huxleyi in an axenic tank culture and the water irradiance data measured by a spectroradiameter were found Emiliania huxleyi's shapes are as varied as the ocean environments it lives in.

S-EPMC4077253 - Strong shift from HCO3 (-) to CO 2 uptake

ABSTRACT Satellite data show that the distribution of Emiliania huxleyi in the North Sea is characterized by considerable spatial patchiness as well as large annual differences in abundance within any particular area. The causes of this variability are largely unknown, and therefore unpredictable, reflecting a paucity of information on the ecophysiology of the species The species Emiliania huxleyi largely dominates the total coccolithophore production in present day oceans and marine basins, including the Mediterranean Sea. A series of morphometric measurements were performed on the coccoliths of this species to estimate their mass, length and calculate a calcification index (proxy for the size-normalized. The following is an extended summary of the project A model system approach to biological climate forcing: the example of Emiliania huxleyi, that was carried out within the framework of the Dutch National Programme on Air Pollution and Climate Change (NRP) - phase II

  2. Emiliania huxleyi is a unicellular marine phytoplankton species known to play a significant role in global biogeochemistry. Through the dual roles of photosynthesis and production of calcium carbonate (calcification), carbon is transferred from the atmosphere to ocean sediments. Almost nothing is known about the molecular mechanisms that control calcification, a process that is tightly.
  3. Blooms of Emiliania huxleyi have therefore been suggested as potential sources of CO2 for the atmosphere. A model of the carbon budget of phytoplankton blooms by Taylor et al.
