The effects of growth conditions on the elemental and biochemical composition of the diatom Thalassiosira weissflogii and the haptophyte Emiliania huxleyi
… effect of temperature was observed in the marine haptophyte Emiliania huxleyi (CCMP 1516) at nutrient replete semi-continuous cultures. Triplicate cultures were incubated different temperature from 14 to 22oC and under photon flux densities (PFD) 600 μmol photons m−2 s−1. The growth rate (GR) of …

Feeding, Dark Survival, and Foreign Organelle Retention in an Antarctic Dinoflagellate
… Sea, Antarctica (RSD) retains plastids from its haptophyte prey Phaeocystis antarctica. It is a member of the Kareniaceae, a dinoflagellate family whose other members all contain permanent tertiary plastids of haptophyte origin. A subset of its cells also contain foreign nuclei. The following …

THE ORIGIN OF THE DINOFLAGELLATE PLASTID
… that the plastid donor could have been a haptophyte. In an attempt to find better genes for analysis and to further understand gene transfer about 4900 randomly selected expressed genes were sequenced from two dinoflagellates, <i>Lingulodinium polyedra</i> and <i>Amphidinium carterae</i>. …

Determination of sediment provenance at drift sites using hydrogen isotopes in lipids
… alkenones from cultured unicellular algae (haptophyte Emiliania huxleyi), surface ocean particulate material, and open ocean sediments to determine the extent and variability of hydrogen isotopic fractionation in the di-, tri-, and tetraunsaturated C₃₇ compounds. We then compared the …

Defining the ecological and physiological traits of phytoplankton across marine ecosystems
… The second field study focused on the diatom, haptophyte, and dinoflagellate functional groups, using simulated blooms to characterize the traits that govern the magnitude and timing of phytoplankton blooms in the oligotrophic ocean. The results indicated that blooms form when phytoplankton are …

Microbial biodiversity in the southern Indian Ocean and Southern Ocean
… Ocean with a concomitant increase in the haptophyte community. Whilst the virome confirmed the dominance of tailed phages and giant viruses across all stations, there was a significant variation caudoviruses and Nucleocytoplasmic Large DNA viruses (NCLDV) across defined biogeographical …

Coevolution of plastid genomes and transcript processing pathways in photosynthetic alveolates
… poly(U) tail addition and editing occur in the haptophyte-derived serial endosymbionts of the fucoxanthin-containing dinoflagellates Karenia mikimotoi and Karlodinium veneficum. This is the first evidence that plastids acquired through serial endosymbiosis may be supported by pathways retained …

Annotation and comparative analysis of fungal genomes: a hitchhiker's guide to genomics
… and Candida bombicola, as well as the one of the haptophyte Emiliania huxleyi CCMP1516. These species are important organisms in many aspects, for instance: L. bicolor and G. intraradices are symbiotic fungi growing associate with trees and present an important ecological niches for promoting tree …
