Age really is an issue [PDF]

, 2010
The majority of the source and reservoir rocks for the hydrocarbons in North Sea and the North West Shelf are Jurassic (200–146 Ma) in age. In both the exploration and production phases, the study of palynology, especially fossil dinoflagellate cysts ...

Kabirimine, a New Cyclic Imine from an Okinawan Dinoflagellate

Marine Drugs, 2019
On our quest for new bioactive molecules from marine sources, two cyclic imines (1, 2) were isolated from a dinoflagellate extract, inhibiting the growth of the respiratory syncytial virus (RSV).

Amphidinolides B4 and B5, Potent Cytotoxic 26-Membered Macrolides from Dinoflagellate Amphidinium Species

Marine Drugs, 2005
: Two new cytotoxic 26-membered macrolides, amphidinolides B4 (1) and B5 (2), have been isolated from a marine dinoflagellate Amphidinium sp. (strain Y-100), and the structures were elucidated on the basis of detailed analyses of 2D NMR data including ...

Effect of Grazing-Mediated Dimethyl Sulfide (DMS) Production on the Swimming Behavior of the Copepod Calanus helgolandicus [PDF]

, 2013
Chemical interactions play a fundamental role in the ecology of marine foodwebs. Dimethyl sulfide (DMS) is a ubiquitous marine trace gas that acts as a bioactive compound by eliciting foraging behavior in a range of marine taxa including the copepod ...

Nucleomorph phylogenomics suggests a deep and ancient origin of cryptophyte plastids within Rhodophyta

New Phytologist, EarlyView.
Summary The evolutionary origin of red algae‐derived complex plastids remains obscure. Cryptophyta, one of four eukaryotic lineages harboring these plastids, still contains nucleomorphs, which are highly reduced remnants of red algal nuclei. The genes present on nucleomorph genomes can be used for phylogenomic reconstruction in order to unravel the ...

Non-Conventional Metal Ion Cofactor Requirement of Dinoflagellate Alkaline Phosphatase and Translational Regulation by Phosphorus Limitation

Microorganisms, 2019
Alkaline phosphatase (AP) enables marine phytoplankton to utilize dissolved organic phosphorus (DOP) when dissolved inorganic phosphate (DIP) is depleted in the ocean. Dinoflagellate AP (Dino-AP) represents a newly classified atypical type of AP, PhoAaty.
