TLDR
Observations suggest that P. foliaceum contains a membrane‐bound endosymbiont, similar to that already described for the closely related species P. balticum (Levander) Lemmermann.Abstract:
SUMMARY
The fine structure of the binucleate, fucoxanthin-containing dinoflagellate Peridinium foliaceum (Stein) Biechler was re-examined for evidence of an endosymbiout. The eucaryotic nucleus, chloroplasts and associated ribosome-dense cytoplasm were separated by a single invaginating membrane from the rest of the dinoflagellate cell. The triple membrane-enclosed eyespot, mesocaryotic nucleus, trichocysts and accumulation bodies resided in the dinoflagellate cytoplasm. These observations suggest that P. foliaceum contains a membrane-bound endosymbiont, similar to that already described for the closely related species. P. balticum (Levander) Lemmermann.read more

Dinoflagellate nuclear SSU rRNA phylogeny suggests multiple plastid losses and replacements.
TL;DR: To trace the gain and loss of plastids in dinoflagellates, the nuclear small subunit rRNA gene is sequenced of 28 photosynthetic and four non-photosynthetic species, and phylogenetic trees with a total of 81 dinof lagellate sequences are produced.

TL;DR: It is recommended that the classical method of counting phytoplankton for crop estimates be supplemented by chemotaxonomical studies with modern quantitative chromatographic methods such as HPLC for the measurement of algal pigments.

A low-viscosity epoxy resin embedding medium for electron microscopy.
TL;DR: A low-viscosity embedding medium based on ERL-4206 is recommended for use in electron microscopy and has a long pot life of several days and infiltrates readily because of its low viscosity.

Chloroplast pigment patterns in dinoflagellates1
TL;DR: The chlorophylls and carotenoids of 22 species of dinoflagellates were analysed by thin layer chromatography, using 2-dimensional sucrose plates, and 1-dimensional polyethylene plates for CHs c1 and c2 as mentioned in this paper.

TL;DR: The ultrastructure of Peridinium balticum indicates that an eudosymbiont is present within the dinoflagellate, and the origin of photosynthetic dinofLagellates from heterotrophic forms by means of a chrysophyte‐like endosymbIONt is postulated.

Chloroplast pigments of the marine dinoflagellateGyrodinium resplendens.
TL;DR: The photosynthetic marine dinoflagellate, Gyrodinium resplendens, was grown axenically and harvested during logarithmic growth for analysis of its lipid-soluble pigments, confirming the presence of β-carotene, peridinin, dinoxanthin and diadinoxanth in as major carotenoids and four new minor xanthophylls are described.
