PHOTOSYNTHETIC PIGMENTS OF SYMBIOTIC DINOFLAGELLATES (ZOOXANTHELLAE) FROM CORALS AND CLAMS
1. The photosynthetic pigments of the brown symbiotic algae (zooxanthellae) isolated from five tridacnid clams and nine corals were found to be identical with the pigments of the dinoflagellate…
PHOTOSYNTHETIC ACTION SPECTRA OF MARINE ALGAE
A polarographic oxygen determination, with tissue in direct contact with a stationary platinum electrode, has been used to measure the photosynthetic response of marine algae. These were exposed to…
CHLOROPLAST PIGMENT PATTERNS IN DINOFLAGELLATES 1
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…
Molecular topology of the photosynthetic light-harvesting pigment complex, peridinin-chlorophyll a-protein, from marine dinoflagellates.
The photosynthetic light-harvesting complex, peridinin-chlorophyll a-protein, was isolated from several marine dinoflagellates including Glenodinium sp. by Sephadex and ion-exchange chromatography.…
PHOTOSYNTHETIC ACTION SPECTRUM OF THE COCCOLITHOPHORID, EMILIANIA HUXLEYI (HAPTOPHYCEAE): 19′ HEXANOYLOXYFUCOXANTHIN AS ANTENNA PIGMENT 1, 2

19′ hexanoyloxyfucoxanthin is considered to be an efficient antenna pigment for photosynthesis and to be preferentially associated with photosystem II, and may be a quantitatively significant light harvesting pigment for some algae of the marine environment.
LIGHT TRANSMISSION AND SPECTRAL DISTRIBUTION THROUGH EPI- AND ENDOZOIC ALGAL LAYERS IN THE BRAIN CORAL, FAVIA
Two species of algae were living symbiotically with a hard brain coral, Fa@ia, harvested in the environs of the Flinders Island Group on the Great Barrier Reef in Australia, and their in vivo absorption spectra as well as the spectral distribution were described.
Carotenoids of the dinophyceae
Peridinin-Chlorophyll a Proteins of the Dinoflagellate Amphidinium carterae (Plymouth 450).
Fluorescence excitation and emission spectra demonstrate that light energy absorbed by peridinin induces chlorophyll a fluorescence presumably by intramolecular energy transfer, suggesting that the naturally occurring proteins are deamidation products of a single protein.
Spectral properties and photosynthetic action in red-tide populations of Prorocentrum micans and Gonyaulax polyedra
The hypothesis that UV-absorbing compounds and diadinoxanthin play protective roles in screening harmful radiation in red-tide dinoflagellates exposed to high-light conditions in nature is supported.
Persistence of a Photosynthetic Rhythm in Enucleated Acetabularia
The unicellular alga Acetabularia was found to show a diurnal rhythm in photosynthesis. This rhythm continued for at least three cycles in constant light and temperature, and hence can be considered…
