Evidence for a Plastic Dual Circadian Rhythm in the Oyster Crassostrea gigas
TL;DR: The present work demonstrates the presence of a circadian rhythm in the oyster Crassostrea gigas and describes it as a dual organism that was nocturnal in autumn–winter and diurnal in spring–summer, a significant advantage in terms of adaptability in a highly changing environment.
Genetic and genotoxic impacts in the oyster Crassostrea gigas exposed to the harmful alga Alexandrium minutum.
TL;DR: Results indicate genotoxic effects and gene repression in C. gigas following behavioral disturbance by A. minutum, and both the PCR product profile and the number of hybridization sites for the RAPD probe OPB7 were modified.

TL;DR: It is revealed that tidal cycles predominate in the transcriptome and physiology of mussels fixed directly at hydrothermal vents at 1,688 m depth at the Mid-Atlantic Ridge, whereas daily cycles prevail in mussels sampled after laboratory acclimation.
The toxic dinoflagellate Alexandrium minutum disrupts daily rhythmic activities at gene transcription, physiological and behavioral levels in the oyster Crassostrea gigas.

TL;DR: The results show that a realistic bloom of A. minutum clearly can disrupt numerous and diverse molecular, physiological and behavioral functions via a loss of rhythmicity.

Oyster transcriptome response to Alexandrium exposure is related to saxitoxin load and characterized by disrupted digestion, energy balance, and calcium and sodium signaling.

TL;DR: This paper explored the transcriptome of the digestive gland of the Pacific oyster Crassostrea gigas fed experimentally with a toxic Alexandrium minutum culture and found that the largest differences in transcript abundance were between oysters with contrasting toxin loads (1098 transcripts), rather than between exposed and non-exposed oysters (16 transcripts).
