TL;DR: High-frequency sampling of surface picoplanktonic populations was performed in Villefranche Bay (northwestern Mediterranean Sea) during the first week of July 1996, suggesting the possibility of a common controlling factor for these populations, e.g., phosphorus or grazing.

TL;DR: The effect of a 12:12‐h light:dark (LD) cycle on the phasing of several cell parameters was explored in a variety of marine picophytoplanktonic strains and results should help to interpret diel variations in oceanic optical properties in regions where picoplankton dominates.

TL;DR: In this article, the core oscillator of the circadian clock in cyanobacteria consists of three proteins, KaiA, KaiB, KaiC, and KaiC have previously been shown to be essential for clock function.

TL;DR: TSA‐FISH with confocal microscopy with tyramide signal amplification–fluorescent in situ hybridization was combined to determine the physical association of dinoflagellate cells with bacteria and was successfully tested on natural phytoplankton assemblages, suggesting that this combination of techniques could prove a useful tool for the simultaneous identification, localization, and quantification of bacteria physically associated with dinof lagellates and more generally with phy toplankon.

TL;DR: A model of chromosome behaviour during the cell cycle using synchronized and aphidicolin-blocked cultures of the dinoflagellate Crypthecodinium cohnii to describe the successive morphological changes that chromosomes undergo during thecell cycle is summarized.
