Red and blue light cues drive contrasting remodeling of lipophilic metabolites and photophysiology in natural benthic diatom biofilms

Alexandre Desparmet, Johann Lavaud, Bruno Jesus, Antoine Medico, Cédric Hubas

Within 30 minutes, red light remodeled natural benthic diatom lipids and pigments more than blue; blue high light most altered photophysiology; de-epoxidation was similar at equal incident intensity.

The peculiar photobiology of a giant motile diatom inhabiting the subtidal sediments of the bay of Brest.

Anna Isaia, Gaspard Delebecq, Pauline Breton, Philippe Rosa, Vona Méléder, Aude Leynaert, Johann Lavaud

This study examines the light-dependent responses of the subtidal giant diatom Pleurosigma strigosum, revealing its adaptation to low green-blue light conditions and its ecological success in subtidal sediments.
