TL;DR: Initial molecular analyses reveal that targeted downregulation likely occurs through transcriptional and post-transcriptional gene silencing mechanisms, and molecular players involved in RNA silencing in other eukaryotes are only poorly conserved in diatoms.

TL;DR: It is shown that two marine diatom species, Phaeodactylum tricornutum and Thalassiosira pseudonana, possess a bona fide red/far-red light sensing phytochrome (DPH) that uses biliverdin as a chromophore and displays accentuated red-shifted absorbance peaks compared with other characterized plant and algal phy tochromes.

TL;DR: Results seem to suggest a possible allelopathic activity of caulerpenyne, which may play a role in the successful competition of the invasive C. racemosa var.

TL;DR: The high capacity of this alga to reorganise its photosynthetic apparatus in relation to the available light under the canopy of a Cymodocea nodosa meadow was demonstrated.

TL;DR: In the shallowest plants, the lack of a midday depression in both the maximum relative ETRs and the photosynthetic efficiency at sub-saturating irradiance pointed to a maintenance of energy conversion levels despite the protective lowering of light-harvesting efficiency revealed by the trend in Fv/Fm.
