The Peculiar Features of Non-Photochemical Fluorescence Quenching in Diatoms and Brown Algae

Finally, a last phase in the calcareous nanno- plankton evolution started in the Eocene (Figs. 2, S3) with smoothed NAR steadily high or slightly increasing (Figs. 2, S1) but

In Diatoms, the Transthylakoid Proton Gradient Regulates the Photoprotective Non-photochemical Fluorescence Quenching Beyond its Control on the Xantho- phyll Cycle...

The major known differences concern the following processes: (1) pigment biosynthesis, (2) light- harvesting organisation, (3) mechanism of photoprotection, (4)

Table 1: Pigment composition of dark-adapted CL and IL cells grown under an intensity of 40 µmol photons.m -2 .s -1 , and of corresponding sucrose gradient fractions

During an illumination at 2000 µmol photons.m -2 .s -1 , the variation in the relative concentration of active PSII reaction centers was determined, as a function of the duration of

We could recover information for a maximum of 77 species, representative of most orders of brown algae (Supplemental Dataset 1). We estimated ancestral states for
