Non-photochemical quenching (NPQ) of chlorophyll fluorescence is thought to be an
indicator of an essential regulation and photoprotection mechanism against high-light stress …

The heterologous expression of the far-red absorbing chlorophyll (Chl) f in organisms that
do not synthesize this pigment has been suggested as a viable solution to expand the solar …

We establish a general kinetic scheme for energy transfer and trapping in the photosystem I
(PSI) of cyanobacteria grown under white light (WL) or far-red light (FRL) conditions. With …

Until now, the functional and structural characterization of monomeric photosystem 1 (PS1)
complexes from Thermosynechococcus elongatus has been hampered by the lack of a fully …

The recent discovery of extremely red-shifted chlorophyll f pigments in both photosystem I
(PSI) and photosystem II has led to the conclusion that chlorophyll f plays a role not only in …

Abstract Photosystem I (PSI) from Chroococcidiopsis thermalis PCC 7203 grown under far-
red light (FRL;> 725 nm) contains both chlorophyll a and a small proportion of chlorophyll f …

Time-resolved fluorescence studies with a 3-ps temporal resolution were performed in order
to:(1) test the recent model of the reversible primary charge separation in Photosystem I …

Non-photochemical quenching (NPQ) protects photosynthetic organisms against
photodamage by high light. One of the key measuring parameters for characterizing NPQ is …

The highly efficient desiccation-induced quenching in the poikilohydric lichen Parmelia
sulcata has been studied by ultrafast fluorescence spectroscopy at room temperature (rt) …

Photosystem I is one of the key players in the conversion of solar energy into chemical
energy. While the chlorophyll dimer P700 has long been identified as the primary electron …
