Plants and cyanobacteria use the chlorophylls embedded in their photosystems to absorb
photons and perform charge separation, the first step of converting solar energy to chemical …

Photosystems I and II convert solar energy into the chemical energy that powers life.
Chlorophyll a photochemistry, using red light (680 to 700 nm), is near universal and is …

A limiting factor for photosynthetic organisms is their light-harvesting efficiency, that is the
efficiency of their conversion of light energy to chemical energy. Small modifications or …

Cyanobacteria carry out photosynthetic light-energy conversion using phycobiliproteins for
light harvesting and the chlorophyll-rich photosystems for photochemistry. While most …

Photosystem I (PSI) converts photons into electrons with a nearly 100% quantum efficiency.
Its minimal energy requirement for photochemistry corresponds to a 700-nm photon …

Chlorophyll d and chlorophyll f are red-shifted chlorophylls, because their Qy absorption
bands are significantly red-shifted compared with chlorophyll a. The red-shifted chlorophylls …

Phototrophic organisms are superbly adapted to different light environments but often must
acclimate to challenging competition for visible light wavelengths in their niches. Some …

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 …

Oxygenic photosynthesis has historically been considered limited to be driven by the
wavelengths of visible light. However, in the last few decades, various adaptations have …

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 …
