The chlorophylls are a structurally and functionally distinct group of macrocyclic tetrapyrrole
pigments that may occur at the porphyrin, chlorin or bacteriochlorin oxidation levels …

Chlorophylls are magnesium-tetrapyrrole molecules that play essential roles in
photosynthesis. All chlorophylls have similar five-membered ring structures, with variations …

Photosystem II (PSII) is a multisubunit pigment–protein complex that uses light-induced
charge separation to power oxygenic photosynthesis. Its reaction center chromophores …

Why do plants reflect in the green and have a “red edge” in the red, and should extrasolar
photosynthesis be the same? We provide (1) a brief review of how photosynthesis works,(2) …

As photosynthesis on Earth produces the primary signatures of life that can be detected
astronomically at the global scale, a strong focus of the search for extrasolar life will be …

Both chlorophyll f and chlorophyll d are red-shifted chlorophylls in oxygenic photosynthetic
organisms, which extend photon absorbance into the near infrared region. This expands the …

Abstract A blue diode PAM (P ulse A mplitude M odulation) fluorometer was used to
measure rapid Photosynthesis (P) versus Irradiance (E) curves (P vs. E curves) in …

If you were asked to speculate about the form extra-terrestrial life on Mars might take, which
geomicrobial phenomenon might you select as a model system, assuming that life on Mars …

The composition of photosystem II (PSII) in the chlorophyll (Chl) d-dominated
cyanobacterium Acaryochloris marina MBIC 11017 was investigated to enhance the general …

The proliferation of phototrophy within early-branching prokaryotes represented a significant
step forward in metabolic evolution. All available evidence supports the hypothesis that the …
