The origin and early evolution of photosynthesis are reviewed from an ecophysiological
perspective. Earth's first ecosystems were chemotrophic, fueled by geological H2 at …

Natural edible pigments, high safety and low toxicity, usually possess various nutritional and
pharmacological effects, and they have huge practical application value in the market …

Photosynthesis is a complex metabolic process enabling photosynthetic organisms to use
solar energy for the reduction of carbon dioxide into biomass. This ancient pathway has …

The phytochrome superfamily comprises three groups of photoreceptors sharing a
conserved GAF (cGMP-specific phosphodiesterases, cyanobacterial adenylate cyclases …

Chlorophylls are vital for photosynthesis, allowing plants to absorb energy from light for
photosynthesis. More than one hundred species of chlorophyll have been identified. Among …

Photosynthetic reaction centers (RCs) are membrane proteins converting photonic
excitations into electric gradients. The heliobacterial RCs (HbRCs) are assumed to be the …

Recent studies show that triclosan (TCS) exposure causes reduction in pigments,
suppression of photosynthesis, and induction of oxidative stress at the physiological level …

Anoxygenic photosynthesis is diversified into two classes: chlorophototrophy based on a
bacterial type-I or type-II reaction center (RC). Whereas the type-I RC contains both …

Green bacteria include chlorophototrophic members of the phyla Chlorobi, Chloroflexi, and
Acidobacteria and are defined by their use of chlorosomes for light-harvesting. Despite their …

Photosynthetically active chlorophyll molecules are biosynthesized from 5-aminolevulinic
acid through protoporphyrin IX. The multistep enzymatic transformations were well …
