Cyanobacteria, or the blue-green algae as they used to be called until 1974, are the oldest
oxygenic photosynthesizers. We summarize here adventures with them since the early …

Thermoluminesence measurements are useful for the study of Photosystem II electron
transport in intact leaves, in algal and cyanobacterial cells, as well as in isolated membrane …

Photosystem II (PSII) uses the energy from red light to split water and reduce quinone, an
energy-demanding process based on chlorophyll a (Chl-a) photochemistry. Two types of …

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 …

Synechocystis sp PCC 6803 has four genes encoding flavodiiron proteins (FDPs; Flv1 to
Flv4). Here, we investigated the flv4-flv2 operon encoding the Flv4, Sll0218, and Flv2 …

Water oxidation by photosystem (PS) II in oxygenic photosynthetic organisms is a major
source of energy on the earth, leading to the production of a stable reductant. Mechanisms …

Photo-induced triplet states in the thylakoid membranes isolated from the cyanobacterium
Acaryocholoris marina, that harbours Chlorophyll (Chl) d as its main chromophore, have …

The green alga Chlamydomonas reinhardtii can photoproduce H2 gas for only a few
minutes under anaerobic conditions due to the inhibition of hydrogenase by O2 produced by …

Glutathione reductase plays a crucial role in the elimination of H 2 O 2 molecules via the
ascorbate–glutathione cycle. In this study, we used transgenic Arabidopsis plants with …

The cyanobacterium Acaryochloris marina uses chlorophyll d to carry out oxygenic
photosynthesis in environments depleted in visible and enhanced in lower-energy, far-red …
