A characteristic feature of the reaction center (RC) of the filamentous phototrophic bacterium Chloroflexus (Cfl.) aurantiacus is the presence of а bacteriopheophytin molecule (BPheo; H) at the ϕB binding site, corresponding to the bacter...
The contribution of the 240Ala:Glu:Glu:Thr243 sequence in the DE-loop of D2 to the acceptor side of Photosystem II [0.03%]

The D2 protein of Photosystem II has five transmembrane helices (A-E). An extended loop, connecting helices D and E, contributes to the binding environments of the primary quinone electron acceptor QA, and that of the bicarbonate bound to t...
Quick conversions and de novo synthesis within the entire α- and β-carotenoid branches during non-steady-state light transients [0.03%]

Understanding the rapid adjustments of plants to high-light exposure remains challenging, as multiple excitation and de-excitation pathways are simultaneously activated. In this study, we examined carotenoid pigment conversions at the secon...

In photosystem II (PSII) chlorophyll (Chl) fluorescence yield (F) rises during low-to-high light induction. Based on a critical review of the literature, the following evidence is summarized. (1) As the primary acceptor quinone QA gets redu...
Extracellular electron transfer by the cultured coral photosymbiont Symbiodinium microadriaticum [0.03%]

Photosynthetic microorganisms may show extracellular electron transfer (EET), in which some of the electrons generated by photosynthesis or respiration are lost from the cell. Most studies have focussed on cyanobacteria, with very few on eu...
Exciton structure of LHCII antenna revisited: complex time-dependent Redfield approach [0.03%]

We develop the exciton model of the major light-harvesting complex LHCII from higher plants based on complex time-dependent Redfield (ctR) theory. A simultaneous quantitative fit of the absorption, linear dichroism, and fluorescence spectra...
Tuning the F695 fluorescent state in photosystem II using site-directed mutagenesis in Synechocystis sp. PCC 6803 [0.03%]

Amala Phadkule et al.
In photosynthetic proteins, pigments at a higher energy level funnel excitation energy to pigments at a lower energy level. Specifically, in Photosystem II (PSII), energy is transferred downhill to the reaction center (RC), where water spli...
The rate of photosynthetic induction across different light intensities can be approximated using the light response curve of photosynthesis [0.03%]
利用光响应曲线逼近不同光照强度下的光合诱导速率

Elias Kaiser et al.
While natural light in plant canopies often fluctuates and shows a large range of possible intensities, the rate of photosynthetic induction is often measured at only two light intensities. This prompts the question as to how the relationsh...
