The response of sunflower to acute disturbance in water availability
Acta Agriculturae Slovenica, 2005 The influence of disturbance in water availability to electron flow in photosystem II was studied in five cultivars of sunflower. The results showed unaffected optimal quantum yield of photosystem II in the plants exposed to limited water supply ...

Molecular diversity and evolution of far-red light-acclimated photosystem I
Frontiers in Plant Science, 2023 The need to acclimate to different environmental conditions is central to the evolution of cyanobacteria. Far-red light (FRL) photoacclimation, or FaRLiP, is an acclimation mechanism that enables certain cyanobacteria to use FRL to drive photosynthesis ...

Oxidized amino acid residues in the vicinity of Q(A) and Pheo(D1) of the photosystem II reaction center: putative generation sites of reducing-side reactive oxygen species. [PDF]
PLoS ONE, 2013 Under a variety of stress conditions, Photosystem II produces reactive oxygen species on both the reducing and oxidizing sides of the photosystem. A number of different sites including the Mn4O5Ca cluster, P680, PheoD1, QA, QB and cytochrome b559 have ...

New Water Oxidation Mechanism in Photosystem II Resolves Major Experimental Controversies
Angewandte Chemie, EarlyView.In Photosystem II Oxygen Evolving Complex, we discovered the O3‐O6 peroxide at lower energy. Assignment of the O3 ligated by histidine (His337) as a slow exchanging substrate and its coupling with O6 give the O─O bond formation mechanism most consistent with all currently available experimental data. Proposal shows how protein environment can steer the

Angewandte Chemie, EarlyView.Protic molecules containing strong O─H or N─H bonds typically resist hydrogen‐atom abstraction because of the high reactivity of the resulting heteroatom‐centered radicals. However, association of the protic molecules with redox‐active Lewis acids can provide powerful hydrogen‐atom donors or proton‐coupled‐electron‐transfer reagents.
