plastoquinone/atrophy

Normal brain aging leads to decrease in cognitive functions, shrink in brain volume, loss of nerve fibers and degenerating myelin, reduction in length and branching of dendrites, partial loss of synapses, and reduction in expression of genes that play central roles in synaptic plasticity, vesicular

The putative de helix of the D1 protein is located at the acceptor side of photosystem II (PS II) and serves as an indispensable part of a niche that binds the secondary plastoquinone QB. Combinatorial mutagenesis was applied to a stretch of four residues in a highly conserved region of this

In this study, we investigated the energy dissipation processes via photosystem II and photosystem I activity in green alga Chlamydomonas reinhardtii exposed to dichromate inhibitory effect. Quantum yield of photosystem II and also photosystem I were highly decreased by dichromate effect. Such

During ripening of tomato (Lycopersicon esculentum) fruit, chloroplasts develop into chromoplasts. The chloroplast-chromoplast transition is marked by the accumulation of carotenoids and the disappearance of chlorophyll, the degradation of the highly structured thylakoid membrane system, and a
