The results to date are at the physiological level, but they have raised many questions and provided suggestions for future directions in exploring the mechanism of regulation, some of which are discussed in this perspective.
Evidence for Cyclic Electron Flow around Photosystem II in Chlorella pyrenoidosa.
The results strongly suggest that there is a cyclic electron flow around photosystem II in unpoisoned intact cells at light saturation and supraoptimal light intensities.
Changes in photosystem stoichiometry in response to environmental conditions for cell growth observed with the cyanophyte Synechocystis PCC 6714.
Three environmental stresses, CO2, Na+, and light stresses, cause changes in electron turnover capacity of PSI and Cyt c oxidase under a similar, probably a common, mechanism for monitoring redox state of thylakoid electron transport system.
Short-term and Long-term Adaptation of the Photosynthetic Apparatus: Homeostatic Properties of Thylakoids
Light-energy conversion in thylakoids is accomplished by cooperative interactions between two photoreactions. The balance between these two photoreactions determines the efficiency of energy
Study on phosphate uptake of the marine cyanophyte Synechococcus sp. NIBB 1071 in relation to oligotrophic environments in the open ocean
Results indicate that cells can grow rapidly even at phosphate concentrations as low as nanomolar levels, which suggests the involvement of a periplasmic phosphate-binding protein, analogous to that found in heterotrophic gram-negative eubacterial cells.
Regulation of nitrogen-fixation by different nitrogen sources in the marine non-heterocystous cyanobacterium Trichodesmium sp. NIBB1067
The effect of various nitrogen sources on the synthesis and activity of nitrogenase was studied in the marine, non-heterocystous cyanobacterium Trichodesmium sp. NIBB1067 grown under defined culture
On the 710 nm fluorescence emitted by the diatom Phaeodactylum tricornutum at room temperature.
Development of F(710) under red light was sensitive to cycloheximide, indicating that the development of the energy flow to F(712) requires protein synthesis and that the emitter is installed in a protein encoded in the nuclear genome like the light-harvesting complex (LHC).
