A Commonly Used Photosynthetic Inhibitor Fails to Block Electron Flow to Photosystem I in Intact Systems [PDF]
Frontiers in Plant Science, 2020 In plant science, 2,4-dinitrophenylether of iodonitrothymol (DNP-INT) is frequently used as an alternative to 2,5-dibromo-6-isopropyl-3-methyl-1,4-benzoquinone (DBMIB) to examine the capacity of plastoquinol and semiquinone to reduce O-2.

The Cupric Ion as an Inhibitor of Photosynthetic Electron Transport in Isolated Chloroplasts [PDF]
Plant Physiology, 1972 Strong inhibition of uncoupled photosynthetic electron transport by Cu(2+) in isolated spinach chloroplasts was observed by measuring changes in O(2) concentration in the reaction medium. Inhibition was dependent not only on the concentration of the inhibitor, but also on the ratio of chlorophyll to inhibitor.

On a new inhibitor of photosynthetic electron-transport in isolated chloroplasts
Zeitschrift Fur Naturforschung - Section B Journal of Chemical Sciences, 1970 A halogenated benzoquinone has been found to inhibit the photosynthetic electron transport system in isolated chloroplasts. 2·10-6ᴍ of dibromo-thymoquinone inhibit the Hill- reaction with NADP, methylviologen or anthraquinone to 100%, but do not effect the photoreduction of NADP at the expense of an artificial electron donor.

Inhibitor studies on the photosynthetic carbon reduction cycle in Chlorella pyrenoidosa [PDF]
Biochimica Et Biophysica Acta (BBA) - Biophysics Including Photosynthesis, 1965 Abstract Transient changes in the levels of intermediates of the photosynthetic carbon reduction cycle induced by the addition of various chemical compounds to Chlorella pyrenoidosa photosynthesizing under steady-state conditions have been studied. Vitamin K 5 , hexylresorcinol, 3-(3,4-dichlorophenyl)-2,1-dimethylurea and m -chlorocarbonyl cyanide

Inhibition of the Formation of Photosynthetic Enzymes by Inhibitors of Photosynthesis [PDF]
Plant Physiology, 1968 It has been shown previously that an increase in ribulose diphosphate carboxylase activity occurs upon brief illumination of leaves of dark-grown Zea mays plants; an increase in ribose 5-phosphate isomerase occurs after prolonged illumination.

Formate as an Inhibitor of Photosynthetic Electron Flow
Zeitschrift für Naturforschung C, 1984 The effects of formate on the Hill reaction in isolated broken pea chloroplasts were investigated. Addition of formate to chloroplasts has two distinct effects: I. basal electron flow can be stimulated 3-fold; 2. uncoupled electron flow is inhibited. The stimulating effect is due to uncoupling by formate and appears instantaneous.

Picrate as an Inhibitor of Photosystem II in Photosynthetic Electron Transport [PDF]
European Journal of Biochemistry, 1982 2,4,6‐Trinitrophenol (picric acid) is an effective inhibitor of photosynthetic electron transport (pI50 value 6.82). By means of artificial donor and acceptor systems its site of inhibition was located at the reducing side of photo‐system II. In addition, picric acid also uncouples photophosphorylation but a much higher concentration is required than ...

Altered Rubisco activity and amounts of a daytime tight-binding inhibitor in transgenic tobacco expressing limiting amounts of phosphoribulokinase [PDF]
, 1996 Transgenic tobacco with RuBP-limited photosynthetic assimilation due to a 95% reduction in phosphoribulokinase activity, had higher specific activities of Rubisco in fresh extracts and after full activation, than in the wild type.

Hydrostatic Pressure: A Reversible Inhibitor of Primary Photosynthetic Processes
Zeitschrift für Naturforschung C, 1973 Abstract Primary photosynthetic processes under pressures of up to 1300 atm were studied by means of chlorophyll fluorescence induction (Kautsky-effect) and compared to simultaneous oxygen exchange transients determined polarographically. Chlorophyll fluorescence induction was affected by increased hydrostatic pressure in three distinct
