Inhibition of photosynthetic carbon dioxide fixation in isolated spinach chloroplasts exposed to reduced osmotic potentials.
Reduced osmotic potentials inhibited the rate of CO(2) fixation by isolated intact spinach (Spinacia oleracea) chloroplasts. This inhibition was observed immediately after transfer of chloroplasts from a solution containing 0.33 m sorbitol to higher sorbitol concentrations, and the depressed rate remained constant. The inhibited CO(2) fixation could not be attributed to a decreased rate of phot...
متن کاملPhotosynthesis by isolated chloroplasts. Inhibition by DL-glyceraldehyde of carbon dioxide assimilation.
Photosynthetic carbon assimilation and associated CO(2)-dependent O(2) evolution by chloroplasts isolated from pea shoots and spinach leaves is almost completely inhibited by 10mm-dl-glyceraldehyde. The inhibitor is without appreciable effect on photosynthetic electron transport, photophosphorylation, the carboxylation of ribulose 1,5-diphosphate or the reduction of 3-phosphoglycerate, but appa...
متن کاملEffects of disalicylidenepropanediamines on photosynthetic electron transport of isolated spinach chloroplasts.
The effects of disalicylidenepropanediamine (DSPD) and disulfo-disalicylidenepropanediamine (sulfo-DSPD) on the photosynthetic electron transport of isolated chloroplasts have been reexamined.Our data suggest that DSPD, but not sulfo-DSPD, is an effective inhibitor of electron transport between photosystem II and photosystem I before or at plastocyanin. Furthermore, both DSPD and sulfo-DSPD blo...
متن کاملThe cupric ion as an inhibitor of photosynthetic electron transport in isolated chloroplasts.
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. Binding of Cu(2+) to the chloroplast membranes resulted in removal of Cu(2+) from sol...
متن کاملMode of Inhibition of Photosynthetic Electron Transport by Substituted Diphenylethers
Herbicides, Photosynthesis, Diphenylether, Inhibitors, Plastoquinone Several substituted diphenylethers were found to be effective inhibitors of photosynthetic electron flow in isolated thylakoid membranes from spinach chloroplasts. Their site of inhibition was localized with artificial acceptor and donor systems. The phenylether of an alkyl substituted nitrophenol is primarely inhibiting elect...
