The Inhibition of Photosynthetic Electron Flow in Chloroplasts by the Dinitrophenylether of Bromo- or Iodo-nitrothymol
نویسندگان
چکیده
The O-dinitrophenyl derivatives of 2 -bromoand 2-iodo-4-nitrothymol are inhibitors of photo synthetic electron flow from water to NADP or methylviologen, yielding 50% inhibition at 0.5 /x m . Photoreductions by either photosystem I or photosystem II alone are not inhibited. The inhibition site is bypassed by TMPD. The inhibition pattern identical to the one of dibromothymoquinone. It is reduction of plastoquinone.

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...

Dibromothymoquinone inhibits photosynthetic NADP reduction by broken chloroplasts. The inhibition of electron flow and coupled ATP formation is effectively reversed by the addition of thiol compounds.

Alkyl substituted 2-halogen-4-nitro-phenols (like bromonitrothymol) are potent inhibitors of photosynthetic electron flow in chloroplasts. There inhibition site is identical to that of DCMU, though the phenols do not contain their essential chemical element responsible for inhibition nor do they follow their correlation of chemical structure and biochemical function. Binding of labelled metribu...
متن کاملComparison of the Inhibition of Photosynthetic Reactions in Chloroplasts by Dibromothymoquinone, Bromonitrothymol and Ioxynil
The inhibition of photosynthetic electron flow in broken chloroplasts by dibromothymoquinone and dibromothymohydroquinone (DBMIBH2) is reversed by dithiothreitol (DTT) as well as by serum albumin. The reversal of DBMIBH2 inhibition by DTT shows a time lag, that of DBMIB only, when chloroplasts and DBMIB had been preilluminated. This is to show that chloroplasts reduce DBMIB and that probably DB...
متن کاملReevaluation of the role of bicarbonate and formate in the regulation of photosynthetic electron flow in broken chloroplasts.
The stimulation of the Hill reaction in CO(2)-depleted broken chloroplasts (Pisum sativum L. cv Rondo) by the total amount of dissolved CO(2) and HCO(3) (-) (bicarbonate(*)) was measured at several formate concentrations. Formate appears to be a competitive inhibitor of the bicarbonate(*) stimulation of electron flow. From these experiments we have obtained a reactivation constant (K(r)) of 78 ...
