Inhibition of chloroplast electron transport reactions by trifluralin and diallate.
The herbicides trifluralin (alpha,alpha,alpha-trifluoro-2,6-dinitro-N, N-dipropyl-p-toluidine) and diallate (S-[2,3-dichloroallyl] diisopropylthiocarbamate) inhibit electron transport, ATP synthesis, and cytochrome f reduction by isolated spinach (Spinacia oleracea L.) chloroplasts. Both compounds inhibit noncyclic electron transport from H(2)O to ferricyanide more than 90% in coupled chloropla...
متن کاملTwo Sites of Inhibition of the Photosynthetic Electron Transport Chain by the Herbicide Trifluralin
Herbicide, Inhibition, Photosynthetic Electron Transport, Trifluralin, Thermoluminescence The effect of trifluralin on the photosynthetic electron transport has been investigated by oxygen evolution and thermoluminescence measurements. The results confirm the earlier observations that trifluralin at low concentrations blocks electron transport between the two photosystems probably at the same s...
متن کاملLocal anesthetics-induced inhibition of chloroplast electron transport.
The effects of local anesthetics on photosynthetic activity of pea chloroplasts were investigated in order to elucidate the role of Ca2+ in photosynthetic electron transport. Dibucaine, benzocaine and tetracaine were found to inhibit the O2-evolving activity. The inhibitory effect decreases in the order dibucaine greater than benzocaine greater than tetracaine greater than trimecaine similarly ...
متن کاملReversal of copper inhibition in chloroplast reactions by manganese.
In the Mehler reaction, a Hill reaction utilizing molecular oxygen as the electron acceptor, rates of net oxygen uptake are stimulated by added manganous ions. Both whole cell photosynthesis and the Mehler reaction are inhibited by copper. Copper inhibition of the Mehler reaction can be reversed by manganese salts. Glutathione. which alone has no effect on Mehler reaction rates, enhances the ef...
متن کاملInhibition of photo-induced electron transport and related reactions in isolated chloroplasts by phenol.
Phenol inhibits the Hill reaction with several Hill oxidants and the accompanying non-cyclic phosphorylation. It inhibits also pseudocyclic and cyclic phosphorylation. Partial reactions which are dependent on cyclic electron flow are inhibited too, but electron flow from ascorbate via dichlorophenolindophenol to TPN is not. The activity of various benzene and phenol derivatives was compared. It...
