【 摘 要 】

It is shown that electron-transport elements of the photosynthetic chain located between plastoquinone and photosystem I centers are not involved in oxidation of plastoquinone in the chlororespiratory pathway. The ionophore dicyclohexyl-18-crown-6 is shown to induce a reduction of the plastoquinone pool in the dark. This is interpreted as indicating the existence of a coupling site in the chlororespiratory pathway between NAD(P)H and plastoquinone.
