In chromatophores from Rhodopseudomonas sphaeroides, ferricyanide induced a change in the absorption spectrum of carotenoid. The ionophore-sensitive part of the ferricyanide-induced change was similar to that induced by light or by diffusion potential. The ferricyanide-induced change is explained by the electrochromic shift of the carotenoid spectrum by the inside-positive electrical field change which is probably caused by the electrogenic electron flow from a membrane redox component to ferricyanide in the outer aqueous phase. The ionophore-insensitive part is probably the response of the carotenoid in another pool to the local field change by oxidation of bacteriochlorophyll [Okada, M. and A. Takamiya (1970) Plant 〓 Cell Physiol. 11 : 713-721].
