Description	In these work we presented results that huge zeaxanthin formation in barley leaves treated with methyl viologen at moderate light was accompanied by an unusually slight increase in non-photochemical quenching. We demonstrated that the electron transport rate in thylakoid membranes was limited by light, implying that the lumen acidification in treated leaves was not sufficient for the formation of Z-dependent quenching centers. Our results support the view that VDE in vivo is active even at normal light conditions In these work we presented results that huge zeaxanthin formation in barley leaves treated with methyl viologen at moderate light was accompanied by an unusually slight increase in non-photochemical quenching.

Bylo ukázáno, že tato nerovnováha je způsobená limitací transportu elektronů v thylakoidní membráně. Tedy nedochází k acidifikaci lumenu v takové míře, která by byla dostačující pro vznik zhášecích center. Potvrdili jsme hypotézu, že enzym VDE je in vivo aktivní i za nižších intenzit světla, při slabé acidifikaci lumenu (cs)
