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 Workplace Institute of Microbiology Contact Eliška Spurná, eliska.spurna@biomed.cas.cz, Tel.: 241 062 231 Year of Publishing 2009
