Zeaxanthins 136-146 Chlorophyll A-B binding family protein Arabidopsis thaliana 44-48 21474447-5 2011 The qE in chloroplasts lacking PsbS significantly quenched the level of fluorescence when all PSII reaction centers were in the open state (F(o) state), protected PSII reaction centers from photoinhibition, was modulated by zeaxanthin and was accompanied by the qE-typical absorption spectral changes, known as DeltaA(535). Zeaxanthins 224-234 Chlorophyll A-B binding family protein Arabidopsis thaliana 31-35 21340700-6 2011 Overexpression of PsbS was found to increase the rate of NPQ formation, as previously reported for zeaxanthin. Zeaxanthins 99-109 Chlorophyll A-B binding family protein Arabidopsis thaliana 18-22 20442929-0 2010 PsbS-specific zeaxanthin-independent changes in fluorescence emission spectrum as a signature of energy-dependent non-photochemical quenching in higher plants. Zeaxanthins 14-24 Chlorophyll A-B binding family protein Arabidopsis thaliana 0-4 16545380-3 2006 It is suggested that PsbS alone can cause the quenching, supporting the model in which zeaxanthin acts as an allosteric activator and is not the primary cause of the process.
