Trivial Excitation Energy Transfer to Carotenoids is an Unlikely Mechanism for Non-Photochemical Quenching in LHCII

C. Gray, T. Wei, T. Polivka, V. Daskalakis, C. D. P. Duffy

This study challenges the idea that trivial energy transfer to carotenoid S1 states is the main mechanism of NPQ in LHCII, showing it is unlikely due to insufficient pigment movement and overestimated S1 oscillator strength.
