Photosynthetic Quantum Yield Dynamics: From Photosystems to Leaves
Sander W. Hogewoning,Emilie Wientjes,Emilie Wientjes,Peter Douwstra,G. Trouwborst,Wim van Ieperen,Roberta Croce,Roberta Croce,Jeremy Harbinson +8 more
TL;DR: It is shown quantitatively that leaves acclimate their photosystem composition to their growth light spectrum and how this changes the wavelength dependence of the photosystem excitation balance and quantum yield for CO2 fixation, and it is proved that combining different wavelengths can enhance quantum yields substantially.
High-light vs. low-light: Effect of light acclimation on photosystem II composition and organization in Arabidopsis thaliana
TL;DR: Biochemical and structural analysis of isolated thylakoid membranes by electron microscopy indicates a distinctly different response at the level of PSII and LHCII upon plant acclimation.

LHCII is an antenna of both photosystems after long-term acclimation.
TL;DR: It is demonstrated that in most natural light conditions LHCII serves as an antenna of both Photosystem I and Photosystem II and it is quantitatively demonstrated that this is required to achieve excitation balance between the two photosystems.

Singlet Energy Dissipation in the Photosystem II Light‐Harvesting Complex Does Not Involve Energy Transfer to Carotenoids
TL;DR: It is proposed that a chlorophyll-chlorophyll charge-transfer state is formed in LHC II oligomers which is an intermediate in the quenching process, and the relevance to non-photochemical quench in vivo is discussed.
Strong antenna-enhanced fluorescence of a single light-harvesting complex shows photon antibunching
TL;DR: An over 500-fold fluorescence enhancement of light-harvesting complex 2 (LH2) at the single-molecule level by coupling to a gold nanoantenna by exploiting the unique brightness of the resonant antenna.
