On the origin of a slowly reversible fluorescence decay component in the Arabidopsis npq4 mutant.

Philosophical transactions of the Royal Society of London. Series B, Biological sciences - 19 Apr 2014

Abstract excerpt

Over-excitation of photosynthetic apparatus causing photoinhibition is counteracted by non-photochemical quenching (NPQ) of chlorophyll fluorescence, dissipating excess absorbed energy into heat. The PsbS protein plays a key role in this process, thus making the PsbS-less npq4 mutant unable to carry out qE, the major and most rapid component of NPQ. It was proposed that npq4 does perform qE-type quenching,...
