      abstract     = {The minor light-harvesting complexes CP24, CP26, and CP29
                      have been proposed to play a key role in the zeaxanthin
                      (Zx)-dependent high light-induced regulation (NPQ) of
                      excitation energy in higher plants. To characterize the
                      detailed roles of these minor complexes in NPQ and to
                      determine their specific quenching effects we have studied
                      the ultrafast fluorescence kinetics in knockout (ko) mutants
                      koCP26, koCP29, and the double mutant koCP24/CP26. The data
                      provide detailed insight into the quenching processes and
                      the reorganization of the Photosystem (PS) II supercomplex
                      under quenching conditions. All genotypes showed two NPQ
                      quenching sites. Quenching site Q1 is formed by a
                      light-induced functional detachment of parts of the PSII
                      supercomplex and a pronounced quenching of the detached
                      antenna parts. The antenna remaining bound to the PSII core
                      was also quenched substantially in all genotypes under NPQ
                      conditions (quenching site Q2) as compared with the
                      dark-adapted state. The latter quenching was about equally
                      strong in koCP26 and the koCP24/CP26 mutants as in the WT.
                      Q2 quenching was substantially reduced, however, in koCP29
                      mutants suggesting a key role for CP29 in the total NPQ. The
                      observed quenching effects in the knockout mutants are
                      complicated by the fact that other minor antenna complexes
                      do compensate in part for the lack of the CP24 and/or CP29
                      complexes. Their lack also causes some LHCII dissociation
                      already in the dark.},
