      abstract     = {We report on the changes the photosynthetic apparatus of
                      Chlamydomonas reinhardtii undergoes upon acclimation to
                      different light intensity. When grown in high light, cells
                      had a faster growth rate and higher biomass production
                      compared with low and control light conditions. However,
                      cells acclimated to low light intensity are indeed able to
                      produce more biomass per photon available as compared with
                      high light-acclimated cells, which dissipate as heat a large
                      part of light absorbed, thus reducing their photosynthetic
                      efficiency. This dissipative state is strictly dependent on
                      the accumulation of LhcSR3, a protein related to
                      light-harvesting complexes, responsible for nonphotochemical
                      quenching in microalgae. Other changes induced in the
                      composition of the photosynthetic apparatus upon high light
                      acclimation consist of an increase of carotenoid content on
                      a chlorophyll basis, particularly zeaxanthin, and a major
                      down-regulation of light absorption capacity by decreasing
                      the chlorophyll content per cell. Surprisingly, the antenna
                      size of both photosystem I and II is not modulated by
                      acclimation; rather, the regulation affects the PSI/PSII
                      ratio. Major effects of the acclimation to low light consist
                      of increased activity of state 1 and 2 transitions and
                      increased contributions of cyclic electron flow.},
