Gradients of photoinhibition within a leaf caused by different color lights were studied to get more insight into the controversy whether photon absorption by chlorophyll or Mn is the primary cause of photoinhibition, suggested by the excess-energy hypothesis or the Mn (two-step) hypothesis, respectively. We photoinhibited lincomycin-treated leaf-discs

State Transition and Photoinhibition
2006Optimal utilization of absorbed light energy and avoidance of oxidative damage induced by excessive excitation (photoinhibition) constitute a major problem for photosynthetic oxygen evolving cells. Adaptation to transient changes in light absorption and energy utilization is achieved by regulation of photochemistry, and both radiative and nonradiative ...

Photoinhibition of photosynthesis in the cyanobacterium Microcystis aeruginosa
Planta, 1983We have examined characteristics of the photoinhibition of photosynthesis which occur in the unicellular cyanobacterium Microcystis aeruginosa, following exposure to photon fluence rates in excess of those required for growth. Photoinhibition occurs following exposure of cells to a photon fluence rate of 1,000 μmol m(-2) s(-1), which is manifested as a

Photoinhibition of Photosynthetic Bacteria
1990Photoinhibition of higher plants encompasses a range of phenomena, many of which stem from the requirement to harmlessly dissipate excess light energy. These responses to light stress are manifest as a decrease in the quantum yield of photosynthesis and a quenching of chl fluorescence and primarily affect PS II.

Photoinhibition of the Photosynthesis
2009(Fotoinibição da Fotossíntese). A vida na terra depende da energia derivada do sol. A fotossíntese é o único processo de importância biológica que pode colher esta energia. O termo “fotossíntese” significa “síntese que usa luz”, literalmente. Organismos fotossintéticos usam energia solar para sintetizar combinações orgânicas que não podem ser formadas ...

Regulation of CO2 Assimilation During Photoinhibition
1990At high irradiance photosynthesis is limited by CO2 assimilation and more light is absorbed than can be effectively used to drive photosynthesis. Dissipation of surplus excitation energy is essential because excessive excitation leads to the light-induced loss of thylakoid efficiency called photoinhibition.
