Photoinhibition at Chilling Temperatures
Australian Journal of Plant Physiology, 1988Relative susceptibilities of chilled leaves to photoinhibition were determined for 15 species of crop annuals showing a wide range of chilling tolerance. Leaf tissue at 7°C was exposed to a moderate photon irradiance of 300 µmol m-2 s-1 and photoinhibition was measured by the decrease in chlorophyll fluorescence (Fv/Fm) measured at 77K.

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

History of photoinhibition research
1993At the beginning of our century few scientists paid attention to the phenomenon of inactivation of photosynthesis by high light intensities which was later called photoinhibition. In the period 1925-1950, the idea was established that photoinhibition is a reversible inactivation, determined by light intensity and exposure time, followed by irreversible

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.

Cyanophage infection and photoinhibition in marine cyanobacteria
Research in Microbiology, 2004Members of two cyanobacterial genera, Synechococcus and Prochlorococcus, are dominant within the prokaryotic component of the picophytoplankton and contribute significantly to global photosynthetic productivity. These organisms are known to be susceptible to infection by bacteriophages (viruses that infect bacteria) and it is believed that phage ...

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.
