A mechanistic model of photoinhibition [PDF]
New Phytologist, 2000 A mechanistic model was developed, to simulate the main facets of photoinhibition in phytoplankton. Photoinhibition is modelled as a time dependent decrease in the initial slope of a photosynthesis versus irradiance curve, related to D1 (photosystem II reaction centre protein) damage and non‐photochemical quenching.

Photoinhibition of Photosystem II
International Review of Cell and Molecular Biology, 2013Photoinhibition of Photosystem II (PSII) is the light-induced loss of PSII electron-transfer activity. Although photoinhibition has been studied for a long time, there is no consensus about its mechanism. On one hand, production of singlet oxygen ((1)O(2)) by PSII has promoted models in which this reactive oxygen species (ROS) is considered to act as ...

Dynamics of Phytoplankton Communities Under Photoinhibition
Bulletin of Mathematical Biology, 2013We analyzed a model of phytoplankton competition for light in a well-mixed water column. The model, proposed by Gerla et al. (Oikos 120:519-527, 2011), assumed inhibition of photosynthesis at high irradiance (photoinhibition). We described the global behavior through mathematical analyses, providing a general solution to the multi-species competition ...

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.

When photosynthetic organisms are exposed to higher irradiances which exceed their light energy requirement for photosynthetically operated metabolisms, a reduction of photosynthetic capacity, called photoinhibition, occurs [1, 2, 3]. Under excessive light conditions Ohad et al. [4] and Mattoo et al.

Does Ozone Exposure Protect from Photoinhibition?
Free Radical Research, 1999Tropospheric ozone and high light intensities are two stress factors that often occur simultaneously under natural conditions. Ozone is well known to form oxygen radicals in the apoplastic water and long lasting photoinhibition can cause photooxidative damage also by formation of several species of oxygen radicals.

Formate protects photosynthetic machinery from photoinhibition
Journal of Bioscience and Bioengineering, 2000In plants, environmental adversity often leads to the formation of reactive oxygen species (ROS) because of excess light energy. We found that incubation of rice leaves under high light intensity together with CO2-depleted air seriously damaged photosynthesis; however, the application of potassium formate (2 mM) before the photoinhibitory treatment ...
