DOI: 10.1002/2017jc012747
Abstract: Southern Ocean phytoplankton assemblages acclimated to low-light environments that result from deep mixing are often sensitive to ultraviolet and high photosynthetically available radiation. In such assemblages, exposures to inhibitory irradiance near the surface result in… read more here.

Effects of low temperature on photoinhibition and singlet oxygen production in four natural accessions of Arabidopsis
Sign Up to like & getrecommendations! Published in 2020 at "Planta"
DOI: 10.1007/s00425-020-03423-0
Abstract: Low temperature decreases PSII damage in vivo, confirming earlier in vitro results. Susceptibility to photoinhibition differs among Arabidopsis accessions and moderately decreases after 2-week cold-treatment. Flavonols may alleviate photoinhibition. The rate of light-induced inactivation of… read more here.

DOI: 10.1016/j.jtbi.2021.110580
Abstract: Oxygenic photoautotrophs are, paradoxically, subject to photoinhibition of their photosynthetic apparatus, in particular one of its major components, the Photosystem II (PSII). This photoinhibition is generalized across species, light conditions and habitats, imposing substantial metabolic… read more here.

DOI: 10.1038/s41598-018-24711-6
Abstract: A clear-cutting of canopy trees during winter often causes severe foliar damage during the following spring in forest floor seedlings of Abies sachalinensis, a typical shade-tolerant evergreen coniferous species. The maximum photochemical efficiency of photosystem… read more here.

DOI: 10.3390/antiox11122325
Abstract: Fluctuating light (FL) can cause the selective photoinhibition of photosystem I (PSI) in angiosperms. In nature, leaves usually experience FL conditions with the same low light and different high light intensities, but the effects of… read more here.
