Frontiers in Marine Science, 2018 Light availability is considered a key factor regulating the thermal sensitivity of reef building corals, where excessive excitation of photosystem II (PSII) further exacerbates pressure on photochemical pathways already compromised by heat stress. Coral

Changes in Chlorophyll a fluorescence and DNA as a plant response to UV-B radiation in Gnaphalium vira-vira [PDF]
Polish Polar Research, 2022 Ozone depletion at southern latitudes has recently increased the fluence of ultraviolet-B (UV-B) radiation striking the ground. This phenomenon has sparked much interest in unravelling the effects of this harmful radiation on living systems.

Alteration of photosystem II properties with non-photochemical excitation quenching [PDF]
Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2000 Oxygen yield from single turnover flashes and multiple turnover pulses was measured in sunflower leaves differently pre–illuminated to induce either ‘energy–dependent type’ non–photochemical excitation quenching ( q E ) or reversible, inhibitory type non–photochemical quenching ( q

Site, trigger, quenching mechanism and recovery of non-photochemical quenching in cyanobacteria: recent updates [PDF]
Photosynthesis Research, 2018 Cyanobacteria exhibit a novel form of non-photochemical quenching (NPQ) at the level of the phycobilisome. NPQ is a process that protects photosystem II (PSII) from possible highlight-induced photo-damage. Although significant advancement has been made in understanding the NPQ, there are still some missing details.

Photochemistry in Terrestrial Exoplanet Atmospheres III: Photochemistry and Thermochemistry in Thick Atmospheres on Super Earths and Mini Neptunes [PDF]
, 2013 Some super Earths and mini Neptunes will likely have thick atmospheres that are not H2-dominated. We have developed a photochemistry-thermochemistry kinetic-transport model for exploring the compositions of thick atmospheres on super Earths and mini ...

Photosynthesis sensitivity to NH4+-N change with nitrogen fertilizer type
Plant, Soil and Environment, 2014 N-fertilization type affected differently tomato growth. In the field experiment, hydroponic cultures were conducted using NO3-N (5 mmol); mixture of KNO3-N (3 mmol) and (NH4)2SO4-N (2 mmol); NH4+-N (5 mmol) or urea (5 mmol) as nitrogen source.

Radical Fluoroalkylation Reactions [PDF]
, 2018 Recent protocols and reactions for catalytic radical perfluoroalkylations will be described. The production of perfluoroalkyl radicals (RF = CnF2n+1, n ≥ 2), which effect both addition and substitution reactions on organic substrates, can be realized ...
