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 ...

Comparison of drought stress response and gene expression between a GM maize variety and a near-isogenic non-GM variety [PDF]
, 2015 Maize MON810, grown and commercialised worldwide, is the only cultivated GM event in the EU. Maize MON810, variety DKC6575, and the corresponding near-isogenic line Tietar were studied in different growth conditions, to compare their behaviour in ...

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

A mechanistic study on the phototoxicity of atorvastatin: singlet oxygen generation by a phenanthrene-like photoproduct [PDF]
, 2009 Atorvastatin calcium (ATV) is one of the most frequently prescribed drugs worldwide. Among the adverse effects observed for this lipid-lowering agent, clinical cases of cutaneous adverse reactions have been reported and associated with photosensitivity ...

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.

IOP Conference Series: Earth and Environmental Science, 2022 Abstract The influence of anthropogenic discharges on the environment is an increasing concern among environmental toxicologists. This investigation set out to analyse the impacts of selected herbicides; diuron, terbuthylazine and isoproturon on two strains of Ectocarpus siliculosus with different pollution histories, LIA4 and Es524 ...

Rethinking the Influence of Chloroplast Movements on Non-photochemical Quenching and Photoprotection [PDF]
Plant Physiology, 2020 Under blue light, plant chloroplasts relocate to different areas of the cell. The photoreceptor phototropin2 (phot2) mediates the chloroplast movement mechanism under excess blue light alongside the chloroplast unusual positioning1 (chup1) protein. Recently, it has been proposed that leaf transmittance changes associated with chloroplast relocation ...
