Short-term salt stress strongly affects dynamic photosynthesis, but not steady-state photosynthesis, in tomato (Solanum lycopersicum)

Environmental and Experimental Botany, 2018
Abstract Salt stress occurs worldwide due to widespread soil salinization. Also, plants are often subjected to rapidly alternating periods of sun and shade (sunflecks). Despite this combined occurrence of salt stress and sunflecks, dynamic photosynthetic responses to sunflecks under salt stress remain unknown. This study addresses this discrepancy by

Relationship of steady-state photosynthesis to fluorescence in eucaryotic algae

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1986
Abstract The change in fluorescence yield (Δφ) was measured in five species of eucaryotic algae using a ‘pump and probe’ flash technique. The half-time for the oxidation of Q, which was measured by varying the delay time between actinic (pump) and measuring (probe) flashes, averaged 400 μs and was unaffected by background irradiance between 1012 and ...

Characterisation of CO2 and HCO3- Uptake during Steady-state Photosynthesis in the Cyanobacterium Synechococcus PCC7942 Steady-state Photosynthesis in the Cyanobacterium Synechococcus PCC7942

Australian Journal of Plant Physiology, 1994
We have recently developed a mass spectrometric disequilibrium technique to measure CO2 and HCO3- uptake during steady-state photosynthesis in cyanobacteria and microalgae (Badger et al. 1993). Using this technique, we have found differences between the characteristics of Ci uptake in Synechococcus PCC7942 under steady- and non-steady state ...

Fluorescence analysis during steady-state photosynthesis

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1989
Photosynthetic gas exchange of attached leaves has been measured under steady-state conditions at different light intensities and correlated with simultaneous measurements of chlorophyll fluorescence and oxidized P 700 (by absorbance changes at 820 nm).

Air pollutant stress changes the steady-state transcript levels of three photosynthesis genes

Environmental Pollution, 1995
Six-week-old tobacco plants (Nicotiana tabacum L., cv. SR-1) were fumigated with different, but defined and realistic combinations of NO(2), automobile exhaust and ozone for two days. To determine the effect of an additional environmental stress during exposure, plants were either wounded mechanically or treated with salicylic acid to simulate pathogen
