TL;DR: The importance of the Vitamin E-Vitamin C thylakoid antioxidant system is examined, in terms of susceptibility to photo-oxidative damage under stress conditions including chilling, ageing and senescence, drought, atmospheric pollutants, herbicides and photosensitizing fungal toxins.

TL;DR: High resolution digital imaging was used to identify sites of photo-oxidative stress responses in Arabidopsis leaves non-invasively and to demonstrate the potential of using a suite of imaging techniques for the study of oxidative metabolism in planta.

TL;DR: SOSG is a useful in vivo probe for the detection of singlet oxygen, which is thought to have a very short half-life in biological systems and, consequently, it is difficult to detect.

TL;DR: Measurements of the quantum efficiencies of photosynthetic electron transport through photosystem II (phiPSII) and CO2 assimilation (phiCO2) were made simultaneously on leaves of maize crops in the United Kingdom during the early growing season, when chilling conditions were experienced, supporting the hypothesis that the relative flux of photosynthesis reducing equivalents to O2 via the Mehler reaction is higher when leaves develop under chilling conditions.

TL;DR: It is suggested that γ-ECS–transformed plants suffered continuous oxidative damage caused by a failure of the redox-sensing process in the chloroplast.
