TL;DR: Suppression of NO signal in the protoplasts isolated in the presence of cycloheximide suggests de novo synthesis of NO generating protein during the process of protoplast isolation and the lack of inhibition of NO production by sodium tungstate and inhibition by l-NNA, and PBIT suggest involvement NOS-like protein, but not nitrate reductase, in NO generation in the leaf chloroplasts and protoplast.

TL;DR: In vivo localization of H2O2 and enzymes involved in H 2O2 generation and detoxification, molecular antioxidant-ascorbate and its redox state and lipid peroxidation were investigated in the leaf and isolated protoplasts to provide new insight into the mechanism of ROS generation in Brassica napus leaf protoplast.

TL;DR: Nitric oxide generation in different plant organs and cellular compartments is summarized and it is hypothesized that NO acts in cooperation with transcription factors such as bHLH, FIT and IRO to regulate expression of enzymes and proteins essential for Fe homeostasis.

TL;DR: A spatial pattern of oxidative stress and antioxidant defence within maize leaf is reported and localization of hydrogen peroxide in different region of leaf clearly exhibits well-defined increasing pattern of accumulation from the base to the leaf tip.

TL;DR: A possibility of mediating electrons to oxygen by an overproduced soluble FNR is reported, and it is suggested that the FNR has a function in utilizing any excess reducing power of NADPH.
