Detection of Reactive Oxygen Species in Oryza sativa L. (Rice)
[Abstract]  Superoxide ions (O2-) and hydrogen peroxide (H2O2) are the reactive oxygen species (ROS) that play a significant role in regulation of many plant processes. The level of O2- ions is determined qualitatively using nitrobluetetrazolium (NBT) assay while the H2O2 is qualitatively estimated using 3,3-diaminobenzidine (DAB) and 2’,7’-dichlorodihydrofluorescein diacetate (H2DCFDA) assay. Further the aqueous content of H2 ...

Localisation and Quantification of Reactive Oxygen Species and Nitric Oxide in Arabidopsis Roots in Response to Fungal Infection
[Abstract]  Nitric oxide and reactive oxygen species have emerged as important signalling molecules in plants. The half-lives of NO and ROS are very short therefore rapid and precise measurements are required for the understanding biological roles of these redox active species. Various organelles and compartments generate NO and ROS thus it is important to determine precise location of these free radicals in order to understand their signalling roles. Diaminofluorescen (DAF) and fluorescent 2', ...

Flow Cytometric Detection of Reactive Oxygen Species
[Abstract]  Reactive oxygen species (ROS) are molecules containing hydroxyl radicals or peroxides with unpaired electrons. In healthy aerobic cells, ROS are produced naturally as a byproduct of oxidative phosphorylation, oxidoreductase enzymes, or metal catalyzed oxidation at a controlled rate. However, ROS can be induced under some stress conditions especially exposure to environmental oxidants and certain drugs that leads to oxidative stress. Exceed ROS can cause damages in the building blocks of cells ...
