Vitamin C (l-ascorbic acid) is an excellent free radical scavenger, not only for its capability to
donate reducing equivalents but also for the relative stability of the derived …

In this year there is the 40th anniversary of the first publication of plant nitric oxide (NO)
emission by Lowell Klepper. In the decades since then numerous milestone discoveries …

In plant cells the free radical nitric oxide (NO) interacts both with anti-as well as prooxidants.
This review provides a short survey of the central roles of ascorbate and glutathione—the …

Nitric oxide (NO) and hydrogen peroxide (H2O2) are key signalling molecules produced in
response to various stimuli and involved in a diverse range of plant signal transduction …

Recently nitric oxide (NO) has emerged as a key signalling molecule in plants. Here we
review the potential sources of endogenous NO, outline the biological processes likely to be …

With the centenary of the first descriptions of 'hypersensitiveness' following pathogenic
challenge upon us, it is appropriate to assess our current understanding of the …

Cadmium (Cd) toxicity has been widely studied in different plant species; however, the
mechanism involved in its toxicity as well as the cell response against the metal have not …

Potassium (K+) is an essential nutrient required by plants in large quantities, but changes in
soil concentrations may limit K+ acquisition by roots. It is not known how plant root cells …

The inner membrane of a plant mitochondrion contains the mitochondrial electron transport
chain (mtETC), consisting of protein complexes that use an energy source-derived reductant …

Plant resistance to pathogens requires the activation of complex metabolic pathways in the
infected cells, aimed at recognizing pathogen presence and hindering its propagation within …
