Nitric oxide signalling in plants (2003)
Journal Article
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 mediated by NO, and discuss the downstream signalling processes by whi...

Nitric oxide as a mediator of ABA signalling in stomatal guard cells (2003)
Journal Article
A new role for an old enzyme: Nitrate reductase-mediated nitric oxide generation is required for abscisic acid-induced stomatal closure in Arabidopsis thaliana (2002)
Journal Article
The plant hormone abscisic acid (ABA), synthesized in response to water-deficit stress, induces stomatal closure via activation of complex signaling cascades. Recent work has established that nitric oxide (NO) is a key signaling molecule mediating AB...

Antimicrobial properties of milk: Dependence on presence of xanthine oxidase and nitrite (2002)
Journal Article
Human and bovine milk inhibited the metabolic activity of Escherichia coli, as shown by luminescence monitoring of constructs expressing the luxCDABE genes. Inhibition was dependent on both xanthine oxidase (XO) activity and on the presence of nitrit...

Hydrogen peroxide and nitric oxide as signalling molecules in plants (2002)
Journal Article
It is now clear that hydrogen peroxide (H2O2) and nitric oxide (NO) function as signalling molecules in plants. A wide range of abiotic and biotic stresses results in H2O2 generation, from a variety of sources. H2O2 is removed from cells via a number...

Regulation of the Arabidopsis transcriptome by oxidative stress (2001)
Journal Article
Oxidative stress, resulting from an imbalance in the accumulation and removal of reactive oxygen species such as hydrogen peroxide (H2O2), is a challenge faced by all aerobic organisms. In plants, exposure to various abiotic and biotic stresses resul... Read More about Regulation of the Arabidopsis transcriptome by oxidative stress.
Nitric oxide evolution and perception
Presentation / Conference Contribution
Various experimental data indicate signalling roles for nitric oxide (NO) in processes such as xylogenesis, programmed cell death, pathogen defence, flowering, stomatal closure, and gravitropism. However, it still remains unclear how NO is synthesize... Read More about Nitric oxide evolution and perception.
Doing the unexpected: Proteins involved in hydrogen peroxide perception
Presentation / Conference Contribution
A look back at the early literature on reactive oxygen species (ROS) gives the impression that these small inorganic molecules had a singular defined role, that of host defence in mammalian systems. However, it is now known that their roles also incl... Read More about Doing the unexpected: Proteins involved in hydrogen peroxide perception.
The role of stigma peroxidases in flowering plants: Insights from further characterization of a stigma-specific peroxidase (SSP) from Senecio squalidus (Asteraceae)
Presentation / Conference Contribution
Angiosperm stigmas have long been known to exhibit high levels of peroxidase activity when they are mature and most receptive to pollen but the biological function of stigma peroxidases is not known. A novel stigma-specific class III peroxidase gene,...

Cytochrome c, Glutathione, and the Possible Role of Redox Potentials in Apoptosis
Presentation / Conference Contribution
The redox environment of the cell is now thought to be extremely important to control the activity of many proteins. During apoptosis, the intracellular redox potential (Eh) becomes more positive, with possible consequences for the mechanisms of apop...

Cell signalling following plant/pathogen interactions involves the generation of reactive oxygen and reactive nitrogen species
Presentation / Conference Contribution
It is now clear that reactive oxygen species (ROS), such as hydrogen peroxide (H2O2), and reactive nitrogen species, such as nitric oxide (NO), are produced by plant cells in response to a variety of stresses, including pathogen challenge. Such molec... Read More about Cell signalling following plant/pathogen interactions involves the generation of reactive oxygen and reactive nitrogen species.
