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...

Cell signalling following plant/pathogen interactions involves the generation of reactive oxygen and reactive nitrogen species (2002)
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.

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...
