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 …

Nitric oxide (NO) is an important molecule that acts in many tissues to regulate a diverse
range of physiological processes. It is becoming apparent that NO is a ubiquitous signal in …

The organization of redox signaling and the use of nitric oxide (NO) to transmit information,
modulate biological processes or create cellular damage are highly complex. Recent reports …

Nitric oxide (NO) is a bioactive molecule that exerts a number of diverse activities in
phylogenetically distant species, as well as opposing effects in related biological systems. It …

As with all organisms, plants must respond to a plethora of external environmental cues.
Individual plant cells must also perceive and respond to a wide range of internal signals. It is …

Nitric oxide (NO) is now seen as a vitally important molecule in many biological systems.
Once it was identified in mammalian systems in 1987 (Palmer et al., 1987) it was only a …

Nitric oxide (NO) is widely recognized for its role as signaling compound. However, the
metabolic mechanisms that determine changes in the level of NO in plants are only poorly …

A decade-long investigation of nitric oxide (NO) functions in plants has led to its
characterization as a biological mediator involved in key physiological processes. Despite …

Nitric oxide (NO) is an essential signal molecule to maintain cellular homeostasis in uni and
pluricellular organisms. Conceptually, NO intervenes as much in sustaining basal metabolic …

There is now general agreement that nitric oxide (NO) is an important and almost universal
signal in plants. Nevertheless, there are still many controversial observations and opinions …
