Water deficit caused by drought is a significant threat to crop growth and production. Nitric
oxide (NO), a water-and lipid-soluble free radical, plays an important role in cytoprotection …

During the past two decades, nitric oxide (NO) has evolved from a mere gaseous free radical
to become a new messenger in plant biology with an important role in a plethora of …

Post-translational modifications (PTMs) mediated by nitric oxide (NO)-derived molecules
have become a new area of research, as they can modulate the function of target proteins …

Various data indicate that nitric oxide (NO) is an endogenous signal in plants that mediates
responses to several stimuli. Experimental evidence in support of such signalling roles for …

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 …

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

Metacaspases are distant relatives of animal caspases found in protozoa, fungi, and plants.
Limited experimental data exist defining their function (s), despite their discovery by …

Metacaspases are cysteine-dependent proteases found in protozoa, fungi and plants and
are distantly related to metazoan caspases. Although metacaspases share structural …

The role of reactive oxygen and nitrogen species in local and systemic defense reactions is
well documented. NPR1 and TGA1 are key redox-controlled regulators of systemic acquired …

Nitric oxide (NO), polyamines (PAs), diamine oxidases (DAO) and polyamine oxidases
(PAO) play important roles in wide spectrum of physiological processes such as …
