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 …

Nitrate reductase (NR) is a key enzyme for nitrogen acquisition by plants, algae, yeasts, and
fungi. Nitrate, its main substrate, is required for signaling and is widely distributed in diverse …

Abiotic stress is one of the main threats affecting crop growth and production. An
understanding of the molecular mechanisms that underpin plant responses against …

Nitrate assimilation is a key process for nitrogen (N) acquisition in green microalgae. Among
Chlorophyte algae, Chlamydomonas reinhardtii has resulted to be a good model system to …

Nitric oxide (NO) is a gaseous reactive oxygen species (ROS) that has evolved as a
signaling hormone in many physiological processes in animals. In plants it has been …

Leghemoglobins enable the endosymbiotic fixation of molecular nitrogen (N2) in legume
nodules by channeling O2 for bacterial respiration while maintaining a micro-oxic …

Flooding is detrimental for nearly all higher plants, including crops. The compound stress
elicited by slow gas exchange and low light levels under water is responsible for both a …

The natural environment of plants is composed of a complex set of abiotic stresses and their
ability to respond to these stresses is highly flexible and finely balanced through the …

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 …

Dormancy is an adaptive trait that enables seed germination to coincide with favorable
environmental conditions. It has been clearly demonstrated that dormancy is induced by …
