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 …

Ammonium sensitivity of plants is a worldwide problem, constraining crop production.
Prolonged application of ammonium as the sole nitrogen source may result in physiological …

Nitric oxide (NO), a gaseous, redox‐active small molecule, is gradually becoming
established as a central regulator of growth, development, immunity and environmental …

Nitrogen (N) is one of the most important elements that has a central impact on plant growth
and yield. N is also widely involved in plant stress responses, but its roles in host-pathogen …

Plant-associated microbial communities can promote plant nutrient uptake, growth, and
resistance to pathogens [1–3]. Host resistance to infection can increase directly through …

Besides defence pathways regulated by classical stress hormones, distinct amino acid
metabolic pathways constitute integral parts of the plant immune system. Mutations in …

Background Plants require nitrogen (N) for growth, development and defence against abiotic
and biotic stresses. The extensive use of artificial N fertilizers has played an important role in …

Plants under natural environment facing various pathogens, tend to produce defense to
maintain their fitness and minimize pathogenic damage. Plant-pathogens interaction is …

Polyamine (PA) catabolic processes are performed by copper-containing amine oxidases
(CuAOs) and flavin-containing PA oxidases (PAOs). So far, several CuAOs and PAOs have …

Nitrogen (N) is essential for life and is a major limiting factor of plant growth. Because soils
frequently lack sufficient N, large quantities of inorganic N fertilizers are added to soils for …
