Water deficiency compromises plant performance and yield in many habitats and in
agriculture. In addition to survival of the acute drought stress period which depends on plant …

The free radicals along with several reactive oxygen species (ROS) and reactive nitrogen
species (RNS) are known to play a dual role in the biological living system which carries a …

Plants are exposed to diverse abiotic stresses like drought, heat, salinity, and high-metal
concentrations at different stages of their life cycle. As protection against stress, plants …

There seems to be no report in the literature on the effect of melatonin (MT) in relieving the
detrimental effects of combined application of salt stress (SS) and iron deficiency (ID) …

Background Melatonin is a pleiotropic signaling molecule that plays multifarious roles in
plants stress tolerance. The polyamine (PAs) metabolic pathway has been suggested to …

In nature, plants constantly have to face pathogen attacks. However, plant disease rarely
occurs due to efficient immune systems possessed by the host plants. Pathogens are …

Nitric oxide (NO) has emerged as an important signal molecule in plants, having myriad
roles in plant development. In addition, NO also orchestrates both biotic and abiotic stress …

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 …

Salinity stress is a chief abiotic hindrance affecting crop productivity and yield particularly in
arid and semi-arid regions across the globe. Plants have evolved a network of physiological …

Losses of nitrogen from the soil/plant system not only reduce soil fertility and plant yield but
can also create adverse impacts on the environment. Ammonia emissions into the …
