Nitrogen (N) availability is a major factor determining plant growth and productivity. Plants
acquire inorganic N from the soil, mainly in the form of nitrate and ammonium. To date …

Plant growth regulators are naturally biosynthesized chemicals in plants that influence
physiological processes. Their synthetic analogous trigger numerous biochemical and …

Plants use nitrate, ammonium, and organic nitrogen in the soil as nitrogen sources. Since
the elevated CO2 environment predicted for the near future will reduce nitrate utilization by …

The extracellular pH is a vital regulator of various biological processes in plants. However,
how plants perceive extracellular pH remains obscure. Here, we report that plant cell …

Melatonin (MT) is a pleiotropic molecule with diverse and numerous actions both in plants
and animals. In plants, MT acts as an excellent promotor of tolerance against abiotic stress …

Background Auxin is a versatile plant hormone with important roles in many essential
physiological processes. In recent years, significant progress has been made towards …

Nitrite is one of the players in the broad nitrogen biogeochemical cycle. This nitrogen oxo-
anion is involved in key pathways crucial to life on Earth and to the planetary “recycling” of …

Under environmental stresses, plant development is adaptively modulated. This modulation
is influenced by the steady‐state balance (homeostasis) between reactive oxygen species …

Saline-alkaline soil affects crop growth and development, thereby suppressing the yields.
Human activities and climate changes are putting arable land under the threat of saline …

Nitrogen is the only macronutrient that is commonly available to plants in both oxidized and
reduced forms, mainly nitrate and ammonium. The physiological and molecular effects of …
