Plants have developed various adaptations in response to hypoxic stress and these have been extensively described. Less well゛ppreciated is the body of evidence demonstrating that scavenging of nitric oxide (NO) and the reduction of nitrate/nitrite regulate important mechanisms that contribute to ...
Plants take up nitrogen in the form of nitrate and ammonia through nitrate assimilation pathway.Nitrate assimilation is highly regulated process by two successive enzymes,nitrate reductase (NR) and nitrite reductase (NiR),which mainly controll the primary nitrogen assimilation.In higher plants,various ...
In the last few years, the role of NO in tolerance of plants to abiotic stress has established much consideration. As it is evident from the present review, recent progress on NO potentiality in tolerance of plants to environmental stresses has been impressive. These investigations suggest that ...
Step-by-Step Solution:1. Identify Nitrogen as a Macronutrient: - Nitrogen is classified as a macronutrient, which means it is one of the essential elements required in large quantities for plant growth and
NO can be generated: (1) enzymatically by NO synthase from l -arginine or nitrite via nitrate reductase; (2) non-enzymatically as a by-product of denitrification, nitrogen fixation and respiration. In plants, NO signalling involves cGMP, cADP ribose, Ca 2+ , salicylic acid and protein ...

Plants must acquire at least 14 mineral nutrients from the soil to complete their life cycles. Insufficient availability or extreme high levels of the nutr
10.1038/ncomms2621 Arabidopsis NIN-like transcription factors have a central role in nitrate signalling Mineko Konishi1 & Shuichi Yanagisawa1 In plants, nitrate is not only a major nitrogen source but also a signalling molecule that modulates the expression of a wide range of genes and that regula...
The role of nitrate in osmotic control was studied with Italian ryegrass grown in a nutrient solution in a climate room. Quantum-flux density, osmotic potential of the nutrient solution and availability of nitrate and chloride were varied independently. Plants at high quantum flux density (650 mol...
plants; among those, cesium is very common radionuclide. Once cesium enters into the plant cell, it can cause phytotoxicity. Therefore, it is desirable to understand complete pathway and mechanisms of cesium uptake in the plants, in order to assess consequences from accidental release of radio...
