About this Research Topic
Nitrogen (N) is the quantitatively most important macronutrient for plants and is taken up by roots in inorganic (ammonium and nitrate) and organic (amino acids, urea) forms. Inorganic N fertilizer has been extensively used in the past few decades, which drives crop yield improvement in agriculture production. Besides its role as a nutrient, N can act as an important environmental signal that triggers physiological responses and morphological changes by regulating gene expression.
N does not work in isolation but frequently interacts and communicates with other nutrients. And plants can manage N to support growth to cope with and survive under diverse stresses, such as nutrient deficiency and ionic stress. Several studies have reported that N can interact with phosphorus, potassium, and iron to mediate their availability. In addition, N affects plant responses to proton, ammonium, iron, zinc, lead, aluminum, and cadmium toxicity. However, many molecular details remain unclear. In-depth understanding and exploration of the molecular mechanisms that underpin the interactions between N and other nutrients are useful in designing effective strategies to improve crop growth, development, and productivity.
The role of N in various abiotic stress responses has attracted increasing attention. This Research Topic aims to explore the effects of N on plant tolerance to various abiotic stresses, especially to nutrient deficiency and ionic stress, such as phosphorus, potassium, and iron deficiencies, or proton, ammonium, iron, zinc, lead, aluminum, and cadmium toxicity. We welcome studies on the physiological, biochemical, and molecular mechanisms of N-regulated adaption to nutrient deficiency and ionic stress, as well as the interactions between N with other nutrients in plants.
This Research Topic will include high-quality Original Research and Review articles on the following topics but are not limited to:
• N-regulated physiological and morphological changes in plants
• N signal transduction in response to nutrient deficiency
• Interactions between N and other nutrients
• Plant- soil acidification interactions triggered by N
• Alleviation of ammonium toxicity
• Heavy metal toxicity and prevention regulated by N
