About this Research Topic
Nitrogen (N) is an important macronutrient for plant growth and development. Research has long been carried out to elucidate plant mechanisms related to N metabolism, important for productivity under stress and non-stress conditions. Despite recent advances, many of these mechanisms are not yet fully understood. In this Research Topic, we hope to present several research studies related to genetic, biochemical, and physiological aspects important for N uptake, assimilation, and utilization in crops and model plant species. Together, the articles in this issue will provide an integrated perspective on important questions related to N physiology, metabolism, and growth in plant organs, highlighting the fundamental importance of diverse plant traits under a climate change scenario.
Nitrogen is a constituent of amino acids, proteins, nucleic acids, chlorophyll, and primary and secondary metabolites, playing a vital role in diverse plant functions. The global demand for crops is increasing rapidly, accompanied by the global environmental impacts of agricultural expansion and anthropogenic emissions. Agricultural systems mainly depend on the mineral fertilizer for agricultural land, and alternatively, on interactions between plants and mycorrhizal fungi, and plant growth-promoting bacteria (PGPB). The projected effects of climate change, including an increase in the frequency and intensity of abiotic and biotic stress combinations, require practical approaches to enhance plant nutrition and nitrogen use efficiency. Implementing strategies such as promoting plant symbioses, employing biostimulants, and selecting appropriate crop varieties is crucial to achieving high future yields. However, further research is needed to elucidate mechanisms and traits related to N metabolism and productivity under stress and non-stress conditions.
The manuscripts in this Research Topic will provide insights into the principles governing the importance of N in the regulation of genetic, biochemical, and physiological processes in crops and model plant species under stress and non-stress conditions, under symbioses with soil microorganisms, in plants treated with biostimulants, or in genetically modified plants. Approaches such as gas exchange, gene expression, omics (metabolomics and transcriptomics), or analyses of the isotopic composition of elements, are welcome to evaluate:
(1) physiological processes
(2) signaling networks
(3) metabolic pathways
(4) element cycling
(5) N uptake, assimilation, and utilization
This Research Topic will include research articles and reviews addressing fundamental and applied topics relevant to nutrition, metabolism, and productivity in crops and model plant species from experiments conducted in growth chambers to field conditions.
