Nitrogen is an essential element for plant growth and animal nutrition, and is a nutrient that is taken up in a large amount by plants. Limitations in food supply for a growing population, together with the harmful effects of intensive agriculture on the environment, are major challenges to agricultural science. The development of crop plants with improved nitrogen assimilation and management would reduce the need for intensive nitrogen fertilization, and positively influence the environment. Major efforts have been carried out over the last century in order to understand the biochemistry and molecular biology of nitrogen metabolism in plants, and to design how this knowledge may be applied in order to improve crops. In addition, the new high-throughput technologies in biology, along with systems biology approaches, may provide new integrated information about the processes determinants of nitrogen use efficiency (NUE) in plants, and the discovery of new genes involved in the underlying molecular mechanisms. This knowledge could allow for the design of new biotechnological approaches to improve nitrogen management by crop plants, and contribute to developing models of sustainable agriculture with a lower environmental impact. This Special Issue intends to bring together the state-of-the-art in nitrogen metabolism of plants and model microorganisms.

Abstract: Wheat (Triticum aestivum L.) pasture constitutes a major component of cool-season forages in the Southern USA. The objective of this study was to understand the responses of N fertilization on wheat biomass yield, quality and nitrogen use efficiency (NUE). The experiments were conducted in the greenhouse and hoop-house of Noble Research Institute, LLC, in a split-plot design with three replications. Twenty wheat cultivars/lines were evaluated at four N rates (0, 50, 100 and 200 mg of N∙kg-1 soil). The line NF97117 consistently produced high biomass at both the environments. In general, high NUE lines had lower crude protein content than the low NUE lines. None of the cultivars/lines reached a plateau for biomass production or crude protein at the highest N rate. The line×N rate interaction for NUE was not significant in the greenhouse (P=0.854), but was highly significant in the hoop-house (P<0.001). NUE had strong positive correlations with shoot and total biomass, but low to moderate correlations with root biomass. NUE also had strong positive correlation with N uptake efficiency. Lines with high NUE can be used in breeding programs to enhance NUE in wheat for forage use.
