Nitrogen use efficiency (NUE) is very important for reducing the cost of production, sustainable agriculture and mitigates the environment pollution. It is more so in case of major cereals like wheat, where the NUE is approximately 40%. NUE comprises of Nuptake by the root and then their assimilation, utilization, remobilization by the shoot. However, utilization primarily dependent on available resources, . amount of N-uptaken by the root system. Root system architecture (RSA) and the transporters are key factors which determine the amount of nitrogen forage could be possible by a genotypes at different level of soil nitrogen. | Nitrogen stress leads to induce change in expression of genes for nitrate transporter in wheat genotypes
