Abstract
Nitrogen is an essential macronutrient required by plants. Nitrogen use efficiency of the plants, by increasing the efficiency of mechanisms plants use to accumulate and utilize nitrogen. Development of crop varieties with high nitrogen use efficiency (NUE) is imperative for sustainable agriculture. Worldwide, the NUE for crop plants is of great concern. One of the most significant contributions of the research community is the improvement in our understanding of the relationship between N availability, N uptake, and overall plant development. N uptake is one of the most critical NUE components under N-limiting conditions in a number of crops; the transfer of knowledge should be relatively straightforward when the experimental procedures have been adapted to larger or structurally different systems grown under agronomic conditions. Understanding the molecular basis of NUE will make enable to provide handle for crop improvement through biotechnological means.
