Genetic regulation of the traits contributing to wheat nitrogen use efficiency

High nitrogen application aimed at increasing crop yield is offset by higher production costs and negative environmental consequences. For wheat, only one third of the applied utilized, which indicates there scope for Nitrogen Use Efficiency (NUE). However, achieving greater NUE challenged complexity trait, comprises processes associated with uptake, transport, reduction, assimilation, translocation remobilization. Thus, knowledge genetic regulation these critical in NUE. Although primary uptake metabolism-related genes have been well studied, relative influence each towards not fully understood. Recent attention has focused on engineering transcription factors identification miRNAs acting expression specific related to Knowledge obtained from model species needs be translated into wheat using recently-released whole genome sequences, exploring variations NUE-related traits wild relatives ancient germplasm. findings indicate basis complex. Pyramiding various will most effective approach achieve a satisfactory level field.
