The knowledge of post-transcriptional regulation of plant response to nutrients is important to improve nitrogen use efficiency of crop. Our work was aimed at understanding the role of miRNAs in the molecular control of maize response to nitrate. Six nitrate responsive miRNAs were identified in roots of young seedlings and their expression was deeply studied in response to nitrate supply, through both qPCR and in situ hybridization. Results obtained pointed out the potential role of nitrate-responsive miRNAs at the posttranscriptional level in the regulation of the metabolic, physiological and morphological adaptations of maize seedling survival under nitrate-deficient conditions.
