•13 barley microRNAs and 2 microRNAs* are nitrogen excess responsive.•Target mRNA levels are in agreement with the cognate microRNA level change.•Identified microRNAs and their targets respond in an opposite way in nitrogen deficiency conditions.•These microRNAs can be regarded as sensors of nitroge...
