Nitrogen, which is one of the most determining factors in the growth, survival andreproduction of plants is unfortunately also one of the most fluctuating elements spatiallyand temporally in the soil. A tight regulation of the expression for the genes involved in itsuptake and transport is therefore decisive. However, some genes involved in nitrogen nutritionpresent a high level of transcriptional variability between plants even in absence of geneticand environmental differences.In this context, we are analysing the role of the high expression variability for the high-affinitynitrate transporter, namely NRT2.1, in the response to fluctuation in nitrate in Arabidopsisthaliana. We will also show our results of the impact of certain fluctuating nitrate conditionson this inter-individual variability
