Project description:NRT1.1 is a nitrate transceptor involved in many nitrate responses including the regulation of gene expression through (i) the Primary Nitrate Response (PNR) and (ii) the regulation the NRT2.1 gene under continuous high NH4NO3 conditions. Phosphorylation of NRT1.1’s T101 residue is involved in the modulation of the PNR whereas nitrate transport by NRT1.1 is not. Here we used various NRT1.1 point mutants to study the impact of NRT1.1 on the whole transcriptome under high NH4NO3 supply. Col is the WT control, chl1-5 and chl1-12 are KO mutants, chl1-9 is defective in nitrate transport but not in PNR induction, T101D and T101A mimick the phosphorylated and not phosphorylated forms of NRT1.1 respectively. This work studies the impact of various NRT1.1 mutations on the transcriptome under 10mM NH4N03 supply.

Project description:In higher plants, NAD synthesis starts with the oxidation of aspartate. This oxidation is catalyzed by aspartate oxidase (AO) encoded by a nitrate-inducible gene. To assess the effects of this upregulation of AO gene in response to a nitrate supply, a transgenic line was generated by introduction of AO gene under the control of a mutated AO promoter into the ao knockout mutant. Since, unlike the wild-type AO promoter, this mutated AO promoter was not activated by a nitrate supply, gene expression in this transgenic line was compared with that in another transgenic line that was generated by introduction of AO gene under the regulation of the wild-type AO promoter into the ao knockout mutant. Changes in gene expression in response to a nitrate supply were analyzed in these transgenic lines.
