Roles of the transcriptional regulation mediated by the nitrate-responsive cis-element in higher plants

► NRE is the cis-element controlling nitrate-responsive transcription in higher plants. ► NRE-mediated regulation is the primary nitrate response in Arabidopsis. ► NRE-mediated regulation is likely to be conserved among various higher plants. ► Changes in the nitrate content cause diurnal gene expression via this regulation.
