A NIGT1-centred transcriptional cascade regulates nitrate signalling and incorporates phosphorus starvation signals in Arabidopsis

Plants respond to nutrients by modulating gene expression. Here, the authors show that nitrate suppresses NRT2.1 nitrate transporter expression via NIGT1 transcriptional repressors and that phosphate starvation enhances this pathway via PHR1, thus linking phosphorus and nitrogen signalling.
