This study shows that LBD transcription factors repress local and systemic nitrogen responses in Arabidopsis through distinct pathways, enhancing nitrate uptake and N-related gene expression in their absence.

This study shows that AHK3 and CKX4 in roots regulate tZ-type cytokinin transport via xylem, affecting leaf size based on nitrogen availability.

This study shows shoot nitrate status regulates Arabidopsis growth and gene expression via shoot IPT3, which modulates CKs and transcriptomic responses in shoots and roots.

This study shows that Arabidopsis RFNR1 and RFNR2 are essential for root growth and ferredoxin-dependent processes, as demonstrated by mutant analysis and transcriptome changes.

This study analyzes the transcriptome of Arabidopsis thaliana leaves under high-concentration ammonium sulfate treatment over time, identifying gene expression changes related to stress responses and toxicity mechanisms.

The paper shows that STOP1 dominates Arabidopsis ammonium tolerance over NRT1.1, with STOP1 directly activating NRT1.1 transcription and regulating common target genes.

This study shows that alternative oxidase (AOX) reduces mitochondrial oxidative stress and supports plant growth under limited nitrate reduction in Arabidopsis thaliana.
