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.

The paper identifies FT-expressing companion cells in leaves, reveals their unique gene expression profile, and shows that NIGT1 represses FT under nitrogen-rich conditions.

The paper shows that the fungus Colletotrichum tofieldiae promotes plant growth under nitrogen limitation by transferring nitrogen independently of plant nitrate transporters and by attracting beneficial bacteria.

This study identifies ABCC4 as a cytokinin efflux transporter in Arabidopsis, showing its role in root system development through regulation of cytokinin flow.

This study identifies how the endophytic fungus Serendipita indica promotes Arabidopsis growth by altering auxin transport and conjugation through GH3 genes and PIN2 expression.

The paper uses genome resources from Setaria viridis to identify loci associated with climate response, seed shattering, and leaf angle, and validates a novel domestication gene.
