(Submitter supplied) The decision of whether to grow or to divert energy to stress response is a key physiological trade-off for plants seeking to survive under fluctuating environments. However, the cell-to-cell communication underlying this decision is largely unknown. Here we show that three orphan leucine-rich repeat receptor kinases (LRR-RKs) act as direct ligand-perceiving receptors for PSY-family peptides and play a key role in local switching between two opposing pathways. more...

(Submitter supplied) Plants modulate the efficiency of root nitrogen (N) acquisition in response to shoot N demand. However, molecular components directly involved in this shoot-to-root communication remain to be identified. Here, we show that phloem-mobile CEPD-like 2 (CEPDL2) polypeptide is upregulated in the leaf vasculature in response to decreased shoot N status and, after translocation to the roots, promotes high-affinity uptake and root-to-shoot transport of nitrate by activating nitrate transporter genes such as NRT2.1, NRT3.1 and NRT1.5. more...
