Title Perception of root-derived peptides by shoot LRR-RKs mediates systemic N-demand signaling.
Journal Science
Abstract Nitrogen (N) is a critical nutrient for plants but is often distributed unevenly in the soil. Plants therefore have evolved a systemic mechanism by which N starvation on one side of the root system leads to a compensatory and increased nitrate uptake on the other side. Here, we study the molecular systems that support perception of N and the long-distance signaling needed to alter root development. Rootlets starved of N secrete small peptides that are translocated to the shoot and received by two leucine-rich repeat receptor kinases (LRR-RKs). Arabidopsis plants deficient in this pathway show growth retardation accompanied with N-deficiency symptoms. Thus, signaling from the root to the shoot helps the plant adapt to fluctuations in local N availability.
