Jasmonate restrains the enhanced growth response of lateral roots induced systemically by a local water deficit
Water availability in drying soils is most often spatially heterogeneous, requiring plants to adjust their root system architecture to sustain water uptake. This acclimation response to water deficit (WD) relies on the integration of local and systemic signals. The later and their mode of action remain poorly understood. Using hydroponic split-root systems in maize and Arabidopsis, we show that,…
