Root osmotic sensing from local perception to systemic responses

Abstract Plants face a constantly changing environment, requiring fine tuning of their growth and development. have therefore developed numerous mechanisms to cope with environmental stress conditions. One striking example is root response water deficit. Upon drought (which causes osmotic cells), plants can among other responses alter locally system architecture (hydropatterning) or orientate optimize uptake (hydrotropism). They also modify hydraulic properties, metabolism development coordinately at the whole plant levels. Upstream these developmental physiological changes, roots must perceive transduce signals for availability. Here, we review current knowledge on perception discuss how long distance signaling play role in signal integration, leading great phenotypic plasticity
