Phosphate Resupply Differentially Impacts the Shoot and Root Proteomes of Arabidopsis thaliana Seedlings.

ABSTRACT: Phosphate (Pi) is an essential macronutrient for plant development that is often limited in soil. Plants have evolved dynamic biochemical, physiological and morphological adaptations to cope with Pi deficiency, known as the Pi starvation response (PSR). While many components of the PSR have been well-characterised, less is known about how metabolic homoeostasis is re-established upon Pi resupply, particularly tissue- and time-specific adaptations. Here, we applied label-free quantitative proteomics to quantify protein-level changes in Arabidopsis thaliana shoots and roots following Pi resupply after prolonged Pi deprivation. Sampling at 1 h and 48 h time-points, we captured immediate signalling and metabolic responses, along with longer-term recovery processes. Early responses prioritised
