The Dynamics of Xylem Sap pH under Drought: a Universal Response in Herbs?
Popis výsledku v původním jazyce
Long distance signals in xylem from roots to leaves are important in plant response to drought stress. Abscisic acid (ABA) plays a key role in drought signaling in plants but apoplastic pH may modulate its effect by distributing ABA into various compartments in leaves. We aimed to reveal the dynamics of changes in sap pH and its relationships with the transport of inorganic and organic ions in eight herbaceous plant species under continuously declining soil water content. We tested several hypotheses related to the mechanism of pH changes in xylem. We used a pressure chamber to collect xylem sap and to measure of leaf/stem water potential at various stages of soil drying. We measured pH and concentrations of the most abundant inorganic (NO3, SO42, PO43 and Cl) and organic (malate and citrate) anions in xylem sap. Species differed considerably in the dynamics of pH changes in xylem in drying soil.
